Am curious if anyone could give me abit of advice. Am planning on getting an engine driven welder. Am doing moderate on site stick welding where there usually is no power, plus can use the gen. For running an assortment of tools. Other than that, I plan to do abit of tig welding with it also. Is there a big difference between the tig capabilities on the bobcat 250 and the trailblazer 275/325? Not concerned with a/c or aluminum welding, but the difference in price between the bobcat and trailblazer, I could get a few nice accessories, and or a new Tig setup. In the end, its probably a judgement call with which one will work best, but would appreciate some advice. Thanks.
