  • Ceriated tungsten starts easily at low current, where other types splutter
  • 1.6 mm (0.06 in) is the right diameter for thin stainless and small work
  • 1.6 mm (0.06 in) overheats and balls up if pushed past roughly 120 A

Best for: Thin stainless, small brackets and any work under 100 A

Small work, small electrode

Fitting a 2.4 mm (0.09 in) tungsten and turning the machine down does not produce a low-amperage arc — it produces a wandering one. Matching the electrode to the current band is what makes 30 A welding possible.

Handle with a little care

At 1.6 mm (0.06 in) the electrode is slender enough to snap if it dips into the pool and is pulled sideways. Keep spare ground tips ready so a dip does not end the session.

The questions welders ask

Why does the diameter matter so much?

Because a tungsten has a current band. Too much current for the diameter and the tip melts and balls, spitting tungsten into the weld; too little current for a thick electrode and the arc wanders because the tip never gets hot enough to emit properly. 1.6 mm (0.06 in) is comfortable roughly from 40 to 120 A, which is exactly the thin-material range.

Ceriated or lanthanated?

Both are good general-purpose choices and the difference is at the extremes: ceriated starts more reliably at very low current, lanthanated holds up better at high current. If you weld thin material at low amps, grey is the better box; if you do everything, the gold WL-15 covers more ground.
