Re: TIG Welding
YouTube Welding tips and tricks, he's got some great advice and close up footage of tig welding.
I've got a acdc tig for most metals inc ally, I'm still learning the ropes myself, tho its common at my work tigging s,steel tanks. My machine cost $750 and is a 200amp inverter model with loads of dials , switches and a digital screen !
Gas is almost always Argon for most metal, ally.
Even tho my machine is an eBay special... I had a guy tig a canopy in ally for a camper and he said after 6hrs of solid welding that its as good as his $3k work tig !!
