Additional Warnings
FOR YOUR SAFETY, BEFORE CONNECTING THE POWER SOURCE TO THE LINE
CLOSELY FOLLOW THESE INSTRUCTIONS:
• An adequate two-pole switch must be inserted before the main outlet. This switch must be
equipped with time-delay fuses.
• The ground connection must be made with a two-pole plug compatible with the above
mentioned socket.
• When working in a confined space, the welder must be kept outside the welding area and
the ground cable should be fixed to the workpiece. Never work in a damp or wet confined
space.
• Do not use damaged input or welding cables.
• The welding torch should never be pointed at the operator or other people.
• The welder must never be operated without its panels attached. This could cause serious
injury to the operator and could damage the equipment.
Assembly
Torch Connection
Connect the standard MIG torch to the threaded connector on the front of the welder and tighten firmly
by hand.
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.
