Connection of the MIG/MAG Torch
Connect the welding torch as shown in the picture to the central connection socket, the water connections and
maybe the up/down cable. Observe the colours of the water connections.
Pin assignment of the up / down port, see the schematic.
Connection of shielding gas cylinder
Put the Gas cylinder at the back of the bottle cart and secure it with the chains. Connect cylinder pressure
reducer and check that all connections are tightly sealed. Set the shielding gas flow rate at the pressure reducer
on cylinder (6- 18 l/min). The gas flow rate depends chiefly on the welding amperage.
Connection of work piece cable
When clamping the work piece into its holder, choose an appropriate spot without paint or rust for good
conductivity.
Starting the welding process
Set the MC control box to the MIG/MAG mode, adjust the parameters for the welding job and start welding
process by pressing the torch trigger
MMA welding
Massebuchse
Workpiece socket
+ Buchse Elektrode / WIG
+ socket MMA / TIG
Vorne / front
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 (only MC 1)
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.
