OPERATION
TO PREVENT SERIOUS INJURY AND ELECTRIC SHOCK: Never touch the Upper
and Lower Tongs when welding a work piece. Allow the Electrode Tips and the work
piece to cool before handling.
1. Ensure that materials to be welded are free from scale, oxides, paint, grease, and oil.
2. The Operating Lever allows opening and closing of the Upper and Lower Tongs.
3. To begin welding process, push down on the Operating Lever to close the Tongs and compress the
work pieces between the Electrode Tips. Ensure there are no gaps between the work pieces as this will
weaken the weld.
4. Push and hold the Power Switch sideways in either direction to apply electric current. Release the
Power Switch to shut off current and stop the welding process.
5. When alignment is complete re-tighten the Cap Screws.
NOTE: The spot welding time is determined by the thickness of the work pieces, the type of metals, and
the skill of the operator.
Avoid damage to the Welder by not welding for more than the
prescribed duty cycle time. This Welder has a 50% duty cycle
at rated output (2.5 kV A) based on a 10 second time period,
meaning unit can weld for 5 seconds out of each 10 second time
interval without overheating. Failure to carefully observe duty cycle
limitations can easily over-stress a welder’s power generation
system contributing to premature welder failure.
ADJUSTING TONG AND LEVER PRESSURE
REPLACING ELECTRODE TIPS
1. Used Electrode Tips that cannot be restored to a suitable
condition by dressing will need to be replaced.
2. To replace Electrode Tips, remove used Tips from the
Upper and Lower Tongs.
3. To attach new Electrode Tips to the Upper and Lower
Tongs, coat Tip threads with heat sink compound (not
included) and screw the Tips onto the Tongs, Do not over
tighten.
