come out of the threated end.
Turn the input power OFF.
Depending on welding process, connect the proper gun to the euro socket, the rated parameters of the gun and of
the welding machine should be matched.
Remote the nozzle from the gun and contact tip or protection cap and contact tip. Next, straighten the gun out flat.
Insert the wire through the guide tube, over the roller and through the guide tube of Euro Socket into liner of gun.
The wire can be pushed into the liner manually for a few centimeters, and should feed easily and without any
force.
Warning: If force is required it is likely that the wire has missed the liner of gun.
Turn the input power ON.

[35] Adjusting screw M10.
[36] Pressing spring.
Turning the screw M10 clockwise increases the spring tension and you can increase the brake torque.
Turning the screw M10 anticlockwise decreases the spring tension and you can decrease the brake torque.
After finishing of adjustment, you should screw in the fastening cap again.
Gas Connection
Connect the gas hose to the Gas Connector located on the rear panel of the machine.
Put the gas cylinder on the machine shelf and secure it with the chain.
A gas cylinder must be installed with a proper flow regulator.
Once a gas cylinder with a flow regulator has been securely installed, connect the gas hose to the regulator using
the hose clamp.
