Which electrode and wire

[boxoftricks]

Just getting set up and have a few questions I'm hoping someone can help with.

What's the best electrode and wire to use learning on steel for DC TIG? It's with a Parweld XTM201

What regulator is recommended for a SGS argon bottle?

Thanks

Red tungsten - mild steel filler, 1mm to 1.6mm will do - normal argon regulator fits those bottles, but get a “peashooter” flowmeter and stick to between 8-10 litres per minute for most jobs.

I like to use 2% lanthanated, don’t Cage about the radioactive Parts of thoriated. But the blue 2% lanthanated work better on Low ampererage Starts and a 2.4mm will do anything a 200 Amp Machine is capable of.

for filler i like ER70S6 which flows nice.

But the most important is cleaning you base Metal

Ive been using blue lanthnated just because im not a serious tig guy its there to aid my work and im more than happy with them ac and dc.

If you are doing steel i use either a15 or a18 as again im not working to strict rules just making something either happen or work
