WARNING
This torch is not to be used with oxygen (O
2
).
NOTE
Operating pressure varies with torch model and
operating amperage. Refer to gas pressure settings
chart for each model.
G. Direct Contact Hazard
For exposed tip the recommended standoff is 1/8" - 1/4" (3 - 6.4
mm).
H. Parts-In-Place (PIP) Circuit - 12 vdc
The torch and leads include circuitry called Parts-In-Place
(PIP). This circuit includes a switch located at the torch
head. The shield cup closes this switch when properly
installed. The torch will not operate if this switch is open.
