About this machine
This product is a rectifier adopting the most advanced inverter technology available and it can be described as an Inverter Synergic NO GAS MIG/MAG+ MMA+ LIFT TIG 3 in 1 welding machine.
The development of inverter gas shielded welding equipment profits from the development of the inverter power supply theory and components. Inverter gas- shielded welding utilizes the high-power component IGBT to transfer 50/60HZ frequency up to 100 kHz, then reduces the voltage and commutate output high- power voltage via PWM technology. Because of the reduction 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 in the welding industry.
CO2 shielded welding equipment adopts the most advanced inverter technology. The welding machine is equipped with an electronic reactor circuit that can accurately control the process of the electric short transition and blending transition and result in excellent welding characteristics. Compared with synergic welding machines and other machines, it has the following advantages: stable wire speed, compact, power saving, and no electromagnetic noise. Continuous and stable operation with a small current, especially suitable for welding sheets of low-carbon steel, alloyed steel, and stainless steel. Automatic voltage pulsation compensation capability, small sparkle, good arcing, uniform welding pool, high duty cycle, and so on.

Installation

The welding equipment is equipped with a power voltage compensation set. When power voltage changes between ±15% of rated voltage, it still works normally. When using a long cable, in order to minimize the reduction of voltage, a cable of the big section is suggested. If the cable is too long, it will affect the performance of arcing and other system functions, so the stated length is suggested.

Make sure the intake of the machine is not covered or blocked to prevent the malfunction of the cooling system.
Use an earth cable that the section no less than 6 mm2 to connect the housing and earth, the method is from the connection in the back of the machine to the earth set, or make sure the earth end of the power switch reaches the earth. Both ways can be used for better security.

Installation:

Connect the gas flask with the CO2 decompression flow meter and the CO2 mouth behind the machine via gas cable.
Insert the swift plug of earth cable into the swift socket in the front panel.
Set the wire wheel with wire on the wheel axis, the wheel hole should be matched with the wheel fixer.
Choose the wire slot according to the wire size.
Loosen the screw of the wire-pressing wheel, put the wire into the slot via a wire-lead tube, and tune the wire-pressing wheel to fix the wire from gliding, but pressure should be suitable in case the wire distorts and affects were sending.
The wire roll should turn clockwise rotation to let out the wire, to prevent the wire from gliding, the wire is usually set to the fixed hole on the wheel side. To prevent the
bent wire from getting stuck, please cut off this part of the wire.
The MIG torch has been settled inside of the machine just need to put the wire into the torch by hand.

Operation

Put the air switch to the “ON” position, open the valve of the CO2 cylinder and adjust the flow.
Adjust the wire diameter of the wire machine to a rated number according to wire diameter.
Choose torch loophole span based on wire diameter.
Tune the voltage knob, speed knob, and inductance knob to the right position based on the thickness of the workpiece and mechanics.
Press the torch switch to let out the wire to the torch head and begin to work.

Notes & Preventive Measures

A. Environment

The machine can perform in environments where conditions are dry with a max humidity level of 90%.
The ambient temperature is between 10 degrees to 40 degrees centigrade.
Avoid welding in bright sunshine or wet conditions.
Do not use the machine in an environment where there is conductive dust or corrosive gas in the atmosphere.
Avoid gas welding in an environment with strong air flows.

B. Health and Safety
The welding machine has installed a protection circuit for over-voltage and current and heat. When the voltage and output current and temperature of the machine are exceeding the rate standard, the welding machine will stop working automatically. Because that will damage the welding machine, the user must pay attention as follows.

The working area is adequately ventilated!
A welding machine is a powerful machine, when it is being operated, it is generated by high currents, and natural wind will not satisfy machine cool demands.
So there is a fan in the inter-machine to cool down the machine. Make sure the intake is not in a block or covered, it is 0.3 meters from the welding machine to objects of the environment. The user should make sure the working area is adequately ventilated. It is important for the performance and longevity of the machine.
Do not 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.
Over-load current will damage and burn up the machine.
No overvoltage!
Power voltage can be found in the diagram of the main technical data. An automatic compensation circuit of voltage will assure that the welding current keeps in the allowable arrangement. If power voltage is exceeding the allowance arrangement limit, it damaged the components of the machine. The operator should understand the
situation and take preventive measures.
There is a grounding screw behind the welding machine, and there is a grounding marker on it Mantle must be grounded reliably with a cable whose section is over 6 square millimeters in order to prevent static electricity and leaking.
If welding time is exceeded duty cycle limited, the welding machine will stop working for protection. Because the machine is overheated, the 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 fan cool the machine. When the indicator light is OFF, and the temperature goes down to the standard range, it can weld again.

Welding
Fittings, welding materials, environmental factors, and supply powers maybe have something to do with welding. Users must try to improve the welding environment.

A. Arcing-striking is difficult and easy to pause:

Make sure the earth cable clincher connects the workpiece well.
Check whether each connecting point is connected or not.

B. Output current can not reach rated volume:
That supplied voltage is different from the rated will lead to unconformity of the output current and the adjusted current. When supplied voltage lower than
the rated, the max output current will be lower than the rated.

C. Current is not stabilizing when the machine is been operating:

Electric wire net voltage has been changed
There is harmful interference from electric wire nets or other equipment.

Maintenance

Remove dust by dry and clean compressed air regularly, if the welding machine is operating in an environment that is polluted with smoke and polluted air, the machine needs to remove dust every day.
The pressure of compressed air must be inside a reasonable arrangement in order to prevent damage to small components of the inter-machine.
Check inter circuit of the welding machine regularly and make sure the cable circuit is connected correctly and connectors are connected tightly (especially insert connector and components). If scale and loose are found, please give a good polish to them, then connect them again tightly.
Avoid water and steam entering into inter-machine, if they enter into machine. Please dry the inter-machine then check the insulation of the machine.
If the welding machine will not be operated for a long time, it must be put into a package and stored in a dry environment.
When the wire machine operates every 300 hours, the electric carbon brush and armature rectifier should be polished, the reducer should be cleaned, and the lubricator should be added to the turbo and bearing. Caution: It is recommended that only a qualified technician tests and attempts repair on this high volt-age machine. Incorrect diagnoses or repairs may lead to serious injury or death! Before Maintenance and checking, power must always be turned off, and before any opening of the housing, make sure that the power plug is pulled off.

Troubleshooting

If the user wants to operate the machine as follows, the operator must be personnel in a specific field of electricity and safety and hold the relevant certificate that proves their ability and knowledge. Before maintenance, contact with our for authorization is suggested.
