TIG Welders

TIG (tungsten inert gas) welding or gas tungsten arc welding (GTAW) uses a constant current (CC) welding power supply to generate an electric arc between a non-consumable tungsten electrode and the workpiece, creating heat that is applied to produce a weld. The weld area is typically protected from atmospheric contamination by use of an inert shielding or cover gas of argon or helium.

Tackle Different Challenges on the Jobsite With a Welder/Generator

Wasted time and lost productivity are enemies in any welding operation, especially in harsh conditions, on large jobsites or in applications where it’s difficult for operators to get to where the work must be done. The right welder/generator system, equipped with advanced technologies, can help complete work faster while also improving quality and safety.

What You Need to Know About Weld Anatomy and Joint Geometry

Are you wasting lots of time and money on welds that are larger than they need to be, particularly on thicker materials? Or dealing with inconsistent quality or increased crack sensitivity due to welds with improper dimensions? There are many different ways to design welds that strike the best balance between weld quality and productivity.

Switching Polarity in Welding Applications

When competing for time-critical jobs, saving even a few minutes with each changeover can make a significant difference and reduce operator exposure to trip and fall hazards. Investing in technology that allows welders to easily change processes with the push of a button at the weld joint can save substantial time, increase weld quality and improve operator safety.
