X8 MIG WELDER 2.5 Operation
Figure 38: 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
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 model.
To use gouging, in Control Pad, select Settings > Mode > Gouging.
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
(30V /12 V).
To adjust the welding current while welding, in the Control Pad's Welding view, turn the left knob.
