How to Set Up a Stud Gun for Welding Threaded Arc Studs

WELDER BRANDS:

This setup works for Truweld, Proweld, Midwest Fasteners, Erico, H.A. Jones, and SWS stud welder guns.

STEP 1: Determine the gun adaptor you need.  

 

STEP 2:Determine the ferrule grip you need.   For studs 2" and shorter, use a closed ferrule grip.  For studs longer than 2" use a split ferrule grip. 

 

STEP 3: Determine the arc legs you need.  For most domestic stud welders including Proweld®, Truweld, Midwest Fasteners®, Nelson® NS20, Image and Erico stud welding guns use the 3/8" legs.  For Nelson 30/40 guns, use the 5/16" leg.  

STEP 4: Determine the size arc foot you need.  

  • Small: Stud Size 1/8" - 1/2"
  • Medium: Stud Size 5/8" - 3/4"
  • Large: Stud Size 7/8" - 1"

STEP 5: Determine the type of arc foot you need.  Generally, use a closed foot for stud lengths < 2".  For longer studs use a split foot and ferrule grip to ease loading of the stud into the gun.

STEP 6: Assemble gun
