Torch Lead and Spool Gun Assembly

• Plug the torch hose into the socket on the front of the welder, be careful not to damage the
contacts. Secure by hand screwing in the threaded connection (Fig. 3).
• To connect Spool Gun it is necessary to install also the terminals to the 7 pole connector on
the front of the welder.

Gas Cylinder and Regulator Connection

The gas cylinder (not supplied) should be located at the rear of the welder, in a well-ventilated area
and securely fixed to the work bench or to the wall to ensure that it will not fall.
For safety and economy, ensure that the regulator is fully closed (turned counter-clockwise)
when not welding and when fitting or removing the gas cylinder.
• Turn the regulator adjustment knob counter-clockwise to ensure the valve is fully closed.
• Screw the gas regulator down on the gas bottle valve and tighten.
• Connect the gas hose to the regulator, securing with the clip/nut provided.
• Open the cylinder valve, then set the gas flow to approximately 20 - 35 CFH (cubic ft. per
hour) on the regulator.
• Operate the torch trigger to ensure that the gas is flowing through the torch.
WARNING: Cylinders are highly pressurized. Handle with care. Serious accidents can result
from improper handling or misuse of compresses gas cylinders. Do not drop the cylinder, knock
it over, expose it to excessive heat, flames or sparks. Do not strike it against other cylinders.
