Arc forcePress the arc force button and you will see the numerical value corresponding to the dynamics onthe display. You can change the value by turning the pulse potentiometer. If numerical value isadjusted negative (-1...9), the arc is softened. The amount of spatter decreases when welding atthe upper end of the recommended current range of the electrode. On the positive side (1...9) thearc is rough. In TIG mode pedal max. and min. current can be selected.6. Hot startBy pressing hot start button you will see the numerical value corresponding to the hot start pulse onthe display. You can change the value by turning the potentiometer. In TIG mode gas test functioncan be selected.56798410 111613 14151217
