For rapid re-starts, such as grate or heavy mesh cutting, do not release the
torch switch. In the postflow mode, the arc can be re-started immediately
by depressing the torch switch. This avoids the 2-second preflow portion
of the cutting cycle.

4.3.1. Drag cutting with the pt-32Eh / powercut 875 system
If dragging cutting is desired, attach ESAB's standoff guide (P/N 0558002393).
Then follow steps in Section 4.3. If drag cutting is desired for thin material,
under 9.5mm (3/8"), remove 70 amp nozzle from torch head, insert ESAB's 40
amp nozzle (P/N 0558002908). Lower current level to 40 amps or lower,
(see
Auto Drag Scale on front panel)
. Then follow steps in Section 4.3. Also refer to
PT-32EH Instruction Manual 0558003746.

NOTE:
When replacing the nozzle, always inspect the
electrode for wear. If more than 1.6mm (.06")
of electrode Hafnium has eroded, replace the
electrode. If the electrode is used beyond this
recommended wear limit, damage to the torch
and power source may occur. Nozzle life is also
greatly reduced when using the electrode below
the recommended limit. Refer to Figure 4-3.
