Duro Dyne’s MF has been the standard for entry level “through insulation” welders for over 30 years. Proven performance and high reliability have made the MF a “Must Have” for any sheet metal shop which does occasional insulating.

Duro Dyne now introduces the MF-12A, building on that history, and creating a new pinspotter with greater power and versatility. Special design welding transformers allow the MF12A to deliver more power, precisely timed to the welding tip. The MF-12A will weld pins from ½ inch to 4 inches long on steel from 26 to 20 gauge. Proven solid-state weld control circuitry guarantees years of reliable, troublefree service in your shop.

The latest breakthrough from the innovators of insulation fastening is the FPP4, a pinspotter platform that enhances the capabilities of a compact pinspotter. The FPP4 works in conjunction with the Duro Dyne MF12A/MF12 compact pinspotter (sold separately) to allow it to be utilized as both a hand held pinspotter and a fixed head pinspotter. This provides the customer with greater capabilities at a lower cost. The FPP4 requires 110 volts and 80 PSI in addition to the power required by the MF12A (208-230 VAC single phase with 60 amp circuit protection). Please note the FPP4 will not work if not powered by an MF Pinspotter.

The CCD110, Capacitor Discharge Welder, is designed for the convenience and comfort of the operator. It is powered by a 110 volt power source so it is ideal for smaller shops and light industrial applications. It will weld pins from ½” to 4” long onto steel from 26 to 20 gauge. Its portability on the job, enhanced by its adjustable shoulder strap, makes the CCD110 a smart choice for insulation applications. The CCD110 also features a stud capacity of up to ¼” steel and stainless steel for enhanced versatility.
