3. Positive Terminal
Welding current fl ows from the Power Source via heavy
duty Dinse type terminal. It is essential, however, that
the male plug is inserted and turned securely to achieve
a sound electrical connection.
4. Negative Terminal
Welding current fl ows from the Power Source via heavy
duty Dinse type terminal. It is essential, however, that
the male plug is inserted and turned securely to achieve
a sound electrical connection.
CAUTION
Loose welding terminal connections can cause
overheating and result in the male plug being
fused in the bayonet terminal.
5. ON/OFF Switch
This switch connects the Primary supply voltage to the
inverter when in the ON position. This enables the Power
Supply.
!
WARNING
When the welder is connected to the Primary
supply voltage, the internal electrical components
maybe at 240V potential with respect to earth.
6. Input Cable
The input cable connects the Primary supply voltage to
the equipment.

Parameter Description
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.
A Weld Current (Amperage)- sets the STICK and TIG WELD current.
ARC CONTROL - This parameter provides a suitable short circuit current in STICK welding
to improve electrode sticking and arc stability.
LIFT TIG mode of operation. A remote control device is required for use during LIFT TIG
operation. See section 3.01, section 2 “Remote Control Socket”, for complete details of
the remote device.
STICK Mode of operation.
