Preface This manual includes hardware description and operation introduction of the equipment. For your and other people’s safety, please read the manual carefully. Pay attention Pay attention to the words after the signs below. Sign Description The words after this sign means there is great potential danger, which may cause major accident, damage or even death, if it is not followed.
Never weld airtight containers such as slot, pipe etc., or it may break. Arc ray may cause eye inflammation or skin burnt. Spark and residue will burn your eyes and skin. Toppling over of the gas cylinder will cause body hurt.

The machine is portable, never lift it by any equipment. Please follow the rules below to avoid heavy accidents. Never use the equipment to do other things but welding. Follow related regulations for the construction of the input-driven power source, choice of place, usage of high-pressure gas, storage, configuration, safe-keeping of workpiece after welding and disposal of waste, etc.

Before the installation, please estimate the potential electromagnetism problems of the environment as follows. a) Upper and lower parts of the welding equipments and other nearby power cable, control cable, signal cable and phone cable. b) Wireless electric as well as TV radiation and reception equipment. c) Computer and other control equipments.
The welding power source can offer stronger, more concentrated and more stable arc. When stick and work piece get short, its response will be quicker. It means that it is easier to design into welding machine with different dynamic characteristics, and it even can be adjusted for specialty to make arc softer or harder.
“+” terminal. Negative connection: work piece with the“-” terminal, holder with the “+” terminal. Choose suitable way according to the working situation. If unsuitable choice is made, it will cause unstable arc, more spatters and conglutination. If such problems occur, please change the polarity of the fastening plug.
OPERATION INSTRUCTION Turn on the power switch, the power led lights up. Adjust knobs of welding current and arc-striking push, make welding function complies with demands. Generally, welding current is adequate to welding electrode according with as following: φ2.5 φ3.2 φ4.0...

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 inter the machine. 4)...
1. Make sure quality of 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.
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.
TROUBLE SHOOTING AND FAULT FINDING Notes: The following operations must be performed by qualified electricians with valid certifications. Before maintenance, please contact with us for professional suggestion. Faults symptom and solutions Faults symptom Solutions Power indicator is not lit, Make sure power switch is close. fan is not working, no Make sure the electric wire net connecting to input cable is working welding output.
