The welding machine has installed protection circuit of over voltage and current and heat. When voltage and output
current and temperature of machine are exceeding the rate Standard, welding machine will stop working automotically.
Because that will damage to welding machine, user must pay attention as following:
4)
The working area is adequately ventilated.
The welding machine is powerful machine, when it is being operated, it generated by high currents and natural wind
will not satisfy machine cool demands. So there is a fan in inter-machine to cool down machine. Make sure the intake is
not in block or covered, it is 0.3meter down from welding machine to objects of environment. User should make the
working area is adequately ventilated. It is important for the performance and the longevity of the machine.
5)
Avoid to overload.
The operator should remember to watch the max duty current (Response to the selected duty cycle). Keep welding
current is not exceed max duty cycle current. Overload current will damage and burnu p machine.
6)
No over voltage.
Power voltage can be found in diagram of main technical data. Automatic compensation circuit of voltage will assure
that welding current keep in allowable arrangement. If power voltage is exceeding allowance arrangement limited, it is
damaged to components of machine. The operator should understand the situation and take preventive measures.
4) There is a grounding screw behind welding machine, there is grounding marker on it. Mantle must be grounded
reliable with cable which section is over 6 square milimeter lorder to prevent from static electricity and leaking.
5) If welding time is exceeded duty cycle limited, welding machine will stop working for protection. Because machine
is overheated, temperature control switch is on ‘ON’ position and the indicator light is red. In this situation, you don’t
have to pull the plug, in order to let the lan cool the machine. When the indicator light is off and the temperature goes
down to the Standard range, it can weld again.
ABOUT MACHINE
The welding machine is a rectifier adopting the most advanced inverter technology. The development of inverter gas-
shielded welding equipment profits from the development of the inverter power supply theory and component MOSFET
to transfer 50/60HZ frequency up to 100KHZ, then reduce the voltage and commutate and output high-power voltage
via PWM technology. Because of the great reduce of the main transformer’s weight and volume; the efficiency
increases by 30%. The appearance of inverter welding equipment is considered to be a revolution for welding industry.
The welding power source can offer stronger, more concentrated and more stable arc. When stick and work piece get
short, its response will be quicker. It means that it is easier to design into welding machine with different dynamic
characteristics and it even can be adjusted for specially to make arc softer or harder.
The MMA welding machine has the following characteristics: effective, power saving, compact, stable arc, good
welding pool, high no-load voltage, good capacity of force compensation and multi-use. It can weld stainless steel, alloy
steel, carbon steel, copper and other color metal. It can apply to electrode of different specifications and materials,
including acidity, alkalescence and fibre. It can apply to in high altitude, the open afr 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.
Thanks for puchasing the product and hope for your precious advice. We will dedicate to produce the best products and
offer the best service.
CAUTION:
The machine is mainly used in industry. It will produce radio wave, so the worker should make fully preparation for
protection.
INSTALLMENT
The induction power is equipment with power voltage compensation equipment. When power voltage moves between
±15% of rated voltage, it stil can work normally.
