Control Panel
1.
Pre flow gas timer control. This is the time the gas will flow prior to welding to purge the torch gas line.
Adjustment 0-2Second
2.
Welding current adjustment (peak current when in pulse mode) Adjustment 10-185A
3.
Base current adjustment during pulse mode. Adjustment 20-90%. For example at a peak current of 100A
and base current set at 30% means the welding current will go from 100A to 30A during each pulse cycle
4.
Downslope timer control.This is the time the current will take to reduce at the end of the weld. This helps
eliminate craters or pin holes forming. Adjustment 0-10 Seconds
5.
Arc force control. This provides adjustment of the short circuit current during MMA welding. The control
helps prevent electrode sticking. The higher the setting the more forceful the arc.
6.
Pulse frequency control. This control allows the setting of the pulse frequency (pulses per second) when in
the pulse welding mode. Adjustment 0.5-300 Hz.
7.
Pulse duty control. This control sets the time the peak current will be on during each pulse. For example at
a peak current of 100A and base current set at 30% means the welding current will go from 100A to 30A
during each pulse cycle. With the pulse duty set at 60% this means that 60% of the pulse time will be at
100A and 40% of the pulse time will be at 30%. Adjustment 10-90%
8.
Cleaning control (AC mode). When welding materials with a refractory oxide surface such as aluminium
this oxide needs to be removed to allow welding of the base material. In the AC mode the oxide is
removed during the positive half of the AC wave. This control allows setting of the amount of time between
positive and negative. The control can set the amount of time in the positive (cleaning time) of the cycle.
The higher the setting the more
aggressive the cleaning action but more time in the positive cycle drives
more energy into the tungsten so care should be taken to avoid overheating the tungsten. Adjustment
20-80%
9.
Post gas timer control. This controls the time the gas will flow after the arc is extinguished. This gas flow
time protects the weld zone and electrode from contamination during cooling. Adjustment 0-10 seconds
