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.
4. Set the Wire Speed Dial and the Current Switches to
the desired settings.
Refer to the chart on the welder or the chart on the
previous page.
DO NOT SWITCH THE CURRENT
