GYS Stud Arcpull 700 Industry Tool Bags Pouches Bulb: 72 SMD LED Punches tip diamerer 3 Bulb: 72 SMD LED Continuous speed control trigger c w locking function for continuous operation The ARCPULL 700 is a threephase inverter pulled arc welding machine that can weld addons studs internally threaded studs insulation nails pull rings rivet extraction rods etc on aluminum or steelbased materials It has a Synergic operating mode and a Manual operating mode The Programs menu can be used to store and recall welding configurations It has a connection for PLC controlThere are 4 main stages priming stripping arcing and attachmentPriming the addon part pulling ring studs etc is brought into contact with the support sheet Pressing the trigger starts the welding process the generator sends current into the stud the gun axis rises slightly and a lowintensity electric arc is createdStripping this phase could also be called preheating The generator regulates a current to ensure a low intensity electric arc the heat generated by this arc allows to burn the impurities of the support sheet greases oils electrolytic zinc plating to preheat the two parts and therefore to limit the thermal shock of the welding arc in order to improve the quality of the weldDuring this phase neither the insert nor the support sheet melts Similarly this phase does not allow the zinc layer of the galvanized sheet to be releasedThe arc the generator significantly increases the current to create a very energetic arc creating a molten pool on the support sheet and causing the end of the insert to meltThe attachment The gun plunges the insert into the molten pool
