1.4 Overview of Machine

1. Power switch
The power switch disconnects the internal electronic circuitry from the welding supply voltage.
NOTE! The welding cables will still be live if the power source is switched on.
2. Power indicator
The power indicator will illuminate green when the power is switched on. If the power indicator illuminates
red then the welding input cables are incorrectly connected and should be reversed. No damage will be
caused if the power cables are incorrectly connected but the unit will not work.
3. Latch switch
The latch switch switches between the two different torch switch modes. In the off position the torch switch
must be pressed and held during welding. In the on position the torch switch may be pressed and released
during welding. To stop welding the torch switch must then be pressed and released again.
4. Flow meter
The flow meter gives an indication of gas flow and allows the gas flow rate to be adjusted from the front
panel of the unit.
NOTE! Do not over tighten the control knob as damage may occur to the flow-meter valve seat, note
that if the control knob is unscrewed too far air may enter the valve assembly and may cause porosity or
contamination of the weld.
