Nelson SBA shoulder studs have a weld base diameter larger than the threaded extension diameter. They are available in weld base diameters 1/4” through 1/2”, with threaded extension sizes up to 7/16-14. The Nelson SBL studs are used as mountings for panels and hardware where a standoff shoulder is needed. SBA studs are similar to CKA aluminum collar studs, but the larger weld base provides improved bend resistance. Both chuck size and part number are determined by the thread size, C. Please refer to the Nelson HBA stud specification sheet to find the appropriate chuck size and number.
Nelson SBA studs are welded using ceramic ferrules in conjunction with argon as a shielding gas. The shielding gas is introduced through a gas foot assembly, #751020000, which is used for all diameters of SBA studs. Gas hose #515001001 and a gas regulator #514001001 are needed to deliver and control the gas flow from a pressurized cylinder. An aluminum Tranquil-Arc plunge dampener kit is also needed as an accessory on the gun to control the rate of the stud’s return to the molten weld metal at the end of the weld cycle.
