Instruction Manual
Mounting the Machine Torch
1. Install the machine torch (with torch leads attached) in the torch mounting bracket without IHS probes
(Fig. 4-21) or the alternate torch mounting bracket (Fig. 4-20) if IHS is used.
2. Position the torch until the torch body extends all the way through the bracket, so that the bracket is now
around the plastic torch sleeve and not touching the stainless steel torch body. Position the torch approximately
.25 " (6 mm) from the workpiece.
3. Tighten the securing screw(s). See Pre-Operation in Section 5 for final adjustment of torch.
Torch Alignment
To guarantee the torch is at right angles to the workpiece, align the torch with a square at 0° and 90°.
See figure 4-21.
