Stanley Engineered Fastening, a global provider in precision fastening, is offering the N550c Arc Charger for sale or rent. It is the first of a new class of stud welding power sources developed around Nelson’s patent-pending Arc Charger platform.
The N550c Arc Charger is a compact and portable power unit that welds studs onto workpiece surfaces designed for the construction, industrial, and shipbuilding industries. It has the capacity to weld the full range of drawn arc studs, up to 3/8″ pitch (M8) diameter, with an ultra-smooth, high-speed switching welding arc.
To do so, it only requires power from a standard household 120V wall outlet.
The Arc Charger is a stud welding system designed to use both the drawn arc and short-cycle weld process.
The drawn-arc method uses fasteners with integrated flux balls in conjunction with ceramic ferrules. The flux ball on the tip of the stud acts as a deoxidizing agent during the weld. The ceramic ferrule contains the molten metal in a consistent shape around the weld. The short-cycle method uses fasteners without a flux ball and does not require a ceramic ferrule.
With the exception of shorter weld time, the operational sequence is identical to the drawn arc method. The extremely short weld times of the short-cycle method mean the studs can be welded without ceramic ferrules.
This breakthrough combination enables high-strength drawn arc stud welding in nearly any location without the need for high-voltage, industrial, three-phase power or a large generator.
