Ground Blocks

FOR ALL MIG & ARC WELDING APPLICATIONS IN FIXTURES, TRUNNIONS, AND DIAL TABLES. INSULATED GROUND BLOCK CYLINDERS ARE IDEAL FOR SINGLE-POINT WELDING.

  • GB Series Ground Blocks produce a consistent pressurized ground even after significant electrode wear. Increases weld consistency. Eliminates commutator grounds on trunnions.
  • Retractable ground blocks allow easy part removal or transfer. Cylinder rod is electrically insulated from body. Solid state tie rod mounted switches available. Standard copper shunt adaptor allows easy shunt connection.
  • Cost savings over machined backups/ground blocks

GB3 Ground Block Retract Cylinder

Ideal for turntables, trunnions, framing and cradle lines, seating applications

GB3 is pneumatically actuated, available in four retract stroke lengths to allow easy part removal or transfer. Part contact pressure can be adjusted with an inline regulator. Ideal for single-point welding and dial tables. Commutator grounds are eliminated on trunnions. Lube-free design, double seals, and chrome-plated shafts. Optional Class 2 copper adapter with a variety of swivel tips.

Strokes: 25, 32, 50, 75, 100mm
Cylinder: 70mm bore, optional switch
