* Arc current is limited to 100A when the product is connected to a 110Vac 50Hz/60Hz power supply.
Ignition : the insert (pull ring studs, etc.) is placed in contact with the supporting material. Pressing the trigger starts the welding
process: the power source sends current to the stud, the gun shaft rises slightly, A low-intensity electric arc is then created.
Penetration and cleaning: This phase could also be called preheating. The power source regulates a current to ensure a low-in-
tensity arc, the heat generated by this arc allows:
- burning off impurities from the backing sheet (grease, oil, electrolytic zinc coating).
- to preheat the two pieces, and thus limiting the thermal impact of the welding arc, to improve the quality of the weld.
During this phase neither the insert, or the support plate, is melted. Also, this phase does not allow the zinc layer of a galvanised
plate to be removed.
The arc: the power source significantly increases the current to create a high-energy arc that creates a molten pool on the support
plate and causes the end of the insert to melt.
Binding: The gun plunges the insert into the molten weld pool.
4. STUD DESIGN AND WELD POOL PROTECTION
The different types of inserts (shape, dimensions, material) designed for the drawn arc process are listed in the ISO 13918 stan-
dard. In addition to low carbon steel inserts, in stainless steel and copper-plated steel, the product can also weld certain aluminium
inserts.
4.1. SURFACE CONDITION OF THE WORKPIECE AND CLEANING
Welding of inserts must be carried out on a grease-free workpiece. It is also necessary to strip this workpiece if
it has a chemical treatment (zinc coating for galvanised steel, anticorrosive for heat-treated steels, alumina for
aluminium).
The welding of the insert especially aluminium parts, must be carried out on a flat support surface.
