3.2. Installation for MMA Welding
•
3.2.1. Set up installation for MMA Welding
Connection of Output Cables
Two sockets are available on this welding machine. For MMA welding the electrode holder is
shown be connected to the positive socket, while the earth lead (work piece) is connected to the
negative socket, this is known as DCEP. However various electrodes require a different polarity for
optimum results and careful attention should be paid to the polarity, refer to the electrode
manufacturers information for the correct polarity.
DCEP: Electrode connected to “+” output socket.
DCEN: Electrode connected to “-“ output socket.
