RECOMMENDED PROCESSES AND
EQUIPMENT
RECOMMENDED PROCESSES
The Precision TIG 275 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 340 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.
