♦ 

Select the gun, control cable, and weld cable that is recommended for the specific type of 
welder and the job. 

♦ 

Attach stud gun to weld and control cable extension. 

♦ 

Actuate the stud gun without placing it on the surface to be welded to assure that the con‐
nection through the control cable is correct to complete the circuit and actuate the stud gun. 

♦ 

Make sure welder is set up properly to begin the welding process. 

♦ 

Place the selected stud into the chuck and attach the ferrule to the ferrule grip. 

♦ 

Place stud onto surface to be welded and press stud gun down until ferrule is flush with the 
welding surface. 

♦ 

Trigger the gun and hold in place until cycle is completed.  

♦ 

Pull gun assembly straight up off of the welded stud. 

♦ 

Do not depress trigger when removing gun from stud. 

♦

♦ 

Make proper adjustments as needed.
