Interface Switch
To enable interfacing move the
switch to the ‘II’ position,
unscrew the interface socket cap and plug in
the amp clamp. Connect the amp clamp in the correct orientation to the welding torch. Please note there will be a
small delay from starting the welding process to the extraction unit being up to speed. When the welding has been

standby mode.
