Provides excellent arc starting and stability through- out the machines wide current range (5 to 315 Amps) to handle the vast majority of TIG welding applica- tions.

Simple output current dial allows the user to preset the peak current within the full output range of the machine.

Highly resistant to AC arc rectification.

Thermostatically protected to prevent equipment damage.

No tungsten spitting within current range of electrode.

Designed to make maintenance and servicing easy.

115 Volt Receptacle with 10 Amp Circuit Breaker. Domestic and Canadian Models Only.

220 Volt European (Schuko) type Receptacle with 2 Amp Circuit Breaker. European Model Only.

Low Voltage Trigger Circuit (18 VAC) for maximum operator safety.

Remote Receptacle for Amptrol or Arc Start Switch connection.

Gas Valve Inlet fitting conforms to Compressed Gas Association (CGA) standards.

WELDING CAPABILITY

The Square Wave TIG 275 is rated at 275 amps, 31 volts, at 40% duty cycle on a ten minute basis for DC TIG and AC/DC stick processes. It is capable of high- er duty cycles at lower output currents. If the duty cycle(s) are exceeded, the thermostatic protection will shut off the output until the machine cools to a normal operating temperature.

LIMITATIONS

The Square Wave TIG 275 is not recommended for AC TIG welding when high concentrations of helium gas are used for shielding. This causes starting and arc rectification problems. Also the Square Wave 275 is not recommended for arc gouging due to it's limited output capacity. The Square Wave TIG 275 is also not recommended for pipe thawing.
