Find your level before you spend a penny

Almost every welding buying guide on the internet is organized by process. MIG here, TIG there, stick somewhere at the bottom. That is a useful way to organize a catalog and a terrible way to help someone decide, because nobody wakes up wanting a gas metal arc welding machine. They wake up wanting to fix a trailer, build a gate, or make something out of steel that did not exist yesterday.

Arc & Bead is organized the other way round: by the level you are actually at. Four rungs, each defined by what you can build and what stops you, with a specific machine class at each one. Find the rung that describes you and the buying decision mostly makes itself.

The four levels

The ladder is not a ranking of skill for its own sake. Each rung is defined by a practical constraint — power, gas, metal type, and whether you are joining metal or shaping it.

Level 1 · Flux-Core — you have never struck an arc

One machine, a standard wall socket, no gas bottle. Flux-cored wire carries its own shielding inside the wire, which is why it works in a breezy garage and why it leaves slag behind. A 120-volt flux-core machine will weld a garden gate, a trailer hitch, a workbench frame and a mower deck repair. It will not weld half-inch plate and it will not weld aluminum.

This is where the overwhelming majority of people should start, and the first welder to buy walks through exactly what that machine needs to do.

Level 2 · MIG — you can lay a bead and you are tired of slag

Gas MIG swaps the flux inside the wire for a shielding gas from a bottle. The trade is concrete: you gain a much cleaner weld with far less spatter and no slag to chip, and you lose portability and gain a bottle, a regulator and a running gas cost. It is also the level where 240-volt power starts to matter, because that is what lifts you past about a quarter inch of steel in a single pass.

Level 3 · TIG — you want the weld to look deliberate

TIG separates the heat from the filler. You hold an arc with one hand, feed rod with the other, and control amperage with a foot pedal. It is slower and harder than wire welding and it is the only one of these processes that will give you a clean weld on thin stainless or on aluminum. AC output is the specific capability that makes aluminum possible at all, and it is the single thing to check before buying a TIG machine.

Level 4 · Plasma — you are fabricating, not just joining

At some point cutting becomes the bottleneck rather than welding. An angle grinder cuts straight lines slowly and curves badly. A plasma cutter follows a drawn line through quarter-inch plate at walking pace. It needs clean dry compressed air and, above about 40 amps, a 240-volt circuit.

The two decisions that cut across every level

Two questions recur at every rung, and they are where most purchases actually go wrong — not in choosing the machine, but in the things the machine assumes you already have.

The first is power. A machine you cannot plug in is a machine you do not own yet. 120V versus 240V is the decision that sets your ceiling, and what size breaker a welder needs is the question that decides whether you are buying a welder this weekend or booking an electrician first.

The second is what goes over your face. A helmet is not an accessory; it is the thing that decides whether you can see what you are doing, and a bad one is the most common reason a beginner's welds look worse than their technique. Helmets & PPE covers it at every level.

How to use this site

Pick the level that describes you now — not the one that describes what you want to build eventually. Each level hub tells you who it is for, what it lets you make, what the machine at that level costs you in setup and running terms, and the exact signal that means you have outgrown it.

If you are genuinely unsure, the four-way process comparison lays all four side by side in one table, and the starter kit checklist covers everything that is not the welder — which routinely adds up to more than people budget for.

One more thing worth saying plainly before you read any recommendation on this site: we have not physically tested these machines. How we pick sets out exactly what the recommendations are based on instead, which is published manufacturer specifications, arithmetic about duty cycle and power, and the pattern of owner feedback across retailers. We would rather tell you that than imply a workshop we do not have.
