- 12 -6. NECESSARY POWER SOURCE EQUIPMENT6.1 Welding Power Source Equipment (for commercial use)WARNINGᙀWhen the welding machine is used in a humid environment such as a construction site, on asteel plate, or on a steel structure, install a leakage breaker.CAUTIONᙀBe sure to install a switch with fuse or a circuit breaker (for motor) to the input sides of eachwelding machine.Capacity of Necessary Power Source UtilityAC-TIG DC-TIG STICKPower supply voltage 400 V, three phaseTolerance range of fluctuation of powersupply voltage 400V±15%Installed capacity 12.5kVA or more 11.9kVA or more 13.2kVA or moreCapacity of switch/circuit breaker 50 A 50 A 50 A6.2 Precautions for Use of the Engine GeneratorCAUTIONᙀUse the auxiliary power of engine welder with an improved voltage waveform. Some enginewelders have poor electricity, which may cause product damage. Contact an engine weldermanufacturer for improvement of voltage waveform.To prevent the welding power source from being damaged because of engine generator, follow theinstructions below.ᙀSet the output voltage of the engine generator to the voltage range between 400 and 420V atno-load welding operation. Setting to extremely high output voltage may result in product damage.ᙀUse an engine generator with a damper winding that has a capacity of more than twice that of therated input of the welding power source. Generally, the recovery time of the engine generator’svoltage for load change is slower than that of the commercial input power source, and if the enginegenerator does not have sufficient capacity, sudden current change such as arc start will occur.This may cause abnormal decrease in output current or arc loss. Ask an engine generatormanufacturer for a damper winding.ᙀDo not combine more than two welding machines with a single engine generator. The effect ofeach welding machine may cause easy loss of arc. |
