performing maintenance work or repair work, provide Installing shielding (curtain etc.) fence or the like around the welding machine so that unauthorized person can not come close carelessly. Arc flash, flying spatter, slugs, and Welding wire noise generated during welding can damage your eyes, skin and hearing.
Notice: In order to get better performance and provide proper maintenance, please follow the below instructions: 1 If welding machine is placed on a slope, a countermeasure should be taken to keep it from falling on one side. 2 The degree of protection is IP21S, appropriate coverage is required in case of rain. 3 When using forklift, please fork welding machine at the side with “Fork”...
Table 5.2 Output current (A) Cable (m) Cable (mm 5. Remark: The length of welding cable=the length of electrode holder+ the length of base metal cable (2) Grounding □ Keep well grounding, would prevent form electric shock and misaction of equipment caused by high- frequency electric wave generated by power source controller.
2. Power display lamp-------------Will light when turn on the power switch. 3. Welding current adjustor-------Regulates the welding current. 4. Arc force current adjustor------Regulates the arc force current. 5. Arc start current adjustor-------Regulates the arc start current. 6. Warning lamp of over-temperature---Will flicker onece every one second and no output with the abnormal temperature.
Please connect the output cable (electrode holder) to the end of ORDI. STICK (+), when welding with the ordinary electrode just as Fig.7.1a. Please connect the output cable (electrode holder) to the end of CEL. STICK (+), when welding with the cellulose-coated electrode just as Fig.7.1b.
1. Electric connection Check the bolts whether fasten and the ill-insulation both in the input side and output side. 2. Is there any hot evidence in the connection between the cables? Make sure that the power source grounding firmly. 3. The inside of the power source If the radiator is covered by a lot of dust, it won’t emit hot unhindered that may be bad for semiconductor or transistor.
11. Check points for abnormal operation Table 11.1 Abnormity Cause of warning Countermeasures Power lamp doesn’t light * The shortage of U or V phase in the * Check out the cause of and no output after the power supply the short voltage-phase.
