PrimeWeld CUT60 vs YESWELDER CUT-55DS
One costs several times the other and cuts thicker plate. On a household outlet, the cheaper machine publishes more amps. Both of those things are true, and which matters depends entirely on your circuit.

The short answer
Buy the PrimeWeld CUT60 if you have a 240 V circuit: 20 to 60 A, up to 7/8 inch published capacity, a blowback non-HF arc start that will not interfere with electronics, and a published three-year warranty. Buy the YESWELDER CUT-55DS if you do not: it publishes 10 to 35 A on a 110 V outlet against the CUT60's 20 to 30 A, throttles lower for thin sheet, and costs a fraction as much. Both are non-touch pilot-arc machines with a 60% duty cycle at maximum output, and both need a compressor sustaining 5 to 6 CFM that neither includes.
These two are not really rivals on price — one is several times the other — and that is exactly why the comparison is worth writing. The question is not which is better. It is whether the money buys you anything you can use on the circuit and compressor you already own. The best plasma cutters for home use ranks the field if you are not down to two yet.
What the two machines publish, side by side
| Specification | PrimeWeld CUT60 | YESWELDER CUT-55DS |
|---|---|---|
| Input power | 120 V or 240 V, single phase, 50/60 Hz | 110 V or 220 V, 60 Hz |
| Output on the low voltage | 20–30 A | 10–35 A |
| Output on the high voltage | 20–60 A | 10–55 A |
| Duty cycle | 60% at maximum; 100% at 23 A (120 V) / 46 A (240 V) | 60% at 55 A; 100% at 35 A (110 V) |
| Rated cut | Not published as a separate figure | 3/8 in at 220 V; 5/16 in at 110 V |
| Clean cut | Not published as a separate figure | 1/2 in maximum |
| Cutting capacity | Up to 7/8 in (20 mm) | 3/4 in severance at 220 V; 9/16 in at 110 V |
| Arc start | Blowback non-HF pilot arc, CNC compatible | Non-touch pilot arc, HF ignition |
| Air pressure | 40–75 PSI | 55–70 PSI at 220 V |

Four rows decide this. The low-voltage output, which goes the opposite way to the price. The arc start, which is the only genuine technology difference on the page. The air flow, which is a purchase neither machine includes. And the warranty, where only one of them publishes a number.
The 110-volt row goes to the cheap machine
This is the finding that made the page worth writing, and it runs against the price. On a household outlet PrimeWeld publishes 20 to 30 A. YESWELDER publishes 10 to 35 A. The cheaper machine has more output at the top of the household range and a lower floor at the bottom of it.
That is not a manufacturing surprise, it is physics and marketing meeting. A 60 A machine is designed around a 240 V supply and its 120 V mode is a convenience; a 55 A machine designed to be the cheapest dual-voltage option in the market treats the 110 V mode as a selling point and tunes for it. If the circuit in your garage wall is what you have, the second design serves you better.
So the honest reading is this: the CUT60 is not a 60 A machine you own, it is a 60 A machine you own once you have the circuit. What size breaker a welder needs covers working out whether that circuit is a weekend of work or an electrician's invoice, and 120V vs 240V is the wider version of the same decision.
Blowback versus high frequency, and when it bites
Both machines start their arc without touching the work, which is the feature worth having — a pilot arc will light on painted, rusted or galvanized steel where a touch-start machine stalls and sticks. How they do it differs, and that is the real technology gap here.
PrimeWeld uses a blowback start: air pressure moves an electrode internally to strike the pilot arc, with no high-frequency burst. YESWELDER uses high-frequency ignition, which strikes through the air gap with a radiated HF pulse. Both work. The HF pulse is also radio-frequency interference, and it can upset nearby electronics, trip sensitive circuits and make a CNC table unhappy — which is why PrimeWeld publishes CNC compatibility and YESWELDER does not.
If the machine will live on a bench and cut by hand, this row costs you nothing. HF vs non-HF plasma cutters goes through what the interference actually affects. If you have ever thought about a cutting table, it is the row that decides the purchase.
Air is the cost neither price includes
PrimeWeld publishes 5 CFM at 90 PSI. The CUT-55DS listings publish up to 6.0 CFM. Those are close enough to be the same requirement, and both are well beyond what a small pancake compressor can sustain.
