Weld-on nuts are common throughout the car body for attachments of interior, tail
lights, door moldings, etc. and are applied with ease using the PR-2000.
Tip: Different size nuts are available from your local Pro Spot distributor
or on the web at Pro Spot online store.
Nuts are held in place during welding with a shrinking electrode.

will display on the screen (fig. 6.5). The PR-2000 software defaults to Single Spot
Weld Mode (fig. 6.6).
2. Select Nut Welding Program by pressing the Left or Right Navigatioin Buttons
(fig. 4.9). Make sure that Nut Welding graphic appears on the screen (fig. 6.13)

(refer to section 4.6 "Setting the weld program").
4. Fit Single-Sided gun with the Shrink Electrode (fig. 6.15).
5. Prepare the surface area by removing paint and primer.
6. Ground the working area (refer to section 6.1 "Single-Sided Welding
Overview").

pressure and push the trigger to weld.
8. Repeat as needed.
Spot hammer dent pulling is used to repair dents on a vehicle body. The spot
hammer welds directly onto the work area and pulls the dent.
Tip: The replaceable welding tip should last for over one thousand welds.
