SECTION 5
WARNING

5.0 General

A. Periodically check torch head assembly. Replace if worn or damaged.
B. Torch cable should be inspected periodically. If there are any cuts through the protective sheath or wire
insulation, replace the cable.
5.1 Dirt or Contamination
Dirt or other contamination in the torch and loose consumable parts can cause premature failure of the PT-38
Torch through internal arcing. To avoid this, users are instructed to do the following: Ensure that clean, dry, and
oil-free air is being used. Wipe the retaining cup clean with a cloth before installing each fresh set of consum-
ables. The ability of the retaining cup to resist arc tracking over its surface is reduced when dirt or other contami-
nation is allowed to collect there.
BEFORE ANY MAINTENANCE IS ATTEMPTED ON THIS TORCH, MAKE
SURE THE POWER SWITCH ON THE CONSOLE IS IN THE "OFF" POSI-
TION AND THE PRIMARY INPUT IS DEENERGIZED.
