• Create the connection between the G1/4 shielding gas connecting nipple, welding machine output and
the G1/4 shielding gas connecting nipple, gas metering unit input to the G1/4 gas connection line.
• Create the connection between the G1/4 plasma gas connecting nipple, welding machine output and
the G1/4 plasma gas connecting nipple, gas metering unit input to the G1/4 gas connection line.
• Screw adapter (G1/4 > G1/8) onto G1/4 shielding gas connecting nipple, gas metering unit output.
• Screw adapter (G1/8 > cap) onto adapter (G1/4 > G1/8).
• Screw adapter (G1/4 > G1/8) onto G1/4 plasma gas connecting nipple, gas metering unit output.
• Screw adapter (G1/8 > plug-in nipple) onto adapter (G1/4 > G1/8).
• Insert the plug on the welding current lead into the "-" welding current connection socket and lock.
• Insert the plug of the pilot power line into the "+" pilot current connection socket.
• Insert the torch control lead plug into the “5-pole connection socket, welding torch control lead” and
lock.
• Insert connecting nipple on the torch shielding gas line into adapter (G1/8 > cap).
• Insert connection socket on the torch plasma gas line onto adapter (G1/8 > plug).
