How to Set Up a Stud Gun for Welding Headed Concrete Anchors/Shear Connectors (Alternative Method)

WELDER BRANDS:

This setup works for Truweld, Proweld, Midwest Fasteners, Image and Nelson NS20 stud welder heavy and medium duty guns.

ITEMS NEEDED:

STEP 1: Screw the Arc Gun Connector Stud into gun.  The shorter end of the stud is screwed into the gun.

STEP 2: Slide the gun cable eyelet onto the Arc Gun Connector Stud.  Attach the Headed Anchor Chuck into Arc Gun Connector Stud.  Use 2 crescent wrenches to hold the Headed Anchor Chuck when tightening.  Make sure the eyelet stays centered or vertical when it is tightened so the eyelet won’t hang up on the legs later.

STEP 3: Screw the Arc Legs onto the Large Split Foot.

STEP 4: Place the Heavy Duty Ferrule Grip in the Large Split Foot and tighten the set screws.

STEP 6: Place a stud in the Headed Anchor Chuck.

STEP 7: Slide the foot assembly into the gun so that a about 1" of the stud stick out past the Heavy Duty Ferrule Grip.  Make sure the flat side of the legs are towards the set screw on the gun.  Tighten the screws on the gun that hold the legs. 

STEP 8: Adjust the Foot Assembly so that the stud is centered in the middle of the Heavy Duty Ferrule Grip.  Tighten the Arc Leg screws in the foot assembly.

STEP 9: Put a ferrule on the end of the stud and make the plunge adjustment.  The plunge is the amount the stud that sticks out past the ferrule grip not including the flux ball. 

• Loosen the leg screws in the gun.
• Adjust the plunge.
• Tighten the leg screws in the gun.

Weld Thru Deck Recommendation on Determining the Right Plunge:

Grab another stud and slide the foot assembly so that the amount of the stud sticking out past the ferrule grip is equal to the head of the 2^nd stud (3/8”).
