Micro pulse ac/dc tig weld for professional welding MASTERTIG 250AC

AC Frequency control

control 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.

AC Balance Control

Controls arc cleaning action. Adjusting the % EN of the AC wave controls the width of the etchingzone 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.

Independent AC Amperage Control

Controls arc cleaning action. Adjusting the % EN of the AC wave controls the width of Allows the EN and EP amperage values to be set independently. Adjusts the ratio of EN to EP amperage to precisely control heat input to the work and the electrode. EN amperage controls the level of penetration, while EP amperage dramatically effects the arc cleaning action along with the AC Balance control.
