should be used
when using the MIG (GMAW - GAS Metal Arc Welding). The flow regulator and supply hose is
included with your welder. The compressed gas can be obtained from your local welding supplier.
1.
Fix the compressed gas cylinder with a chain, or other method to the wall or other securing device,
to prevent the cylinder of falling.

After securing, remove cylinder cap if there is one on your cylinder.
3.
Install flow regulator (CGA-580) to the supply valve on the cylinder and tighten with wrench.
4.
Install one end of the gas supply hose into the outlet of the flow regulator and tighten. Connect the
other end of the hose to the gas inlet located at the rear of the MIG140 welding machine (The
connector nipple 5/8-18 adapts to CGA-032). Ensure that the hose has no twisting or knotting.
5.
Slowly turn on the gas cylinder valve.
6.
Depress gun trigger switch and adjust the flow regulator to 25-30 cubic ft per hour (CFH), (12-14
l/min).
7.
Shut off the valve of the gas cylinder. Depress gun trigger to release the gas in system. Power off
MIG140, when welding process is finished.
