Install the configuration
The welding equipment is equipped with power voltage compensation set. When power voltage changes between±15% of rated voltage, it still works normally.
When using long cable, in order to minimize the reduce of voltage, big cable is suggested. If the cable is too long, it will affect the performance of arcing and other system function, so stated length is suggested.
1Make sure the intake of the machine is not covered or blocked to prevent the malfunction
of the cooling system.
2 Use earth cable that the section no less than 6mm2 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 power switch reaches the earth. Both ways can be used for better security.
Installment ,when use gas welding (solid wire)
1) Connect the gas bottle with CO2 regulator flow meter and the Input Gas Connector behind the machine via gas hose.
2) Insert the cable connector of earth cable into the socket in the front panel. 3) Set the welding wire spool on the wheel axis, the wheel hole should be matched with the
wheel fixer. 4) Choose wire slot according to wire size. 5) Loosen the screw of wire-pressing wheel, put the wire into slot via wire-lead tube, tune the
Wire-pressing wheel to fix wire from gliding, but pressure should be suitable in case the wire distorts and affects wire sending. 6) Wire roller should turn clockwise rotation to let out wire, to prevent wire from gliding; 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. 7) The MIG torch has been settled inside of the machine just need put the wire into the torch by hand.

NOTES OR PREVENTIVE MEASURES
1Environment
1) The machine can perform in environment where conditions are dry with a dampness lever of max 90%.
2) Ambient temperature is between 10 to 40 degrees centigrade. 3) Avoid welding in sunshine or drippings. 4) Do not use the machine in environment where condition is polluted with conductive dust
on the air or corrosiveness gas on the air. 5) Avoid gas welding in the environment of strong airflow.
2Safety norms
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 automatically. Because that will be damage to welding machine, user must pay attention as 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 intermachine 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 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 millimeter I order to prevent from static electricity and leaking.
– 15 –

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.
QUESTIONS IS BE RUN INTO IN WELDING
Fittings, welding materials, environment factor, supply powers maybe have something to do with welding. User must try to improve welding environment.
AArcing-striking is difficult and easy to pause
1) Make sure the earth cable clincher connects the work piece well. 2) Check each connecting point connected or not.
BOutput 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.
CCurrent 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 Welding gap has air hole. 1) Check the gas supply loop leaks or not. 2) Surface of mother material has oil, stain, rust, lacquer or other impurity.
