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.
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.
6. When moving the welding machine, be careful not to be injured by the machine. If you need to lift the machine, do not stand in the space under the machine
to reduce the risk of an accident.
WELDING
Fittings, welding materials, environment factor, supply powers maybe have something to do with welding. User must try to improve welding environment.
A. Arcing-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.
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 machine is been operating:
1. Electric wire net voltage has been changed.
2. There is harmful interference from electric wire net or other equipment.

MAINTENANCE

Caution: Always disconnect the power supply before carrying out any maintenance or inspection. Make sure that the mains plug is disconnected before
opening the housing of the device.
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 everyday.
2.Pressure of compressed air must be inside the reasonable arrangement in order to prevent damaging to small components of inter-machine.
3. Check inter circuit of 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.
4. Avoid water and steam enter into inter-machine, if them enter into machine.Please dry inter-machine then check insulation of machine.
5. If welding machine will not be operated for a long time, it must be put into package and stored in dry environment.
Caution: It is recommended that only a qualified technician tests and attempts repair on this high voltage machine. Incorrect diagnoses or repair may lead
to serious injury or death!
