3. Positive Terminal:
Welding current flows from the Power Source
via heavy duty Dinse type terminal (25 mm)
It is essential, however, that the male plug
is inserted and turned securely to achieve a
sound electrical connection.
4. Negative Terminal:
Welding current flows from the Power Source
via heavy duty Dinse type terminal (25 mm)
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.

Torch/Gas Terminal:
Torch/Gas Terminal is an all-in-one design of
the Gas Outlet and the Negative Terminal. Gas
Outlet is a BSP-3/8 inch female gas fitting.
6. ON/OFF Switch:

age to the inverter when in the ON position.
This enables the Power Supply.
