Advanced Features

Powerful output - 400A@100% Duty cycle.

Advanced Pulse control - Minimize heat input on thin materials, and provide for a faster freezing weld puddle for uphill welding on curved surfaces such as process piping. The TIG pulse also helps moderate filler metal deposition for consistent bead appearance.

High-frequency start - Makes it easy to establish an arc under a variety of conditions.

Fast Spot Arc system - Simply controls the spot arc parameter and offers a stable arc.

Fast, precise, clean arc ignition and arc ending.

10 channels memory capacity.

Powerful and Reliable at heavy industrial level

This unit is a 3-phase TIG welder equipped with latest IGBT modules, which ensures a powerful output 500A@100% duty cycle. It is also equipped with an integral cooling unit, providing efficient cooling for liquid-cooled torches in high duty production welding environments. With the shape of the arc, weld penetration, cleaning effect, as well as the other features are under precise control, and ensuring that the quality of the welds remains high at every level.

Pulse TIG

Conventional Pulsed TIG

High Speed Pulsed TIG

Typically from 0.2 to 10 PPS. Provides a heating and cooling effect on the weld puddle and can reduce distortion by lowering the average amperage. This heating and cooling effect also produces a distinct ripple pattern in the weld bead. The relationship between pulse frequency and travel speed determines the distance between the ripples. Slow pulsing can also be coordinated with filler metal addition and can increase overall control of the weld puddle.

In excess of 40 PPS, Pulsed TIG becomes more audible than visible—causing increased puddle agitation for a better as-welded microstructure. Pulsing the weld current at high speeds — between a high Peak and a low Background amperage — can also constrict and focus the arc. This results in maximum arc stability, increased penetration and increased travel speeds.
