MMA WELDING

MMA process not available with robot mode activated.
KINGSTAR range power sources are able to manage the MMA process in DC mode. This welding machine is suitable
for welding all types of electrodes, with the exception of cellulosic (AWS 6010).
- Make sure that the Power On switch is in position 0 (OFF), then connect the welding cables, respecting the polarity
required by the manufacturer
workpiece is at the closest point to the weld, ensuring that the electrical contact is good.
- Do not touch the torch or the electrode holder and the earth clamp simultaneously.
- Turn on the machine using the Power On switch.
- Select MMA process.
- Adjust the current based on the electrode diameter, welding position and type of weld to be made.
- After welding, always switch off the power source by removing the electrode from the electrode holder.
Beware of electrical shocks
When the main switch is in ON position, the electrode and the non-insulated part of the electrode holder are live.
Therefore, make sure that the electrode and the non-insulated part of the electrode holder do not come into contact
with electrically conductive or earthed persons or components (e.g. outer casing, etc.).
The MMA process is not available when robot mode is activated.

MMA process parameters

Description
Hot Start Improves ignition even when using electrodes with
poor ignition properties
Arc Force� 0 voltaic arc with little spatter, barely defined
100 voltaic arc with spatter, but stable
Hot start time. To be adjusted according to the diameter of
the electrode to be welded.
Antistick. Function that prevents the electrode from bonding
to the workpiece
Cut off Voltage. Arc cut-off voltage Once the set voltage is
reached, the arc is extinguished, avoiding optical flashes and
preserving the electrode for subsequent ignitions.
