Car-O-Liner has released the AW-Tong, a water-cooled, fully automatic welding accessory designed for the CTR9 resistance spot welder to access restricted weld areas that cannot be reached using standard C-arms.
The accessory was introduced on July 20 by Car-O-Liner, a collision repair equipment brand under Snap-on Inc. The AW-Tong integrates directly into existing CTR9 systems, utilizing the welder’s established parameters and maintaining the standard operational workflow without modification.
When operated in automatic mode, the accessory executes a self-calibration sequence prior to welding. It then detects the material type and thickness, determines the corresponding welding parameters, and logs the execution data through the primary CTR9 control unit.
“With the AW-Tong, we have combined the speed and precision technicians expect from the CTR9 platform with a water-cooled, fully automatic system that keeps pace with high-volume bodyshop production,” said Doug Bortz, manager of collision sales for Car-O-Liner in North America. “The swivelling, ergonomic handle lets a technician hold the tool in a comfortable position regardless of the repair angle, while calibration, thickness measurement and parameter selection are completed automatically.”
The AW-Tong utilizes an alternative electrode configuration relative to standard CTR9 C-arms, facilitating access to clearance-constrained structures. The integrated liquid cooling system is engineered to prevent overheating during continuous, high-duty-cycle operation and to ensure uniform weld execution.
