RECOMMENDED PROCESSES AND EQUIPMENT
RECOMMENDED PROCESSES
The PRECISION TIG 185 is recommended for the TIG (GTAW) and Stick (SMAW) welding processes within its output capacity range of 5 amps DC,or 7 amps AC, to 185 amps AC/DC. It is compatible with most Magnum TIG accessories, as well as many industry standard items, such as TIG torches (adapted for
PROCESS LIMITATIONS
The PRECISION TIG machines are not recommended for arc gouging due to it's limited output capacity, and are also not recommended for pipe thawing.

EQUIPMENT LIMITATIONS
The PRECISION TIG machines are protected from over loads beyond the output ratings and duty cycles, per the Specifications in the Installation Section, with Thermostat protection of the output power coils and rectifiers.
The PRECISION TIG 185 machine uses
If a PRECISION Tig 185 is powered from an engine generator which doesnʼt have sufficient capacity, the AC Balance control and the Output control will not provide full range of control.
WELDING CAPABILITY(Duty Cycle)
The PRECISION TIG 185 is rated at 185 amps, 27 volts, at 15% duty cycle on a ten minute basis. It is capable of higher duty cycles at lower output currents. See rated output graph, on specification sheet located in the Installation Section. If the duty cycle is exceed- ed, a thermal protector will shut off the output until the machine cools.
