to electrode of different specifications and materials, including acidity, alkalescence, and fibre. It
can apply in high altitude, the open air and inside and outside decoration. Compared with the same
products of home and abroad, it is compact in volume, light in weight, easy to install and operate.
3. Installation instruction
DC welding machine has two connecting ways: positive connection and negative connection.
Positive connection: holder connects with "-" terminal, while work piece with the "+" terminal.
Negative connection: work piece with the"-" terminal, holder with the "+" terminal. Choose suitable
way according to the working situation. If unsuitable choice is made, it will cause unstable arc, more
spatters and conglutination. If such problems occur, please change the polarity of the fastening
plug.
3.6. According to input voltage grade, connect power cable with power supply box of relevant
voltage grade. Make sure no mistake is made and make sure the voltage difference is among
permission range. After the above job, installation is finished and welding is available.
!!! If distance of work piece and machine is too far (10-50m), and the cables (torch cable and earth
cable) are too long, please choose cable of bigger section to minimize the reduction of the voltage.
4. Operation
4.1. Turn on the power switch, the screen will show set current value and ventilator is beginning
to run.
4.2. Adjust knobs of welding current and arc-striking push, make welding function complies with
demands.
4.3. Generally, welding current is adequate to welding electrode according with as following:
Specification
Current
4.4. Knob of arc-striking drive is use to adjust welding function, specially in low current arrange,
that is cooperated with knob of welding current adjustment, they may adjust current of arc striking
and be out of control of knob of welding current adjustment .So machine can grain powerful energy
and push current can achieve effect that may .
The
compensation equipment. When the power voltage
fluctuation is between±15% of rated voltage, it still can
work normally.
to prevent voltage from going down, bigger section
cable is suggested. If the cable is too long, it may affect
the performance of the power system. So cables of
configured length are suggested.
or covered to avoid malfunction of cooling system.
6mm2 to the housing, the way is connecting screw in the
back of the power source to ground device .
according to the sketch. Make sure the cable, holder and
fastening plug have been connected with the ground.
Put the fastening plug into the fastening socket at the "-"
terminal and fasten it clockwise.
socket of "+" terminal at the front panel, fasten it
clockwise, and the earth clamp at the other terminal
clamps the work piece.
