Description
Arc Force (MMA)
This is a feature used in Stick welding. Arc force is a temporary increase of the output current during welding when the arc is too short. This feature supports operators to achieve consistently excellent arc performance resulting faster & better quality production.
Hot start (MMA)
There is a temporary increase of the output current (0.5 seconds approx.) during the start of welding. Hot Start provides excellent arc ignition without the electrode sticking.
Adjustable Current Down-slope time (Crater fill in TIG Welding)
Downslope time adjustable from 0.5 to 2.3 seconds. It supports to fill the crater.
Electric shock prevention switch
This feature is very useful in the wet environment, high altitude, narrow places, welding inside metal containers. When the anti-shock function is used, the output voltage is about 13V at no-load.
Input voltage abnormal indicator
When the input voltage is abnormal; over-voltage or under-voltage, the light gets on and the machine has no output. When one phase is missing, the voltage abnormal indicator flashes twice in every second.
