).
NOTE
Operating pressure varies with torch model, oper-
ating amperage, and torch leads length. Refer to
gas pressure settings charts.
Connecting Torch
There are two types of connection for the Torch Leads.
One type uses the Thermal Dynamics ATC connector. The
other uses standard (O2B) connections for gas and cir-
cuitry. Both types may require an adapter kit sold sepa-
rately.
