A. Remove all packaging materials. Do not block the air vents at the front or rear of the Power Source.
B. Connect the Electrode Holder to the positive welding terminal (+) (or negative welding terminal (-)). If in doubt,
consult the electrode manufacturer. Welding current flows from the Power Source via dinse type connectors. It
is essential, however, that the male plug is inserted and turned securely to achieve a sound electrical connection.
C. Connect the work lead to the negative welding terminal (-) (or positive welding terminal (+)). If in doubt, consult
the electrode manufacturer. Welding current flows from the Power Source via dinse type connectors. It is
essential, however, that the male plug is inserted and turned securely to achieve a sound electrical connection.
!
WARNING
The polarity of the electrode depends on the type of electrode and the welding process. Please follow
the manufacturer's instructions on the electrode packaging for this purpose.
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug being fused in
the terminal.
!
WARNING
Before connecting the work clamp to the workpiece make sure the mains power supply is switched
off.
D. Select STICK mode by pressing Process Selection Button until the STICK/Gouging and 6010 Process LEDs are
lit (Please refer to Page 3-8 for detailed info).

E. Arc ignition. Briefly touch the workpiece at the point to be welded using the electrode and lift the electrode a
little. The arc burns between the workpiece and the electrode.