A pancake compressor will cut for perhaps thirty seconds and then spend the next two minutes catching up, which is not a duty cycle problem with the plasma cutter — it is the compressor deciding how long you cut for. Worse, a struggling compressor delivers warm, wet air, and moisture in the torch destroys consumables faster than anything else you can do to a plasma cutter.
Budget the compressor as part of either machine, and put a water separator between it and the torch. Plasma cutter air requirements works through what tank size and CFM rating actually sustain a cut, and plasma cutter consumables explained covers what wet air costs you in tips.
If you do not own a compressor at all
The third pick on this page exists for exactly that case. A machine with an internal compressor cuts less thickness and costs more up front, but it is the only honest comparison when the alternative is buying a plasma cutter plus a compressor plus a hose plus a separator.
Thickness: read the four different numbers carefully
PrimeWeld publishes one figure — up to 7/8 inch (20 mm). The CUT-55DS listings publish four: a rated cut, a clean cut maximum, and severance figures for each voltage. They are not measuring the same thing, and comparing the biggest number on each side is how people end up disappointed.
A rated or recommended cut is thickness the machine will cut repeatedly at a working speed with a square edge. A clean cut is the most it will do with an edge you would weld without grinding. A severance cut is thickness it will get through at all, slowly, with dross you will spend time removing. The useful comparison is rated against rated, and on that basis the CUT-55DS is a 3/8 inch machine on 240 V while PrimeWeld's single 7/8 inch figure sits nearer the severance end of the scale.
Our plasma cutter cut thickness chart sets out the three definitions with the amperage each needs, and it is the page to read before you take any manufacturer's headline thickness at face value.
Consumables and the torch line
PrimeWeld ships an IPT60. YESWELDER ships an AG-60. The AG-60 pattern is the most widely cloned consumable line in budget plasma, which cuts both ways: tips and shields are cheap and available from dozens of sellers, and quality varies enough between sellers that a bad batch reads as a machine fault.
Consumable cost is the real running cost of plasma cutting, and it scales with how hard you push the machine. A 60 A machine cutting quarter-inch plate at 30 A is barely working; a 55 A machine doing the same job near its ceiling is eating tips. That is the quiet argument for capacity headroom, and it is more persuasive than the headline thickness figure.
What neither of them includes
Neither includes air, as above. Neither includes eye protection, and a plasma arc needs a lighter shade than welding rather than a darker one — the best welding helmets for plasma cutting covers why, and VIKING 3350 vs Sentinel A60 compares two helmets whose shade ranges both start low enough to cut in.
And neither is a substitute for a grinder on thin work. If most of what you cut is under an eighth of an inch, plasma cutter vs angle grinder is the honest version of this decision, and it does not always come out in favor of plasma.
How we decided this
Published figures only, labeled by source. PrimeWeld's numbers are PrimeWeld's. YESWELDER's are the ones retailer and specification listings carry, because YESWELDER no longer publishes a page for this model — and the table says so rather than passing them off as manufacturer copy. We have cut with neither machine; see how we pick.
A row that favors the cheap machine gets published. The 110 V output comparison runs against the price and against the framing on our own roundups. It is in the snippet at the top of this page for that reason.
Thickness claims get normalized before they get compared. Rated, clean and severance are three different measurements, and a comparison that lines up the largest number on each side is not a comparison.
The compressor counts as part of the price. A 5 CFM requirement is a purchase. Any honest total for either machine includes it. If you want the field ranked by price band instead, plasma cutters at the entry end of the market and the best dual voltage plasma cutters are the wider versions of this decision.
What we would buy
1. The one to buy if you have 240 V
PrimeWeld CUT60
60 A, up to 7/8 in capacity, a non-HF blowback arc that will not upset electronics, and a published 3-year warranty — on a 240 V circuit, which it needs to be itself.
PrimeWeld publishes 120 V or 240 V single-phase input, 20 to 30 A of output on 120 V and 20 to 60 A on 240 V, a 60% duty cycle at maximum output with 100% at 23 A on 120 V and 46 A on 240 V, cutting capacity up to 7/8 inch (20 mm) steel, an air requirement of 40 to 75 PSI and 5 CFM at 90 PSI, an IPT60 torch, a weight of 30 lb, a blowback non-HF pilot arc described as CNC compatible, and a three-year warranty.
