3.2.2 Drag Cutting with the PT-32EH Torch / PowerCut package.
A. LOW CURRENT AUTO-DRAG FEATURE
If drag cutting is desired for thin material under 3/8" (9.5mm) thick, remove
the standard 70 / 90 amp nozzle from the PT-32EH torch and install ESAB's
40 amp nozzle. Lower the current level setting to be within the AUTO-
DRAG range of 20 to 40 amps (see Auto Drag Scale on front panel). Then
follow steps in Section 3.2.1. Also refer to PT-32EH Instruction Manual No.
F-15-747.
B. HIGH CURRENT DRAG CUTTING
If drag cutting is desired on materials above 3/8” (9.5mm) thick, be sure that
the 70 amp / 90 amp nozzle is installed in the PT-32EH torch. Attach ESAB's
stand-off guide and operate as shown in Figure 3.3.
WHEN THE ARC BREAKS
THROUGH THE WORK, BRING
THE TORCH TO AN UPRIGHT PO-
SITION AND PROCEED TO CUT.
TO START A PIERCE, TILT THE TORCH TO
PREVENT MOLTEN MATERIAL FROM COM-
ING BACK AGAINST AND DAMAGING
THE TORCH.

Drag cutting, even with lower current
levels may significantly reduce the life of
torch consumables. Attempting to Drag
Cut with higher currents greater than (40
amps) may cause immediate catastrophic
consumable damage.
