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