should be connected to the positive (+) weld output connection on the front of
the machine. The ground cable would then be connected to the negative (-) weld
output connection.
ii. Electrode Negative for Flux Core Welding - The Weld Power Cable should be
connected to the negative (-) weld output connection on the front of the machine.
The ground cable would then be connected to the positive (+) weld output
connection. Refer to the polarity setting label inside the wire compartment.
iii. Connect one end of the gas hose to the gas hose connection on the back of the
welder. Use a wrench to snug up the connection.

iv. Connect the other end of the gas hose to the gas hose connection on the
supplied regulator/flow gauge. Use a wrench to snug up the connection.
v. Before installing the regulator, it is good practice to make certain no debris is in
the gas bottle connection. Rotate the bottle so the gas connection is not pointing
toward you or any other person. Turn the valve on the gas bottle clockwise and
quickly close. This quick thrust of gas will clear any debris in the connection.
Connect the regulator to the gas bottle connection. Use a wrench to snug up the
connection.
vi. Open the Gas Bottle Valve on the cylinder of gas.
vii. Turn the Gas Flow Adjuster on the regulator so that the gas flow rate is set at
approximately 20 CFH. Make certain you are reading the correct scale on the
gauge.
