Wolfram -Elektroden, TIG -Verbrauchsmaterial

A gas lens, a foot pedal for amp control, and fresh lanthanated tungsten. The gas lens steadies the argon shield, the pedal lets you taper the puddle at the end of a weld, and clean tungsten stops arc wander.

For steel and stainless it is close to essential - you ramp heat in and out for crisp starts and fills. Simder TIG machines support pedal amperage control; check each listing for pedal inclusion.

Two or three tungstens in your working size, spare collets and cups, and a spare gas lens. They are cheap, wear predictably, and each one failing mid-weld stops the whole job.

Yes - 100% argon is the standard TIG shielding gas for steel, stainless, and aluminum alike. Do not use MIG mixed gas (argon/CO2) on a TIG torch; CO2 contaminates the tungsten.