The reason to buy it is the pair of rows nothing cheaper matches: real 60 A output and a blowback, non-high-frequency arc start. Sixty amps is the difference between treating half-inch plate as a careful severance cut and treating it as a job. Capacity headroom is also consumable life — a machine working at 60% of its rating burns tips far more slowly than one pinned at its ceiling, which is where the running cost of plasma actually lives.
The non-HF start is the specification most buyers overlook and the one most likely to matter later. A high-frequency start radiates interference that can upset nearby electronics, and it is the reason HF machines are awkward on a CNC table. PrimeWeld publishing CNC compatibility is not marketing noise; it is what the blowback start buys you.
Two honest costs. On a 120 V outlet it publishes 20 to 30 A — less than the YESWELDER does on the same circuit — so the capacity you are paying for only exists once you have run 240 V. And 5 CFM at 90 PSI is a genuine compressor requirement, not a footnote.
What works
- 60 A gives real headroom on 1/2 in plate instead of treating it as a severance cut
- Pilot-arc start and a well-regarded torch for the price
What does not
- Air demand at 60 A is beyond what a small compressor can sustain — budget for the compressor as part of the purchase
- Dual voltage, but on 120 V PrimeWeld publishes only 20–30 A — half the machine. The 60 A you are paying for needs a 240 V circuit
2. The one to buy if you have not run the circuit yet
YESWELDER CUT-55DS
10 to 35 A on a household outlet, 10 to 55 A on 240 V and a pilot arc, for a fraction of the money — with HF ignition and an unpublished warranty.
Published figures for the CUT-55DS are 110 V or 220 V input, 10 to 55 A on 220 V and 10 to 35 A on 110 V, a 60% duty cycle at 55 A and 100% at 35 A, a rated cut of 3/8 inch (10 mm) on 220 V and 5/16 inch (8 mm) on 110 V, a half-inch maximum clean cut, a severance cut of 3/4 inch on 220 V and 9/16 inch on 110 V, an air requirement of 55 to 70 PSI and up to 6.0 CFM, an AG-60 torch, and a non-touch pilot arc with high-frequency ignition.
Its real argument is the 110 V row. Thirty-five amps on a household outlet against the CUT60's thirty is a genuine win for the cheaper machine, and the amperage range starting at 10 A rather than 20 A means it can be turned down far enough for thin sheet. If the circuit you own is the one in your garage wall, this is the machine that does more on it.
The second argument is the lower end of the output range. A plasma arc that will throttle to 10 A is usable on 18-gauge sheet without blowing straight through it. A machine whose floor is 20 A is not, whatever its ceiling.
What it costs you: HF ignition rather than blowback, so interference is a live concern and a CNC table is not a plan; the AG-60 consumable line is cheap and widely cloned, so quality varies by seller; owner reports show more unit-to-unit variation than the established brands; and no warranty period appears on the specification listings, so treat the term as something to confirm on the listing rather than a number.
What works
- Pilot arc at the bottom of the market, which used to mean paying twice as much
- Dual voltage, so a 110 V outlet gets you started
What does not
- Consumables are the running cost and they do not last like the name brands
- Owner feedback reports more variation between units than the established brands
Who this is wrong for: Anyone cutting half-inch plate regularly, and anyone who wants the machine on a CNC table. Both of those point at the CUT60.
3. If you do not own a compressor
Lincoln Electric Tomahawk 30 AIR
Both machines above assume a compressor you may not have. This one carries its own, and publishes 25 A at a 100% duty cycle.
Lincoln publishes 15 to 30 A of output with 25 A at a 100% duty cycle and 30 A at 60%, an internal air compressor with an external air connection also standard, 230 V single-phase input drawing 16 A at rated output, a recommended cut of 5/16 inch mild steel at 22 inches per minute, a maximum cut of 3/8 inch and a severance cut of 1/2 inch, 40 lb, an LC30 hand torch on a 10 ft lead, and three years on the machine with one on the torch.
