Chicago Electric MIG 170 Setting Up The Weld, Do not Switch the Current, While Welding

Setting Up The Weld

1.Make practice welds on pieces of scrap the same thickness as your intended workpiece to practice technique before welding anything of value. Clean the weld surfaces thoroughly with a wire brush or angle grinder; there

must be no rust, paint, oil, or other materials on the weld surfaces, only bare metal.

2.Use clamps (not included) to hold the workpieces in position so that you can concentrate on proper welding technique. The distance

(if any) between the two workpieces must be controlled properly to allow the weld to hold both sides securely while allowing the weld to penetrate fully into the joint. The edges of thicker workpieces may need to be chamfered (or beveled) to allow proper weld penetration.

3.Clamp Ground Cable to bare metal on the workpiece near the weld area, or to metal work bench where the workpiece is clamped.
