TIG torch water-cooled adapter kit
This adapter kit connects Lincoln Electric PTW-18 and PTW-20 water-cooled TIG torches to compatible Lincoln power sources. It provides the Twist Mate style connector required by the listed welder models. The kit is sold new and contains the parts needed for that specific torch-to-machine interface.
Suits owners of listed Lincoln welders.
Welders who own a Lincoln power source such as the K1478-5, K1728-12, K1728-13, K1728-5, K1728-6, K1845-1, K2403-2, K2437-2, K2533-2, K2534-1, K2535-1, K2535-2, K2675-2, K2774-2, K2774-4, K3945-1, K3946-2, K4023-1, K4023-2 or K5126-1 and who use PTW-18 or PTW-20 torches can install this kit. It will not fit air-cooled torch models or torches from other manufacturers that use a different connector style.
Twist Mate connector type decides compatibility
The single specification that determines fit is the Twist Mate adapter type combined with the water-cooled PTW-18 and PTW-20 torch series designation. Only power sources explicitly listed for those torch models will accept this connector.

Questions about this item
Does the PTW-18 adapter kit generate any heat or electrical noise during extended welding runs?
The adapter is a passive mechanical connector with no active electronics, so it produces no electrical noise and negligible heat beyond normal conduction from the torch cable.
What welder output fitting must I already have on my machine for this Twist Mate kit to connect?
Your power source needs a Twist Mate compatible receptacle; the kit is designed for Lincoln models such as K1478-5, K1728-12, K1728-13, K1728-5, K1728-6, K1845-1, K2403-2, K2437-2, K2533-2, K2534-1, K2535-1, K2535-2, K2675-2, K2774-2, K2774-4, K3945-1, K3946-2, K4023-1, K4023-2, K5126-1.
Will the PTW-18 adapter work with my older PTW-20 water-cooled torch without modification?
Yes, the kit is listed for both PTW-18 and PTW-20 series water-cooled torches, so an existing PTW-20 torch connects directly.
