INSTALLATION
Input wiring
Ensure that the voltage, number of phases, frequency and capacity of the input
o
power are consistent with the calibration values on the nameplate of the welding
machine.
Wiring shall be performed by professional electrician.
o
The input cable and air inlet are located on the back panel of the welding machine.
o
Please refer to the structure diagram of welding machine for detailed location.
Connect the input cable to the power to ensure the reliable connection.
o
The casing must be grounded, and the grounding bolt is located at the lower right
o
corner of the back panel of the welding machine and marked with a grounding
mark.
Confirm the air inlet is connected smoothly with the argon cylinder during the weld
o
of argon arc welding.
The recommended specifications of ground wire, fuse protector or breaker are as
