1、CHARACTERISTICS
HC-D series welding machine have CO2 and MMA function (if make use
appointed welding torch, also can bring about simple TIG function). HC-D
series machine can be used widely in various fields. Its characteristics are as
following:
1.1 With high quality for welding
Adopted high-quality and advanced control circuit, with good dynamic
response, and it can easier achieve nice-looking weld slot.
1.2 With obvious electricity saving
Adopted inverter technology and voltage equalization, can deeply reduces
the input capacity, meanwhile saving electricity.
1.3 With presetting function
The welding current and voltage can be preset in advance, and it is easy to
be read via digital display meter. It is more useful for beginner.
1.4 With lighter weight and smaller dimension
Compared with rectifier/thyristor model welding machine, HC-D series
machine 1/3 of rectifier machine, and its weight is 1/4 of rectifier machine.
So it is more convenient for outside working.
1.5 With less splash
With wave-form control technique, the splash while welding is deeply
reduced. and suitable for welding from all position.
1.6 With high ratio of arc ignition
The arc ignition ratio can be reached 100% via special ignition circuit.
1.7 For MMA usage
The arc-ignition current can be adjusted while welding, and the welding
rod is not easy to be agglutinated with workpiece. With arc force circuit
design, the arc characteristics can be adjusted according to welding
technology. The welding is stable and with less splash.
1.8 With stable welding process
Adopt high-speed feedback circuit,welding system can be anti-interference
and resistance network fluctuation,thus realize the stable welding process

7、DAILY MAINTENANCE AND TROUBLE SHOOTING
Warning:
Only after switching off the power supply and ensuring safety, the welding
machine can be opened up for check. Otherwise it may cause electric shock or
burn and other safety accidents
7.1 Attention ：
a. Connect cable to port well. Any damage can influence the stability when
welding.
b. Forbid the bare cable and port to be touched by other metal, avoid short
circuit.
c. Avoid breaking the cable.
d. Avoid knocking or heavy weight.
e. Keep good ventilation.
f. Daily maintenance is not enough. In order to keep excellent performance,
periodic maintenance and checking and cleaning the inside components
is necessary.
g. In normal condition, there will be quantity of spark mote and oil dust.
Check and clean in every three months.
h. Check cables including the adjusting button and spares in panel regularly.
i. Change contact tube and wire feeder wheel and clear wire feeder pipe
regularly.
