The PR-2000 can also be fitted with a stitch weld adapter enabling the operator to
lay staggered bead type welds. While rolling the tip on the sheet metal edge, the
welder will automatically deliver an intermittent or pulsating current.
1. Push the Single-Sided weld mode button (fig 6.3). Single Sided Weld Programs
will display on the screen (fig. 6.5). The PR-2000 software defaults to Single Spot
Weld Mode (fig. 6.6).
2. Select Stitch Welding Program by pressing the Left or Right Navigatioin
Buttons (fig. 4.9). Make sure that Stitch Welding graphic appears on the screen
(fig. 6.31)
3. Choose weld power level by pressing the "Next Program" button repeatedly.
(refer to section 4.6 "Setting the weld program").
4. Fit Single-Sided gun with the stitch electrode (fig. 6.33).
5. Prepare the surface area by removing paint and primer.
6. Ground the working area (refer to section 6.1 "Single-Sided Welding
Overview").
7. Roll the tip on the sheet metal edge while keeping the trigger depressed. The
welder will automatically deliver an intermittent or pulsating current.
8. Repeat as needed.
This procedure works well on stainless steel, and therefore lends itself well to rust
repair and patching. It's easy to use and can be manipulated to fit any shape or
form you require.
Tip: You can use stitch electrode to weld pulling tabs onto areas that
need to be pulled.
