I keep looking and then I found the millermatic 180, I keep thinking about the 140 too. So is the millermatic 180 a better deal? I will be welding on older cars and trucks. Maybe build a gokart or something. Or repair junk but I will mostly use it for body work. I am sorry for all the questions, but I have bought the cheaper MIG welders and got dissapointed with them. Luckily I got my money back for them, but I just don't want to go through the dissapointment again. Oh!! Before I forget, I have a cambell hausefield flux-core welder and it welds like sh**. So is the millermatic 180 a smoother flux cored welder? And you can use gas with the flux-cored part on the 180 can't you? Thanks.
