Output Connections and Front Panel Controls
A quick disconnect system using Twist-Mate
connections. Refer to the following sections for more information on connecting the machine for
operation of stick welding (MMA) or TIG welding.

(+) Positive Quick Disconnect: Positive output connector for the welding circuit.

(-) Negative Quick Disconnect: Negative output connector for the welding circuit.
1 – Carrying handle, 2 – Power ON/OFF LED, 3 – Thermal LED, 4 – Positive output,
5 – Negative output, 6 – Output current control, 7- TIG Lift/Stick switch, 8 – ON/OFF Switch
Output Current Knob: Potentiometer used to set the output current used during
welding.
Power ON/OFF LED: This LED lights up when the machine is ON.
Thermal LED: This indicator will turn on when the machine is overheated and the
output has been disabled. This normally occurs when the duty cycle of the machine
has been exceeded. Leave the machine on to allow the internal components to
cool. When the indicator turns off, normal operation is again possible.
With the MMA welding there are available following features:
Arc Force. During MMA welding is activated the function Auto Adaptive Arc Force that increases
temporary the output current, used to clear intermittent connections between the electrode and the
weld puddle that occur during stick welding. The feature "Auto Adaptive Arc Force" has instead of a
fixed or manual regulation, an automatic and multilevel setting: its intensity depends by the output
voltage and it is calculated in real time by the microprocessor where are also mapped the Arc Force
levels. The control measure in each instant the output voltage and it determines the amount of the
