Connection of the MMA holder
Connect the electrode holder as shown in the picture to the positive terminal.
Here, however, always follow the polarity specification of the electrode manufacturer.
Wire feed unit with control cable must be connected into the machine.
Connection of work piece cable
When clamping the work piece into its holder, choose an appropriate spot without paint or rust for good
conductivity.
Potentiometer for welding current control enable
To be able to regulate the welding current with a potentiometer in MMA mode, it must be connected as shown in
the picture below or see circuit diagram at the 17-pole remote control socket.
Further must be called in MIG mode the control function Fx, and under Point ‚remote control EC 1’ the parameter
‚Curr - CAn’ must be adjusted.
Starting the welding process
Set the MC control box to the MMA mode, adjust the parameters for the welding job and start the welding
process by tipping the electrode on the work piece.
Adjust Hotstart and Arcforce
To get a better start of the welding process, it is possible to adjust the Hotstart current (tap the button Fx)
between 0% (no Hotstart) to 150% of the welding current. The Hotstart time is fixed to 1 second.
With the parameter Arcforce it is possible to minimize the risk of sticking.
When the electrode sticks in the welding seam, the electrode will be burn free with short current pulses.
For Cell electrodes a value greater than 200% is recommended.
