INSTALLATION INSTRUCTION
The machine is equipped with power voltage compensation equipment. When power voltage moves
between
±
15% of rated voltage, it still can work normally.
When use long cable, in order to prevent voltage from going down, bigger section cable is suggested. If
cable is too long, it may affect the performance of the power system. So we suggest you to use configured
length.
1.
Make sure intake of the machine not blocked or covered, lest cooling system could not work.
2.
Make good connection of shielded gas source. Gas supply passage includes cylinder, argon
decompress flow meter and pipe. Connecting part of pipe should used hoop or other things to fasten,
lest argon leaks out and air gets in.
3.
Use inducting cable whose section is not less than 6 mm
²
to connect the housing to the ground. The
way is from the ground-connecting screw at the back to the earth device.
4.
Correctly connect the arc torch or holder according to the sketch. When use MMA welding: Make sure the
cable, holder and fastening plug have been connected with the ground. Put the fastening plug into the
fastening socket at the “-”polarity and fasten it clockwise. When use pulse arc welding: Put the gas-electricity
plug of the welding gun to the joint at the front panel, and fasten clockwise. Put the air switch on the gun to
the relevant joint at the front panel, and fasten the screw.
5.
Put the fastening plug of the cable to fastening socket of “+” polarity at the front panel, fasten it clockwise,
and the earth clamp at the other terminal clamps the work piece.
6.
According to input voltage grade, connect power cable with power supply box of relevant voltage
grade. Make sure so mistake and make sure the voltage difference among permission range. After
the above job, installment is finished and welding is available.
7.
VRD Function: Protection against electric shock
When the welder is at MMA state, the output voltage is in 24 safety voltage. When it is in the short
circuit, the welder can be tested by itself automatically. It can make the voltage up to 60V in order to
start the arc and make the welder to work normally. When stopping welding, please post 3s-5s to
keep the output voltage in 60V facilitate welding again to start the arc. When the welder doesn’t
work more than 5s, the output voltage will be descended to 24V to avoid that the operator is
uncareful to get an electric shock when using the welder or change the electric stick.
