9 MMA DC WELDING
SYNSTAR 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 of the electrodes that you will be using and the terminal of the earth cable
to the 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.).

Hot Start
This is the overvoltage supplied when the arc is ignited.
This is adjustable from 0 to 100% of the set welding
current.

poor ignition properties
Arc Force
This regulates the dynamic characteristics of the arc.
This is adjustable from 0 to 100% of the set welding
current.

Hot start time
This is the overvoltage time supplied when the arc is
struck. Adjustment ranges from 0 to 1 sec.
To be adjusted according to the diameter of the
electrode to be welded.
Antistick
The Antistick function automatically turns off the
welding power source when the electrode sticks to
the material to be welded, allowing removal by hand
without spoiling the electrode holder.
