Inquiry (采购产品): GROB BAND SAW BLADE WELDER I have few problems welding carbon or stainless steel blades. My problem is Bi-metal blades. They break in the weld area or if annealed, will break any where in the anneal area. What am I doing wrong? Do I need to add inert gas around the weld area? Do I need to reduce the amperage?
