[QUOTE=old51sedan;8014860]Thinking of buying a mig welder to fill several holes that have been drilled in the box of my truck by PO over the years. In talking with my buddy who owns a body shop, he tells me not to buy one that uses flux. He says the flux will pop through bondo if it next to it. Has anyone had this problem? I'm not sure what to buy now, I'd like something that runs on 120 volt.[/QUOTE

All I can offer is having welded and will be welding today with a mig welder near bondo, the bondo does melt/pop when you weld, but I was told it's the heat of the welding.
