Pin Welding:

1.
Pin welding is generally used when welding small dents. Thinner Pins require
less weld time than thicker Pins. When inserting a Pin (not included) into a
Nozzle (3A, 5A), make sure the Pin size is the same as the Nozzle (i.e., 2mm Pin
for a 2mm Nozzle).
2.
The Pins are pressed into place while they are being welded. Also, the Pins
should be pulled using an appropriate pulling device (not included).

Tempering:

1.
Thoroughly clean the welding area, removing all paint, rust, dirt, etc. to ensure
proper conduction.
2.
Connect the Ground Clamp (14) as close as possible to the welding area.
(See Assy. Diagram.)
3.
Set the Time Mode Selector (8) to "CONTINUOUS". (See Figure F.)
4.
Turn the Power Potentiometer Knob (6) to "
5.
If the dent is over stretched or uneven, use a Carbon Electrode (9A) to contact
the area, moving the Carbon Electrode from side to side to heat the area.
6.
Use a clean, wet towel to cool the welding area for partial tempering. To avoid
accidental burns, always wear fire retardant gloves during this process (Be aware
of hot steam). Also make sure the towel does not dry out, creating a fire hazard.

Flat Shrink Tip Welding:

1.
Firmly place the Welding Gun, with the Shrinking Electrode (1A) installed with its
rounded end facing out, against the workpiece. (See Accessories List.)
2.
Turn the Power Potentiometer Knob (6) to its "Shrink" setting and time.
(See Figure F.)
3.
NOTE: The shrinking time required is determined by the thickness of the metal
and the type of metal. If the unit does not shrink properly on the first attempt, a
slightly longer time may be needed.
