Parameter Description
Operation
PANEL/REMOTE
Selects in operation Panel board or Remote.
INDUCTANCE
This parameter, similar to the ARC CONTROL in STICK mode, allows for the
adjustment of the dynamic property of the arc. As the inductance is increased the
output voltage may need to be adjusted to achieve the desired weld characteristics.
The SAVE/LOAD buttons are used to save and retrieve a total number of 5 programs
into the 300 MST memory.

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.
