Unique MIX TIG
Everybody knows the AC current has a good clearance and DC current gets a good penetration. What if mix the AC and DC?
MIX TIG is TOPWELL’s unique technology, it contains AC current and DC current in one duty cycle.
That keeps the advantages and reduces disadvantages from each other. Using the MIX TIG technology gets an excellent arc concentration and can be carried out the excellent welding performance, especially for thick plates.

14. Function Sequence
Controls the width of the arc cone. Increasing the AC Frequency provides a more focused arc with increased directional control.
Note: Decreasing the AC Frequency softens the arc and broadens the weld puddle for a wider weld bead.
Controls arc cleaning action. Adjusting the % EN of the AC wave controls the width of the etching zone surrounding the weld.
Note: Set the AC Balance control for adequate arc cleaning action at the sides and in front of the weld puddle. AC Balance should be fine tuned according to how heavy or thick the oxides are.
Adjusts the ratio of EN to EP amperage to precisely control heat input to the work and the electrode.
Note: EN amperage controls the level of penetration, while EP amperage dramatically effects the arc cleaning action along with the AC Balance control.
This unit is a 3-phase TIG welder equipped with latest IGBT modules. 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.
The maximum output is up to 500A. It’s capable to welding thin metal fast and thick metal continuously.
Mild steel 12mm V groove, 5 layers
Layer 1: 300A， Layer 2: 300A，Layer 3: 280A，
