What the pulse function does On a TIG welder, pulse switches the output between a higher peak current and a lower background current. The peak helps form the puddle; the…

Aluminum oxide is the thin, tough film that forms on aluminum as soon as clean metal meets air. It melts at roughly 3,700°F (2,040°C), while the aluminum beneath it melts…

TIG welding carbon steel is straightforward when the tungsten, joint, filler, and shielding gas stay clean. Most tungsten contamination happens when the electrode touches the puddle or filler rod, but…

When TIG makes sense for a thin stainless fillet TIG gives you control over a small weld pool, which helps when joining thin stainless without burning through or leaving a…

Arc wandering during TIG welding shows up as a wandering arc, an arc that pulls sharply to one side, or a puddle that refuses to stay centered under the tungsten.…

Adding filler smoothly is mostly a timing and distance problem: keep the tungsten steady, hold a short arc, and feed small amounts of rod into the edge of the molten…

What a TIG Gas Lens Does A TIG gas lens replaces the torch’s standard collet body with a gas-distribution component that spreads shielding gas more evenly around the tungsten. A…

Argon flow rate is one of the easiest TIG settings to get wrong. Too little gas leaves the tungsten and weld pool exposed to air. Too much gas can create…

Why fit-up matters on stainless steel A TIG weld can look tidy while still having a weak root, sugared backside or heat-distorted joint. On stainless steel, fit-up has a big…

Brass plumbing components are awkward TIG work. Brass conducts heat quickly, melts at a relatively low temperature, and can release zinc fumes when overheated. A good welder helps, but torch…
