tighten it clockwise.
Connect one end of the positive output cable to the positive quick coupling, and
o
the other end to the electrode holder.
Connect the positive quick coupling to the positive pole of the output end and
o
tighten it clockwise.
(2) Argon arc welding connection method
Connect one end of the positive output cable to the positive quick coupling, and
o
the other end to the job.
Connect the positive quick coupling to the positive pole of the output end and
o
tighten it clockwise.
Connect the two-core control plug in the argon arc welding torch cable to the
o
control connector (welding torch switch) and tighten it, and connect the cable
connector in the argon arc welding torch cable to the negative quick coupling.
Connect the negative quick coupling to the negative pole of the output end and
o
tighten it clockwise.
Connect the air pipe of the argon cylinder to the input of the gas inlet. Please
o
refer to the structure diagram of back panel for the location of the input gas
connection.
Connect the air pipe of argon arc welding torch to air outlet nozzle of the air
o
outlet. Please refer to the front panel structure diagram for the position of the air
outlet nozzle.

CAUTIONS FOR INSTALLATION

 Provide a Switch Box for every Welding Power Source, and use designated
fuse
 Tolerance of Power Voltage Variation is  10% of rated input voltage.
a) Installation place
 Install in the place where less moisture and dust exist. Avoid direct sunlight and
rain, and maintain ambient temperature within –10
possible.
 Keep the welding power source at least 20 cm. away from the wall (if any).
 In case of installation of more two units side by side, a distance of more than 20
cm is recommended between the two power sources.
 Use a shield to protect the welding arc in case of excessive air draft.
