<div>I have an Longevity 250 stick welder that has been pretty reliable and works on single phase 240v. I did have a situation where it would power up but not weld after just sitting around for awhile. I took the cover off and found that the standoffs for the circuit board had crumbled…I replaced then and it started welding perfectly again. </div><div><br></div><div>I am looking at the Everlast 255EXT for a tig welder which is also a 240v single phase unit. I will also say that I find acetylene gas welding indispensable in some circumstances. </div><div><br></div><div>Jon</div><div><br></div><div><br></div><div><br></div>

The multimatic claims to handle up to 3/8" material at its limited duty cycle. For the amount of time I would ever need to weld thicker material, I figure I could farm out those jobs. I wouldn't be comfortable doing my own pressure boundary welds in any case. I'm a designer, not a craftsman, and that seems like an appropriate time to engage a professional.
