NOTE: Duty Cycle is the percentage of 10 minutes the welder can be in operation
without overheating. 15% duty cycle means that the welder can be energized
approximately 1-½ minutes out of each 10 minute period. 40% duty cycle means the welder
can be energized approx. 4 minutes out of each 10 minute period.
Control Panel
1. Function Selector (1):
a) Continuous Operation is used for Carbon warming
and tempering of work material.
b) Timed Operation is used for washer or needle
welding.
c) OFF to turn off power supply to welder.
2. Timer Control (2): Sets the duration of the pulse
during timed welding operation. Settings range from 0
to 1.2 seconds.
3. Power light (3): indicates that power is supplied to
the welder.
4. Thermostat light (4): comes on if overheat cutoff
function is active.
5. Working light (5): indicates that welding operation is in process.
Installing the Welding Tip
Various tips are supplied for different welding operations. Select and install the appropriate tip before
beginning work. WARNING: The welder must be OFF and UNPLUGGED when installing tips.
1. Insert the butt end of the tip into the Welding Gun. Be sure the welding tip is rmly seated in the gun.
2. Rotate the collar of the gun clockwise to tighten the tip.
Welding Tip Selection:
1. Electrode with magnet for washer: Washer can be held in magnetic tip, to be spot welded to dented
area. Washer will later be pulled to pull out dent.
2. Washer electrode reversed for shrinking: Magnetic washer electrode may be reversed in the gun and
used for shrinking. A convex dented area can be heated, then cooled with a wet rag to shrink the
metal and reduce the swelling.
3. Carbon Electrode: May be used for cutting, filling cracks or heating for tempering or shrinking.
4. Spot Weld Needle tips: Used for spot welding.
Duty Cycle
This welder is rated for 15% duty cycle during welding at maximum power and 40% during warming
at minimum power. Do not exceed duty cycle limits, as that may overheat the machine causing
damage or premature wear. If the welder overheats, the Thermostat Light will come on, the welder
will automatically shut off, and must remain off at least 30 minutes until cool.
