3.11 Short Circuit Protection While Welding
To prolong the useful life of a TIG tungsten electrode, the 202 AC/DC incorporates special circuitry.
In DC LIFT TIG mode, if the tungsten electrode touches the work the welding current is reduced to 40 Amps.
In DC HF TIG mode, if the tungsten electrode touches the work the welding current is reduced to 30 Amps
within 1 second.
In STICK mode, if the electrode touches the work for more than two seconds the welding current is reduced
to 0 Amps.
3.12 Victor Regulator
Pressure regulator (Figure 3-7) attached to the cylinder valve reduce high cylinder pressures to suitable low
working pressures for welding, cutting, and other applications.

WARNING
Use the regulator for the gas and pressure for which it is designed. NEVER alter a regulator for
use with any other gas.
NOTE
Regulators purchased with open 1/8”, 1/4”, 3/8”, or 1/2” NPT ports must be assembled to their
intended system.
1. Note the maximum inlet pressure stamped on the regulator. DO NOT attach the regulator to a system
that has a higher pressure than the maximum rated pressure stamped on the regulator.
