SHORT CYCLE / DRAWN – ARC STUD WELDER

What is Short Cycle/ Drawn - Arc Stud Welding?

Short Cycle/ Drawn Arc Stud Welding is commonly known as ‘Short Cycle Stud Welding’ or ‘SC Welding’. The Short cycle is similar to drawn arc stud welding in many aspects, as it requires three-phase power and a 415-volt power supply.

The Short cycle stud welding is a faster form of the drawn arc stud welding process for attaching metal studs and other fasteners to metal sheets. Short cycle welding is an abbreviated version of the drawn arc stud welding process which involves weld studs that are 3/8″ and smaller and surfaces which are thinner in diameter. It also offers the shortest welding times of all the drawn arc stud welding alternatives.

Short Cycle method is effective and suitable to use on slightly broad sheet metals that are uneven or have imperfections.

How Short Cycle Stud Welding Works?

• • Pre-set the weld time and current according to the stud diameter.
• • Place the stud on the parent material.
• • Press trigger and the stud lifts off the base material, drawing an arc. The arc dissolves the end of the weld stud and the base material underneath.
• • The process times out and the main current is shut off. Return pressure forges the stud and molten pool. There is no requirement of the ferrule to shape the fillet.
• • The weld is now complete and the resulting weld bond develops the full strength of the fastener in the weld zone, now you can pull the hand tool off the stud.
