Dual Gun Torque Converter Welder

Torque Converter Rebuilding Systems

Jump to Section


Volume remanufacturing requires the highest level of throughput so TCRS® offers the dual gun welder for maximum productivity. It features two Miller® Invision™ 352 MPa power supplies and two 74 Series wire feeders for double the output rate of the single gun welder. Automatic torch indexing sets the welding torches in place, 180 degrees from each other, a time saving feature for high output converter shops. Like the single gun, the dual gun welder automates the critical phases of precision alignment and seamless welding of remanufactured torque converters. Air-operated collets along with patented auto-tack and auto-weld functions come standard and, like the single gun welder, it performs bowl build ups and can weld impeller hubs and ring gears. Like all TCRS® products, precision aligned fixtures and spindles ensure unmatched accuracy while proven manufacturing practices produce a rugged and reliable machine built for years of service.

TAC-12D Included

The included TAC-12D digital control panel lets you determine the number (4,6,8,12) and duration (50-3000 milliseconds) of each tack weld and also controls both the auto-tack and auto-weld cycles. JOG control rotates the table without welding and LCD display shows tack time, table speed and counts along with the ability to edit all control settings. The TAC-12D is available as a retrofit to existing single & dual gun welders.
