Parameter Description
ARC CONTROL
This parameter provides a suitable 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. It sets the peak
start current on top of the
(WELD) current.
DC (A) Weld Current (Amperage)- when lit parameter knob sets the STICK and TIG WELD
current.
DC (V) Weld Voltage (Volt) – when lit parameter knob sets the MIG voltage.
Contactor ON/OFF
Contactor operation in Stick Mode.
