I'm after a bigger Mig welder and put a wanted ad in the local free-ads , i've been offered a MaxArc 200 , which from the size he said it was , i presume is oil filled . ( I haven't had a chance to see it yet ) it's cheap ( £50 ) but has a fault , it feeds the wire but doesn't arc . Anyone had any experience with these ? I really want something that will weld 3mm + ( Roll Cage ) but also go low enough for bodywork . Do you think this would fit the bill ? I quite like the idea of an oil cooled one , I presume it's duty cycle would be good ( don't care if it's heavy ( providing we can get in a van ! ) as it will stay in the one workshop . I think it's single or three phase . Any idea what spares availability would be like ?Any help at all would be very much appreciated . Many thanks , regards Al.
