Hi, Been given a Cebora 130 turbo to learn to weld with. Are they any good. I want to weld on cars and to make some gates from box section, mainly 3mm. Occasionally small amounts of thicker stuff... Is it worth persevering with my set or should I upgrade. If so what do you suggest. If I upgrade will that held my welding or just give more umph! Thanks PS I am on single phase, 32a supply.
