3.09 Welding Parameters
Parameter Description
Arc Force
This parameter provides an adjustable short circuit current in STICK welding
to improve electrode sticking and arc stability.
Hot Start
This parameter operates in STICK weld mode and is used to improve the
start characteristics for stick electrodes. e.g. low hydrogen electrodes. This
parameter also works in TIG mode allowing a softer or harder arc start. It sets
the peak start current on top of the (WELD) current.
Weld Current (Amperage) - when lit Encoder Control sets the STICK and TIG
WELD current.
Weld Voltage (Volt) – when lit Encoder Control sets the MIG voltage.
Local Control
Remote Control
Contactor Control
Contactor operates in MIG, TIG , and Stick modes.
When the local Control LED is illuminated the output is enabled, and when the
Remote Control is illuminated the output is enabled by a remote control.
Local Control
Remote Control
Remote Control
Selects either local or remote amperage or voltage control depending on the
selected process. Local Control allows the voltage or current to be adjusted
on the front panel, while Remote Control is used if you have a remote control
connected to the welder.
Inductance
This parameter, similar to the Arc Force in Stick mode. In MIG mode,
inductance 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 10
jobs into the 400MST memory.
