Weld Mode
Weld Parameter
STICK MIG
LIFT
TIG Description
WELD (V) Weld voltage MIG Mode.
INDUCTANCE Inductance control in MIG Mode.
HOT START Start current in amps is added to the WELD (A).
WELD (A) WELD (A) current for STICK or LIFT TIG.
ARC CONTROL Adjusts percentage increase in welding current and is
proportional to arc length (arc voltage).

3.04 Weld Parameter Descriptions
3.04.01 WELD (V)
This parameter sets the MIG weld arc voltage in MIG mode.
3.04.02 INDUCTANCE
This parameter sets the INDUCTANCE when MIG welding. It controls the dynamic properties of the arc
in dip transfer welding mode. When this parameter is set to 0%, i.e. minimum inductance, the arc has
a fast response with a resulting crisp arc noise and coarse spatter. When this parameter is set to
100%, i.e. maximum inductance, the arc has a slow response with a resulting soft arc and fine spatter.
NOTE 7
As the INDUCTANCE is increased, the WELD (V) may need to be adjusted to achieve the desired
weld characteristic.
3.04.03 HOT START
This parameter operates in STICK mode and improves the start characteristics for stick electrodes. e.g.
low hydrogen electrodes. It sets the peak start current on top of the WELD current.
e.g. HOT START current = 150 amps when Weld Current = 100 amps & HOT START = 50A
3.04.04 WELD (A)
This parameter sets the STICK & Lift TIG weld current.
