sorry if this is stupid but i'm about to get a new project and am already thinking about doing airbags this winter...so its a long way off. my room mate is a welder by trade. we got a hobart 140 MIG setup at the house. He tells me it will put it solid welds on anything up to 1/4" thick but is nervous about helping me with the bags. i think he's just being extra mindful because if we did it and my shit broke he'd feel bad or whatever. can anyone that has any experience with doing airbags or anything before give any advice on if the set up we got will work? i mean i trust his professional opinion but at the same time anytime i ask him for help he's weird about being liable for anything that goes wrong. and thats why he's being weird about this working or not. thanks!
