NOTES OR PREVENTIVE MEASURES

1. Environment

1) The machine should be operated in dry environments with humidity levels of max 90%.

2) Ambient temperature should be between -10 to 40 degrees centigrade.

3) Avoid welding in sunshine or drippings. Do not let water infiter the machine.

4) Avoid welding in dust area or the environment with corrosive gas.

5) Avoid gas welding in the environment with strong airflow.

2. Safety norms

The welding machine is installed with protection circuit of over voltage, over current and over heat. When voltage, output current and temperature of machine exceed the required standard, welding machine will stop working automatically. However, overuse (such as over voltage) will still result in damage to the welding machine. To avoid this, the user must pay attention to the following.

1) 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 inner-machine to cool down machine.

Make sure the intake is not in block or covered, it is 0.3 meter from welding machine to objects of environment. User should make sure the working area is adequately ventilated. It is important for the performance and the longevity of the machine.

2) Do not over load!

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 machine.

3) No over voltage!

Power voltage can be found in diagram of main technical data. Automatic compensation circuit of voltage will assure that welding current keeps in allowable range. If power voltage is exceeding allowable range limited, it will damage to components of machine. The operator should understand this situation and take preventive measures.

4) There is a grounding screw behind welding machine, with a grounding marker on it. Before operation, welding crust must be grounded reliable with cable which section is over 6 square millimeter, in order to prevent from static electricity , and accidents because of electricity 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 fan cool the machine. When the indicator light is off, and the temperature goes down to the standard range, it can weld again.

USER MANUAL - 8 - YF-43L A/0

QUESTIONS TO BE RUN INTO DURING WELDING

Fittings, welding materials, environment factor, supply powers maybe have something to do with welding. User must try to improve welding environment.

A. Arc-striking is difficult and easy to pause

1. Make sure quality of tungsten electrode is high.

2. If the electrode is not dried, it will cause unstable arc, welding defect increases and the quality is down.

3. If use extra-long cable, the output voltage will decrease, so please shorten the cable

B. Output current not to rated value:

When power voltage departs from the rated value, it will make the output current not matched with rated value; when voltage is lower than rated value, the max output may lower than rated value.

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

It has something with factors as following:

1. Electric wire net voltage has been changed.

2. There is harmful interference from electric wire net or other equipment

D. Too much spatter when use MMA welding,

1. Maybe current is too big and stick

’s diameter is too small.

2. Output terminal polarity connection is wrong, it should apply the opposite polarity at the normal technics, which means that the stick should be connected with the negative polarity of power source, and work piece should be connected with the positive polarity. So please change the polarity.

MAINTENANCE

1. Remove dust by dry and clean compressed air regularly, if welding machine is operating in environment where is polluted with smokes and pollution air, the machine need remove dust every month.

2. Pressure of compressed air must be within the reasonable range in order to prevent damaging to small components of inner-machine.

3. Check internal circuit of welding machine regularly and make sure the circuit connections are connected correctly and tightly (especially plug-in connector and components). If scale and rust are found, please clean it, and connect again tightly.

4. Prevent water and steam from entering into the machine. If that happens, please blow it dry and check insulation of machine.

5. If welding machine will not be used for long time, it must be put into the packing box and stored in dry and clean environment.
