5. Once the machine needs to be repaired , please inform the distributorthe model and product number as soon as possible.NOTICE1. Please confirm the rated specifications and then make use of it.2. Avoid over-load usagea. Serious over-load can burn machine, at least shorten the service life.b..Over-_load may cause noise and make the rotation of hand- wheeldifficult.3. The connection of cable and terminal of machine should be steady .Or it will cause local running hot to burn the terminaI and cable.4. Too long output cable will lead to impedient current circulation and addelectric power loss . If the surface insulation of cable is spoiled , the arewill be unstable . So we need change the old cable in time.5.the power must be switched off after operation .6. The internal movable iron- core sleek structure has been adjusted well.Do not move it if no necessary.7. Place the welder in the shade . Do not use the machine in the sun for along time.8. The temperature of shell will rise in operation . The insulation of windingbelongs to F grade . Please use the machine at rated duty cycle.9. Keep the voltage as stable as possible.The voltage is lower than rated input voltage will lead to(1) The welding current is too low(2) The arc will break or be unstable.The voltage is higher than rated input voltage will lease to(1) The welding current is too high(2) Make noise.(3) The current adjusts the rotation of hand wheel hard .(4) Shorten the service life ot welder.10. Please remember to wear suitable protective apparatus in caseof accident.9PARTS DIAGRAM10
