► all the operating instructions for the system components, especially the safety rules
WARNING!
An electric shock can be fatal.
If the machine is plugged into the mains electricity supply during installation, there is a high
risk of very serious injury and damage. Do not carry out any work on the device unless

IMPORTANT!
Check the rod electrode packaging to determine whether the rod electrodes are for
(+) or (-) welding.
Plug the grounding (earthing) cable into the (-) or (+) current socket (depending upon
which type of electrode is to be used) and latch it by turning it clockwise
With the other end of the earthing (grounding) cable, establish a connection to the
workpiece
Plug the bayonet current plug of the electrode holder cable into the free current socket
with the opposite polarity, according to the type of electrode, and twist it clockwise to
latch it in place
