Tig welding
dern - 26/10/06 at 11:39 AM

I'm very interested in joining the tig group buy bought would very much appreciate some advice...

I bought a mig kit to build my chassis and taught myself to mig weld. Never had any formal training but it wasn't too difficult to teach myself from a book combined with destructive testing on the stuff I made coupled with posting pics of my efforts on here. My question is can I do the same with tig?

Thanks,

Mark

If you know how to destructivly test items youve welded and know what to look for then yes, Although it is a little trickier to start with than mig and im sure if you get stuck a quick post on here will have plenty of people posting pointers.

Last time i did some welding i was better at tig than mig with about the same amount of pratice on both....

TIG is more controllable and i think its easier in that respect.

what gas do you need for tig then?

Hi Mark.

The short answer is yes.


You would however save time and gas if you could find someone who could spare a couple of hours
to show you the basics, plant set up etc. I think I'm a bit too far away.

I'd advise not using a foot pedal to start with, co ordinating left and right hand is enough to begin with.
A thickish bit of mild steel, say 2 to 3mm and your away.

Gas (argon) is always a problem. Throw aways are expensive, and last no time at all;
a proper full size cylinder is expensive to rent.


Over 100 amps and an air cooled torch gets too hot to hold, but the duty cycle on cheaper welders
don't let you use them continuous anyway.

Thanks guys. I'll investigate how I can get an argon cylinder locally and then join in the bulk buy
