Skill level is not a problem. I have experience in building boiler parts, mainly .035 stainless tubing to 3/8 inch black iron plate, with the TIG process. The thing of it is, I was using a Lincoln Square Wave TIG 355. Now I own my own business and don't have access to that machine. The machine I will be using is my field service rig's TIG unit. The reason being, I do proto type project welding for an engineering business, on occasion, that is out of my home state. Well, this project has me traveling some 300 miles to do this project. The reason being, they don't have any welding machines. GOOD MONEY for me to do it!! So, I will be using my Miller Trailblazer 251nt. Park the truck outside, fire it up, and drag my TIG welding stuff into the shop. I love this 3 phase machine, and that's what I'm stuck with because I'll be nowhere near my shop. Duty cycle is not a problem, as it is 100% at 250 amps, and I think it is safe to say that I won't be welding that high on .035 material. Fitup WILL be tight and consistent, as the joints will be end milled. Thanks for your response.
