Connecting output terminals

The Ruffian ES 150G EDW is a DC (direct current) power source for STICK welding has Positive
(+) and Negative (-) terminals for welding and return cables, in most cases the connection as
follows:
Connect the return cable to the negative terminal on the power source. Secure the return cable's
contact clamp to the workpiece, and make sure that there is a good contact between the
workpiece and the output for the return cable on the power source.
NOTE!
The polarity of the welding cables depends on the type of electrode and their
specifications. Before use, refer electrode's data sheet.
