1. Earth leakage protection device should be installed when you use the machine.
2. Within an indoor environment, the machine may produce radio waves, so the user should make full of preventive measures.
3. Please make sure the power supply is off before any connecting operation.
4. If the distance between the workpiece and machine is too far (50m), and welding cables are too long, please select the cable with a bigger section to reduce the voltage dropping.

SECURITY CAUTION

Please make good protection as there will be the possibility of harm during the arc welding process. For more details please refer to the Operator Safety Guide, which complies with the preventive requirements of the manufacturer.

INSTALLMENT
The welding machine is equipped with a power voltage compensation device. When power voltage fluctuates within ±10% of rated voltage, it can still work normally. In order to reduce the voltage drop when using long cables, cable of the bigger section is suggested. If the cable is too long, it may affect the performance of the power system as well as other properties, so we suggest you use the recommended length.

1. Be sure the vents are not blocked, lest the cooling system will not work.
2. Use inducting cable with the section not less than 6 mm² to connect the housing to the ground. The way is from the ground-connecting screw at the rear to the earth device.
3. Connect the power cable to the power supply box which is equipped with an earth leakage protection device. Make sure the input power is of the proper voltage and meanwhile please ensure the voltage fluctuation is within the applicable range.
4. In actual use, maybe the power cable and welding cable length are not enough, please refer to the below form to choose a suitable cable.

Warnings:

1. Please don’t connect or disconnect the cables during working, it will terribly damage the machine.
2. When the machine is powered by the generator, please don’t connect the powerful sensitive load to the generator(such as the power motor, air compressor, and so on), otherwise, the big power machine will damage the cutting machine.

INSTALLMENT & OPERATION

MMA

1. Open the cable connecting box at the rear of the machine and connect the power cable to the terminal screw then fasten it. After that please unscrew the screw of the cable fixing groove, remove the groove cover, fix the cable into the groove then install the cover and fasten the screw.

2. Put the cable connector of the electrode holder to the negative terminal “-“ of the front panel, and fasten it clockwise.

3. Please connect the earth clamp to the positive terminal “+”, and fasten it clockwise.

4. Please pay attention to the connecting polarity and there are two connecting methods for DC welding machines: positive connection and negative connection.
   4.1 Positive connection: holder connects with “-“polarity, work-piece with the “+” polarity.
   4.2 Negative connection: work-piece to the “-“polarity, electrode holder to the “+” polarity.
   4.3 Choose a suitable method according to the welding requirement. If the unsuitable method is selected, it will cause an unstable arc, more spatters, and sticking. If so, please change the polarity of the welding cables. Normally choose a positive connection.

5. Switch to “MMA”.

6. Switch on the power switch, meanwhile, the digital display will be on, then the cooling fan will start working immediately.

7. Please select the appropriate welding current and rod according to the thickness of the workpiece.

(Taking notice of distinction for the positive connection terminal between AC and DC welding)

   ---|---
   Soft Square wave| Easier to control the puddle
   Sine wave| Soft sounding arc
   Triangular wave| Reducing heat input on the thinner materials also provides better cleaning in the anodic oxidation application.

ATTENTION

1. Environment
   1.1 The machine can perform in an environment with dry air with a dampness proportion of max 90%.
   1.2 Ambient temperature should be between -10ºC to 40ºC.
   1.3 Avoid welding in sunshine or drippings.
   1.4 Please do not use the machine in the air which is polluted with conductive dust or corrosive gas.

2. Safety points
   The welding machine has adopted a protection circuit to avoid broken under over voltage, over current, and overheating. When the voltage, output current, and temperature of the machine exceed the standard level, the unit will stop working automatically. In order to avoid damage to the unit, the operator must pay attention to the following:

2.1 Please make sure the working area is adequately ventilated!
The machine adopts air cooling, so be sure the intake is not in a block or covered. It should be more than 0.3 meters from the welding machine to the surroundings. And good ventilation is important for better performance and the longevity of the unit.
2.2 No overload!
Please avoid working overload as it will shorten the machine’s life. Normally it’s overloaded if the current display shows abnormal code during welding, namely, its overrated duty cycle. So please stop welding immediately and resume working after the display is on normally. (Rated duty cycle 60% means: take 10 mins as a circle, the machine works for 6mins and stops for 4mins under the rated output current).
2.3 No overvoltage
An automatic compensation circuit of voltage will assure that the welding current is kept in the allowable arrangement. If the power voltage exceeds the limitation, it will damage the welder. In that case, please take relevant preventive measures.
2.4 Assure the ground screw is well connected
There is a ground screw with the symbol at the rear panel of the unit. Choose a section of inducting cable over 6mm 2 and reliably grounding to prevent static electricity and leaking.

TROUBLESHOOTING

Below failures are related to fittings, welding materials, environment factor, and supply power, please try to improve the welding environment.

1. Welding spot become black
   It means the welding spot is oxygenated without good protection, and please check the followings:
   1.1 Make sure the argon cylinder is open and has enough pressure which should be above 0.5 MPa.
   1.2 Make sure the pressure valve is open and has enough flow. In order to save gas, you can choose different flows according to the different welding currents, but it may result in the protective gas can’t cover the welding spot entirely. Argon flow should be not less than 3L/min.
   1.3 The simple method to check whether the argon flows out or not is to feel the gas through a nozzle with your finger.
   1.4 Gas flow is not well sealed or argon is not pure.
   1.5 If the airflow is too strong, it may low down the welding quality.

2. Arc-striking is difficult and easily pauses
   2.1 Make sure the rod or tungsten is of good quality otherwise it is difficult to meet the request of the high-quality welding.
   2.2 It will be hard to strike an arc if the rod is not dry enough or the tungsten is not sharpened. It will also cause unstable arc and the welding quality will be influenced by
   increased defect.

3. Output current not up to the rated value
   Current will not match the setting value when power voltage departs from the rated value. While voltage is lower than the rated value, the max output may be lower than the rated value.

4. Current is unstable during the welding process and it may be caused by the followings:
   4.1 Electric network voltage changes.
   4.2 Harmful interferences from the electric network or other equipment.
   4.3 Undersize the external input cable.

5. Too much spatter under MMA welding
   5.1 High current with a rod of small diameter.
   5.2 The output terminal polarity is reversed. For normal use, you can adopt a positive connection which means the holder connects to the “-” polarity and the work-piece to the “+” polarity, so please exchange.

REPAIR AND MAINTENANCE

Repair and maintenance should be done by a professional person and please make sure the power supply is cut off before any operation. When you meet any insoluble problem please get in touch with us.
Repair and maintenance

1. Check the internal and external circuits of the welding machine regularly and make sure the connections are correct and tight.
2. Avoid water or steam infiltrating the internal machine. If it occurs please dry the machine then check carefully before welding.
3. If the welder will not be used for a long time, please pack it and store it in the dry air.
4. Blowing away the dust with dry clean pressed air regularly, if the welder is used under conditions of dense smoke or polluted air, please clean the machine every day.

Attention: The highest voltage of the machine is above 1000V, please don’t open the machine optionally, electric shock proof should be done during the repair.
