gas CYlinder and regulator ConneCtion

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.
The bottle (not supplied) should be located at the rear
of the welder, securely held in position by the chain
provided.
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-
clock wise to ensure the valve is fully closed.
• Screw the gas regulator fully down on the gas
bottle valve, and fully tighten.
• Connect the gas hose to the regulator secu-
ring with clip/nut provided.
• Open the cylinder valve, then set the gas flow
to approx. 8l/min. on the regulator.
• Operate the torch trigger to ensure that the
gas is flowing through the torch.
