2. Installation
Be sure to use this welding machine with the specified cutting gun, earth clamp
together; otherwise, it will affect the welding performance and may damage the
machine.
• Connect the compressor’s pressurized pipe to the air inlet of the pressure regulator.
• Connect the copper nut on the cutting gun with the output terminal on the front of
this machine, and tighten this nut clockwise (to prevent gas leakage); connect the
rapid socket on the earth clamp with the positive output terminal on the front panel
of the cutter and tighten the socket.
• Connect the switch plug on the cutting gun with the switch connector of the cut-
ting gun on the panel. Screw the electrode into the cutting torch to the end, slightly
tighten them with force and then properly install the nozzle and protection cover in
a proper order.
Important to set the correct air pressure before cutting. At low pressures the arc con-
fident but the molten material of the cutting gap is therefore more difficult to leave
the cut surface will not be smooth. At high air pressure in the ignition more difficult,
but at the cutting surface is smoother.
Use the machine parameter table given pressure setting!
