TIG Welding Machine

INTRODUCTION 

Control the width of the arc cone. Increasing the AC Frequency provides a more focused arc with increased directional 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.
