1. Power On/Off
This light illuminates when the power source is on.
2. 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 .
3. Welding Mode Switch
With two positions, controls the welding mode of the machine: one
for Stick welding and one for TIG welding.
SMAW
When the mode switch is in the TIG position, the stick welding
functions is disabled and the machine is ready for TIG welding.
4. Output Current Knob
Potentiometer used to set the output current used during welding.
5. Positive Quick Disconnect
Positive output connector for the welding circuit.
6. Negative Quick Disconnect
Negative output connector for the welding circuit.
7. Power Switch
It turns ON/OFF the input power to the machine.
8. Input Cable
The machines are provided with a plugged input cord. Connect it
to the mains.

Auto Adaptive Arc Force (with stick welding)
The arc force function is activated during stick welding. This
function increases temporary the output current, used to clear
intermittent connections between the electrode and the weld
puddle that occur during stick welding.
This is an active control feature that guarantees the best
arrangement between the arc stability and spatter presence. The
control determines the amount of current to apply to break the
metal drop that is being transferred from the electrode to the work
piece to guarantee the arc stability, but not too high to minimize
spatter around the welding puddle. That means:
• Electrode/work piece sticking prevention, also with low current
values
• Spatters reduction
The welding operations are simplified and the welded joints looks
better, also brush before welding for better results.
With the Stick welding are also enabled the following features:
• Hot Start: This is a temporary increase in the initial welding
current. This helps ignite the arc quickly and reliably.
• Anti-Sticking: This is a function that decreases the output
current of the machine to a low level when the operator makes
an error and sticks the electrode to the work piece. This decrease
the current allows the operator to remove the electrode from the
electrode holder without creating large sparks that can damage
the electrode holder.
