Using the Shrinking Electrode

1. Insert the Magnetic / Shrinking Electrode in the Gun with the rounded Shrinking end protruding.

2. Set the Ground Clamp as close as possible to the damaged area.

3. Set the Function Selector to CONTINUOUS.

4. Place the Electrode on the damaged area and squeeze the trigger. The electrode will heat up, as

will the work material. Use the electrode to press the heated material down into shape, reducing or

“shrinking” convex dents.

CAUTION: Be aware of your working time and do not exceed the welder’s Duty Cycle.

Using the Carbon Electrodes

The Carbon Electrodes can be used for warming or tempering, spot welding sheets together, crack

ﬁlling or cutting sheet metal.

CAUTION: Be aware of your working time and do not exceed the welder’s Duty Cycle.

For Warming:

1. Insert the carbon electrode into the gun and tighten into place.

2. Connect the Ground near the work area.

3. Set the Function Selector to the “CONTINUOUS” setting.

4. Contact the metal with the electrode, holding the trigger down, and moving the electrode continu-

ously over the surface.

5. When the surface has been heated, release the trigger and remove the electrode from the metal.

6. Warming the metal will anneal it, causing it to become softer. Sudden cooling of annealed metal,

such as by applying water will temper the metal, causing it to become harder.

7. Depending on your reason for heating the area, you may hammer the annealed area to shape it, or ap-

ply a wet rag to the surface to temper the metal. Repeat the heating and working process as needed.

Spot Welding:

1. Using the Carbon Electrode, set the Function switch to “CONTINUOUS”.

2. Clamp the new sheet of metal to the car body.

3. Attach the ground nearby the work location.

4. Contact the electrode to the car body NOT the patch material, and squeeze the trigger. Hold the

trigger in the ON position while the metal heats up. When you observe the metal beginning to fuse,

either remove the electrode from the metal, making a spot weld, or move the electrode to make a

line weld.

Crack Filling:

1. Using the Carbon Electrode, set the Function switch to “CONTINUOUS”.

2. Insert a clean piece of steel wire into the crack which has been cleaned and prepared for welding.

3. Attach the ground nearby the work location.

4. Contact the electrode to the metal and squeeze the trigger. Hold the trigger in the ON position while

the metal heats up. When you observe the wire beginning to fuse, move the electrode along the

crack to fuse the wire with the metal, ﬁlling the crack.
