4.02 Setup for Welding
NOTE
Conventional operating procedures apply when using the Welding Power Source, i.e. connect work
lead directly to work piece and electrode holder and lead is connected to the 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 welding 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.
4.03 Welding Current Control Explanation (US Version)
15 Amp Outlet
The mains power 15 Amp circuit breaker or fuse should not trip at this Weld Current value when STICK welding.
The environmental conditions that may cause the mains power 15 Amp circuit breaker or fuse to trip are:
a) High ambient temperature
b) Worn parts in circuit breaker
c) Using an extension cable
d) Low line mains power voltage
