1)
Connect to the appropriate voltage level according to the input voltage of the welder. Do not mismatch the
voltage level.
2)
The input power cable should be in good contact with the corresponding power terminal or socket to
prevent poor contact.
3)
Use a multimeter to measure if the input voltage is within the fluctuation range.
4)
Insert the cable plug with welding tongs into the positive socket under the front panel of the welder and
tighten it clockwise.
5)
Insert the cable plug with ground clamp into the negative socket under the front panel of the welder and
tighten it clockwise.
6)
Ground the power supply properly.
The operator can also choose the DC connection method according to the condition of the parent metal and the
welding rods. In general, DC reverse connection method is recommended for basic welding rod (that is, the
welding rod is connected to the positive electrode); no special provision is made for acid welding rods.
13.2 Electric
connection
Warning! Electric shock may result in personal death; high voltage direct current still exist on
equipment even after power-off, please do not contact the current-carrying part on equipment.
Warning! The electric connection of equipment must be performed by qualified electrician with
qualification certificate.
Warning!
Do not connect the power cord (blue /brown/black)to ground terminal.
Do not connect the ground wire(yellow/green ) to power cord.
Warning!
Improper power supply voltage may damage equipment.
1)
This welding machine is equipped with power source voltage compensation system, so it still can work on
normally when the power source voltage varies within ±15% range of rated voltage.
2)
Connect the power cord to the corresponding voltage class of distribution box according to input voltage
class of welding machine, don’t connect the voltage by mistake. Meanwhile, make sure that tolerance of
supply voltage is within the allowable range. Voltage of the product is 400V~, 50Hz three-phase.
