What are your thoughts on a tig welder. At work all our coiled tubing butt welds are done with tig. X-rayed, and dye pen., zero tolerance. Our shop hired a guy that I worked with about 6 years ago, and he's willing to teach me. And a good friend that I worked with back in 02, is willing to help me out. What's your thoughts, tig or mig. I'm leaning to mig, keep the Millermatic.
For a good proper tig setup your looking at $2500 and then some pricey consumables, you can get a decent mig for $800.
Fit up needs to be bang on. Filling gap with the tig is not fun nor advisable, with mig you can just fill her up. Tig can be incredibly slow and the material needs to super clean to weld properly, Mig you jst crank the volts and burn through.
The versatility and ease of use makes mig the best machine for garage/hobby fab. TIG gives you the ability to execute some stellar welds but the investment of money and patience to learn the skill is not worth it, in my opinion.
There is the new 3 in 1 one machines like the multimatic, Esab rebel or the lincion 210mp, these machines are the cats ass for garage duty. They are all sub $2000 (This is without the tig package) They run on 110 or 220 volts and perform mig/spool gun, stick and are capable of basic DC Tig but are limited to scratch or lift start and don't have quite the adjustable/refinement of a dedicated tig machine.
