A. Power Switch. When placed in ON position, the white power light will glow indicat-
ing control circuit is energized.
B. Air Test Switch. When placed in TEST position, air filter-regulator can be adjusted
to desired pressure (80 psig / 5.5 bar) before cutting operations. Allow air to flow for
a few minutes. This should remove any condensation that may have accumulated
during shutdown period. Be sure to place switch in OPERATE position before starting
cutting operations.
C. Trigger Lock Switch.
1. Manual Operation using the PT-32EH torch - When placed in LOCK position,
this permits releasing torch switch button after cutting arc has been initiated. To
extinguish arc at end of cut, press and release torch switch button again or pull
torch away from work. When placed in UNLOCK position, torch switch must be
held closed by the operator during the entire cutting operation and then released
at the end of cut.
2. Mechanized Operation using the PT-21AMX torch - In mechanized operation the
Trigger Lock function disabled. Instead, the switch functions as an "Auto-Restrike"
selector. To turn Auto-Restrike "on" (grate cutting), place the switch in the up
position. To turn Auto-Restrike "off" (grate cutting), place the switch in the down
position.
