Operators Manual
Trusted by the best
Austarc 16TC, Classification E4916-A
A low hydrogen electrode with good
arc stability and out-of-position welding
characteristics. This electrode is ideal for
medium carbon steels, or steels of unknown
analysis.
Austarc 11, Classification E4311-A
A high cellulose electrode for all positional
welding, AC or DC. Particularly suited for
vertical and incline pipe welding where
complete root penetration is required.
Unicord 312, Classification ES312-16
A high tensile (50tsi), chromium nickel
electrode specially formulated for joining all
alloy steels and irons, and for tool and die
maintenance.
GTAW (TIG Welding)
Gas Tungsten Arc Welding (GTAW) is a
welding process where the arc is struck
between a non-consumable tungsten
electrode and the work piece. A ceramic
nozzle surrounds the tungsten electrode and
directs a flow of inert gas, usually Argon, over
the electrode and the weld zone. If filler metal
is required, it is hand fed into the welding arc.
The DC current output of the Weldmatic 200i
is suitable for welding most ferrous and
non-ferrous metals, but is not suitable for
welding Aluminium for which an AC machine
is required.

IMPORTANT NOTICE: Warranty may
be voided if equipment is powered
from an unsuitable engine driven
generator.
Generators used to power
this equipment must have the
recommended minimum capacity and
incorporate output voltage regulation.
Due to variation between generators by
different manufacturers, it is impossible
for WIA to validate operation from all
generators. Therefore, correct operation
of welding equipment on the generator
should be confirmed by the manufacturer,
before purchasing the generator.
