2.Install proper drive roll for the wire size selected. See “Changing Drive Roll” in Maintenance section for details.

3.Install the proper gun liner and tip for the wire size selected. See “Component Replacement” in Maintenance section for details.

4.Remove gas nozzle (if installed) and install gasless nozzle.

5.Load wire into machine and thread into gun and cable per “Welding Wire Loading” section.
