Displays
• The control panel displays show adjustable operation parameters, their values, and the
units of measure.
• During welding, display P2 shows the welding current value that is currently in use, while
display P6 shows the welding voltage.
Control knobs
• The left-hand control knob P11 allows the adjustment of the speed of wire feeding. The
selected speed is shown on the display on the left-hand side.
• The right-hand side control knob P13 allows for controlling the welding voltage in MIG
and 1-MIG processes, in which case the selected voltage is shown on the right-hand side
display, and the base current in AAA-MIG processes, in which case the adjustment range
is +/- 50.
These control knobs are also used for specifying the operating parameters. A parameter for
adjustment is selected with the left-hand knob, while the value of the parameter is selected
with the right-hand knob.
2.2.2 Adjusting mig dynamics (Arc Force)
When you press button P3, you can adjust the MIG welding dynamics of the machine by
means of the right-hand knob.
When using the MIG or 1-MIG welding process, the welding dynamics setting affects the
features of the welding arc and the amount of welding spatter as shown below:
• The value 0 is the recommended basic setting.
• Use values -1...-9 if you want a softer arc and less spatter.
• Use values 1...9 if you want a rougher and more stable arc. This setting is useful when you
are using 100% CO₂ shielding gas when welding steel.
When using the AAA-MIG process, the welding dynamics setting affects the forming pulse as
shown below:
• Use values -1...-30 if you want a softer arc and smaller penetration.
• Use values 1...30 if you want a rougher and greater penetration.
2.2.3 gas test
The gas test button P4 opens the gas valve without activating the wire feed or power source.
By default, gas flows for 20 seconds. The gas flow time remaining is shown on the display.
The right-hand knob allows you to set the default gas flow time, between 10 and 60 seconds,
and store the new default value in the machine’s memory. To stop the gas test, press the ESC
button.
2.2.4 Wire feed test
When you press the Wire inch button, P6, the wire feeder engine starts but the gas valve does
not open and the power source is not activated.
The wire feed pace is 2 m/min for the first two seconds, and then 10 m/min.
When the button is released, the wire feeding stops. The machine automatically goes back
to the normal state after approximately 3 seconds from release of the button or immediately
when you press the ESC button.
