More Information

When it’s time for thicker materials and heavier jobs, choose the Precision TIG® 375, which provides for the highest duty cycle in its class. The Precision TIG 375 also features a built-in TIG pulser, that can be activated to help control heat input in the weld and reduce distortion and burn-through on thin materials.The Precision TIG 375 features the patented Micro-Start™ II Technology, which enhances starting and arc stability, and provides for more precise welds and crater fills.



Simplicity through technology

AC Auto Balance® automatically provides for the optimal mix of cleaning and penetration for welding on Aluminum. Or, take full control – adjust the AC Balance® to increase or decrease cleaning action or penetration on aluminum

Advanced Pulse Control panel (Standard on the Precision TIG 375)

Enable the TIG pulser to minimize material distortion from excessive heat input. The TIG pulser can also help moderate filler metal deposition for consistent bead appearance.

Wide output range

Tackle either end of the material thickness spectrum with an amperage range of 2 to 420 amps

Side-mounted torch holder and connections

Enables simple cable management and protection, and a place for your torch when not in use.
