RECOMMENDED PROCESSES AND EQUIPMENT

RECOMMENDED PROCESSES

The Precision TIG 375 is recommended for the TIG (GTAW) and Stick (SMAW) welding processes within its output capacity range of 2 amps DC, or 5 amps AC, to 420 amps AC/DC. It is compatible with most Magnum TIG accessories (refer Equipment Limitations), as well as many industry standard items, such as TIG torches, hoses, and water coolers.

PROCESS LIMITATIONS

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 electrical ratings and duty cycles, per the Specifications Section A-1, A-2, with Thermostat protection of the primary and secondary transformer coils.

The Precision TIG machines do not have Hi-Frequency available at the Stick electrode stud, therefore stud connection adapters (such as LECO. S19257-series) cannot be used for torch connection.