It belongs on this page because the comparison above hides a cost. Neither the CUT60 nor the CUT-55DS includes air, and a compressor that can actually sustain 5 to 6 CFM is a several-hundred-dollar purchase and a loud one. If you do not already own that compressor, the honest total for either machine is higher than its price.
What it costs you: far less capacity — 3/8 inch maximum against the CUT60's 7/8 — and 230 V only, so it does not solve the household-circuit problem the YESWELDER solves. The internal compressor is also a second thing that can fail inside a sealed case.
What works
- The compressor is inside the machine, so the hidden second purchase that sinks most first plasma buys does not exist
- It takes external air as standard as well, so a shop compressor can carry the long cuts the internal pump has to pause for
- 25 A at a 100% duty cycle is a genuinely continuous rating rather than a figure you have to work around
- Lincoln publishes three years on the machine and a dealer network behind a tool that eats consumables
What does not
- 230 V single phase only. There is no 120 V option, so a garage without a 240 V circuit cannot run it at all
- 40 lb, which is portable for a machine carrying its own compressor but not the under-30-lb class
- Costs multiples of a budget 50 A machine while cutting thinner material
- Buy on the 5/16 in recommended figure: 1/2 in is a severance limit at 5 ipm, not a working thickness
Questions people actually ask
Is the PrimeWeld CUT60 worth the extra over the YESWELDER CUT-55DS?
On a 240 V circuit, yes, if you cut plate. PrimeWeld publishes 20 to 60 A against 10 to 55 A, a capacity of up to 7/8 inch, a blowback non-HF arc start that is CNC compatible, and a three-year warranty that YESWELDER's listings do not state.
On a 110 V household outlet, no. PrimeWeld publishes 20 to 30 A on the low voltage and YESWELDER publishes 10 to 35 A, so the cheaper machine does more on the circuit you are likely to have.
Which plasma cutter is better on a 110V outlet?
The YESWELDER CUT-55DS, on the published figures. It states 10 to 35 A on 110 V with a rated cut of 5/16 inch; PrimeWeld states 20 to 30 A on 120 V.
The lower floor matters as much as the higher ceiling here - an arc that throttles to 10 A is usable on thin sheet, where one that starts at 20 A will tend to blow through it.
What is the difference between a blowback and an HF pilot arc?
Both start the arc without touching the work. A blowback start uses air pressure to move an internal electrode and strike the pilot arc; an HF start strikes across the gap with a high-frequency pulse.
The practical difference is interference. The HF pulse is radio-frequency energy that can upset nearby electronics and makes a CNC table awkward, which is why PrimeWeld publishes CNC compatibility for the blowback CUT60 and YESWELDER does not for the CUT-55DS. For hand cutting on a bench, it changes nothing.
What size air compressor do these plasma cutters need?
PrimeWeld publishes 5 CFM at 90 PSI for the CUT60; CUT-55DS listings publish up to 6.0 CFM. Neither machine includes air, and neither requirement is met by a small pancake compressor.
A compressor that cannot sustain the flow does two things: it limits how long you cut, and it delivers warm wet air that destroys torch consumables quickly. Budget a compressor that holds the CFM at pressure, plus a water separator, as part of buying either machine.
Can the CUT60 really cut 7/8 inch steel?
That is PrimeWeld's published figure, and it sits nearer the severance end of the scale than the working end. A severance cut is thickness a machine will get through slowly, with dross to clean up afterward - not thickness it will cut repeatedly with a square, weldable edge.
For comparison, the CUT-55DS publishes a rated cut of 3/8 inch on 220 V and a 3/4 inch severance cut. Compare rated against rated, not headline against headline.
Do both machines have a pilot arc?
Yes. Both are non-touch pilot-arc machines, which is the feature worth insisting on at any price. A pilot arc lights before the torch reaches the work, so it will start on painted, rusty, galvanized or expanded metal where a touch-start machine stalls and sticks its tip to the plate.
The difference between them is how the pilot arc is struck - blowback on the CUT60, high frequency on the CUT-55DS - not whether they have one.
Which has the better warranty?
PrimeWeld publishes three years on the CUT60. No warranty period appears on the specification listings for the CUT-55DS, so treat the term as something to confirm on the listing you buy from.
On a tool that consumes tips and shields continuously, the brand you can get parts and support from is worth more than the headline amperage. That is a real part of the gap between these two.
