Setting Up the Weld
Make practice welds on pieces of scrap
1.
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
Switch to the desired settings.
Refer to the chart on the welder or the
chart on the facing page.
