You can adjust the following parameters through
Settings
>
Parameters
:
• Welding current
• Dynamics: adjusts the short circuit behaviour. On the minus side, the arc is softer (less spatter). On the
plus side, the arc is harder (the arc is more stable).
• StartPower: Adjusts the power level for arc ignition. You can use this parameter to give extra power or less
power for the arc ignition.
Gouging
8
Carbon-arc gouging refers to a method where metal is removed by melting it with a welding arc and blowing
the melted metal away with compressed air. Carbon-arc gouging can be used with the majority of metals,
such as steel, stainless steel, cast iron, nickel, copper, magnesium and aluminium. The equipment used in
carbon-arc gouging comprises the power source, a carbon holder and its cables, and the gouging carbon.
Also a sufficient compressed air supply must be available.
The gouging (carbon arc gouging) functionality is available in the 500A and 600A models.
To use gouging, in Control Pad, select

Note:
X8 MIG Welder features an integrated voltage reduction device (VRD). When the welding machine
is on but the welding arc is not ignited, the welding machine is on open circuit voltage (50 V). When
the VRD is in use, it keeps the open circuit voltage on a pre-set level (20V /12 V).
To adjust the welding current while welding, in the Control Pad's
Welding
view, turn the left knob.
To adjust the dynamics while welding, in the Control Pad's
Welding
view, turn the right knob.
