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.
(1) Connect the earth lead to “-”, tighten clockwise;
(2) Connect the earth clamp to the work piece. Contact with the work piece must be firm contact
with clean, bare metal, with no corrosion, paint or scale at the contact point.
(3) Connect the electrode lead to “+”, tighten clockwise;
(4) Each machine is equipped with a power cable should be based on the input voltage welding
power cable connected to the appropriate position, not to pick the wrong voltage;
(5) With the corresponding input power supply terminal or socket good contact and prevent
oxidation;
(6) With a multi meter measure the input voltage is within the fluctuation range;
(7) The power ground is well grounded.
