ARC MASTER 175 SE INSTALLATION
INSTALLATION 3-4 Manual 0-5054
3.05 Setup for Welding
NOTE
Conventional operating procedures apply when us-
ing the Welding Power Source, i.e. connect work
lead directly to work piece and electrode lead is used
to hold electrode. Wide safety margins provided by
the design ensure that the Welding Power Source
will withstand short-term overload without adverse
effects. The welding current range values should be
used as a guide only. Current delivered to the arc is
dependent on the welding arc voltage, and as weld-
ing arc voltage varies between different classes of
electrodes, welding current at any one setting would
vary according to the type of electrode in use. The
operator should use the welding current range values
as a guide then fine tune the welding current to suit
the application.
!
WARNING
Before connecting the work clamp to the work and
inserting the electrode in the electrode holder make
sure the Primary power supply is switched off.
CAUTION
Remove any packaging material prior to use. Do not
block the air vents at the front or rear of the Welding
Power Source.
