Lift Tig

[Lancs Lad]

As per title being playing with my new esab this week trying lift Tig.. sh*t it's hard...maybe I'm just dumb but has anyone got any tips?
Pure Argon on plain mild steel. With 2.4 tip.
Wire prob tad thin but all I had with places shut.

should only need pure Ar on S/steel, ali, etc. ........ IIRC Argoshield light (5%) should do for MS (and 1/2 price of Ar)?? @Quattromike ??? ..... very long time since I picked up a TIG torch and only on SS/ali

LL remember rule no 1 for a good weld of any description ....... be comfortable ..... not hanging by your toe nails/whatever -- only when you have to

Aye pure argon works well with mild steel, I've never used a mix unless it's with the mig. Plus not worth having 2 bottle hires for occasional use. What thickness is your parent metal? As ever prep is key, clean set up gives clean welds, I would start with 140amps an 12/14 LPM on the gas. Tip out past the ceramic 3/5 mm, Also it scratch start so you want a slight arc motion to touch down and lift a few mm clear to start the arc, you don't want to be stabbing in as it can knacker the point of tungsten, red tip for mild steel.
Strike your arc get a weld pool going and dip the rod into the weld pool

Also it scratch start....

Geez - I didn't realise anyone still did a scratch start. That's just making it hard.

Don't forget the shape you grind the tip alters the arc behaviour.
