Connection of the TIG Torch
Connect the welding torch as shown in the picture to the (-) work piece socket, the water connections, the
remote control socket and the gas output. Observe the colours of the water connections.
Wire feed unit with control cable must be connected into the machine.
Connection of shielding gas cylinder
Put the Gas cylinder at the back of the bottle cart and secure it with the chains. Connect cylinder pressure
reducer and check that all connections are tightly sealed. Set the shielding gas flow rate at the pressure reducer
on cylinder (6- 18 l/min). The gas flow rate depends chiefly on the welding amperage.
Potentiometer for welding current control enable (only MC 1)
To be able to regulate the welding current with a potentiometer in TIG mode, it must be connected as shown in
the picture above or see circuit diagram at the 17-pole remote control socket.
Further must be called in MIG mode the control function Fx, and under Point ‚remote control EC 1’ the parameter
‚Curr - CAn’ must be adjusted.
Connection of work piece cable
Clamp the work piece cable into the +socket, choose an appropriate spot without paint or rust for good
conductivity.
Starting the welding process
Set the MC control box to the TIG mode, adjust the parameters for the welding job and start welding process by
pressing the torch trigger
Ensure excellent contact between all connections within the welding circuit,
i.e. work piece, torch connection and contact tip nozzle. Bad contact causes high transition
resistance which leads to overheating and poor quality of the weld.
