Programming Parameter Adjustment
Device
Display Factory
Setting
Hot Start
This parameter operates in all weld modes and
is used to heat up the weld zone in TIG modes
or improve the start characteristics for stick
electrodes the peak start current on top of the
BASE (WELD) current.
e.g. HOT START current = 130 amps when
BASE (WELD) = 100 amps & HOT START = 30
amps
Range: 0 to 70Amps
(max 160A weld
current)
40 Amps
Base Current
This parameter sets the current in DC or AC
TIG mode, and the lowest current in DC or AC
Pulse TIG mode. This parameter also sets the
welding current in STICK mode.
Range: 10 to 160 Amps
120 Amps
Arc Force (STICK Mode only)
Arc Force is effective when in Stick Mode only.
Arc Force control provides and adjustable
amount of Arc Force (or "dig") control. This
feature can be particularly beneficial in
providing the operator the ability to compensate
for variability in joint fit-up in certain situations
with particular electrodes. In general increasing
the Arc Force control toward 100% (maximum
Arc Force) allows greater penetration control to
be achieved.
Range: 0 to 100%
30%

6.03 Arc Welding Electrodes
Metal arc welding electrodes consist of a core wire surrounded by a flux coating. The flux coating is applied
to the core wire by an extrusion process.
The coating on arc welding electrodes serves a number of purposes:
A. To provide a gaseous shield for the weld metal, and preserve it from contamination by the atmosphere
whilst in a molten state.
B. To give a steady arc by having ‘arc stabilisers’ present, which provide a bridge for current to flow across.
C. To remove oxygen from the weld metal with ‘deoxidisers’.
D. To provide a cleansing action on the work piece and a protective slag cover over the weld metal to prevent
the formation of oxides while the metal is solidifying. The slag also helps to produce a bead of the desired
contour.
E. To introduce alloys into the weld deposits in special type electrodes.
