Gouging - Kemppi X8 MIG Welder Operating Manual

Figure: MMA Welding View
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

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 com-
prises 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 Settings > Mode > Gouging.
X8 MIG Welder features an integrated voltage reduction device (VRD). When the welding machine is on but the weld-
ing 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.
