chamfer thick workpieces.
NOTE: Make practice welds on pieces of scrap
the same thickness as your intended workpiece to
practice technique before welding anything of value.
1. 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.

For technical questions, please call 1-888-380-0318.
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.
NOTICE: When welding equipment on a vehicle,
disconnect the vehicle battery power from both the
positive connection and the ground before welding.
This prevents damage to some vehicle electrical
systems and electronics due to the high voltage
and high frequency bursts common in welding.
