Force System Options
• Gravity ram drop with electrical interlock.
• Air filter with bowl trap and automatic drain.
• 4.50" air gauge calibrated in pounds weld force.
• Adjustable stroke air cylinder.
• Adjustable-retractable stroke air cylinder, foot switch and solenoid valve controlled.
• Special long stroke cylinder.
• Precision air regulator
• Seal-off airlock, single or double pressure with precision air regulator and air tank.
Transformer Options
• High/low tap switch.
• Dual voltage (230/460)
• Special for 50 Hz.
• Special primary voltage.
• Special secondary voltage.
• Special KVA rating.
Drive Options
• Double gear, double knurl or double friction
drive. Double gear drive includes a friction coupling to compensate for the difference in upper and lower wheel diameters. Separate variable speed D.C. drive motors allow easy adjustment to closely match upper and
lower peripheral wheel speeds. This will minimize the slipping required by the friction coupling.
Cooling Options
• Water outlet manifold (except flood water) with flow indicators.
• Internally cooled wheel electrodes.
• Water shut-off solenoid valve.
• Large pan to catch flood cooling water. Convenience Options
• Mounting of welder control, interconnection and system test
• Hydraulic knee jack.
• Motorized vertical knee adjustment.
• Magnetic motor starter.
• 6¼ angle weld heads if required for clearance.
• Special paint.
• Additional instruction books.
• Export boxing.
