MMA welding

To use X8 MIG Welder in MMA mode, in Control Pad:

Select Settings > Mode > MMA.

Select the MMA welding program. An all-around MMA welding program pre-installed.

X8 MIG Welder features a 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). If the VRD is in use, it keeps the open circuit voltage on a lower, pre-set level (20 V/12 V).

For MMA welding, both DC+ and DC- mode are available.

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.

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.
