The ARCPULL 350 is a singlephase inverter pullarc welding machine for welding inserts studs internally threaded studs insulation nails pull rings rivet extractors etc onto aluminum or steelbased materials It features a Synergistic operating mode and a Manual operating mode The Programs menu allows you to store and recall welding configurationsThe process consists of four main stages ignition pickling arc and strikeIgnition The insert pull ring stud etc is brought into contact with the base plate Pressing the trigger starts the welding process the generator sends current to the stud the gun shaft rises slightly and a lowintensity electric arc is createdPickling This phase could also be called preheating The generator regulates the current to ensure a lowintensity electric arc The heat generated by this arc allows the burning of impurities on the base plate grease oil electrolytic zinc plating the preheating of both parts thus limiting the thermal shock of the welding arc in order to improve weld qualityDuring this phase neither the added part nor the base plate melts Similarly this phase does not allow the zinc layer on galvanized sheet metal to be removedThe arc the generator significantly increases the current to create a very energetic arc creating a molten pool on the base plate and causing the end of the added part to melt
