An Auxiliary 115vac Receptacle with Circuit Breaker are included on the back panel of the PRECISION TIG® 225 models. The Canadian (K2533-2) and International (K2534-

1)models are rated 6 amps, while the 208/230/1/60 models (K2533-1 and K2535-1/-2) are rated 20 amps (for use with Lincoln’s 115v SP and Power MIG models).

RECOMMENDED PROCESSES AND EQUIP- MENT

RECOMMENDED PROCESSES

The PRECISION TIG® 225 is recommended for the TIG (GTAW) and Stick (SMAW) welding processes within its out- put capacity range of 5 amps DC or AC to 225 amps AC/DC. It is compatible with most Magnum TIG accessories, as well as many industry standard items, such as TIG torches (adapted for Twist-Mate™), hoses, and water coolers.

The PRECISION TIG® machines are not recommended for arc gouging due to its 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 out- put power coils and rectifiers.

The PRECISION TIG® 225 machine uses Twist-Mate™ output terminals, therefore stud connection adapters (such as LECO. S19257-series) cannot be used for torch connection.

If a PRECISION TIG® 225 is powered from an engine generator which doesn’t 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® 225 is rated at 225 amps, 29 volts, at 10% 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 exceeded, a thermal protector will shut off the output until the machine cools.
