Connection of welding and return cable
The power source has two outputs, a positive terminal (+) and a negative terminal (-), for
connecting welding and return cables. The output to which the welding cable is connected
depends on the welding method or type of electrode used.
Connect the return cable to the other output on the power source. Secure the return cable's
contact clamp to the work piece and ensure that there is good contact be tween the work
piece and the output for the return cable on the power source.
For MMA welding, the welding cable can be connected to the positive terminal (+) or
negative terminal (-) depending on the type of electrode used. The connecting polar ity is
stated on the electrode packaging.
