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.
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.
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. Turn the Power Switch to the OFF position,
then plug the Power Cord into a properly
grounded, GFCI protected 120 V AC (20 amp
rated) or 240 V AC receptacle that matches
the plug. The circuit must be equipped with
delayed action-type circuit breaker or fuses.
