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

Figure 3-6. Electrode Wear Limit
NOTE: When replacing the nozzle, always inspect the electrode for wear.
If more than 1.6 mm (.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 exploded view of PT-32EH torch.
3.3.1. Drag Cutting with PT-32EH torch / PowerCut 1500 package.
LOW CURRENT AUTO-DRAG FEATURE
If drag cutting is desired for thin material under 9.5 mm (3/8") thick, remove
the standard 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 "Cutting with the PowerCut-1500" section. Also refer
to PT-32EH Instruction Manual No. F15-440.
HIGH CURRENT DRAG CUTTING
If drag cutting is desired on materials above 9.5 mm (3/8") thick, be sure that
the 90 amp nozzle is installed in the PT-32EH torch. Attach ESAB's stand-
off guide and operate per heat shield guard installation and operation figure.
