Duro Dyne markets a full compliment of the finest quality tools for the sheet metal tradesman. Constant testing and evaluation ensures Duro Dyne continue to supply high quality products to the industry. The LF is a portable unit (9 lbs.) that welds 14 gauge PN style pins to ductwork up to 22 gauge. Insert a PN Pin into the magnetic tip and depress the trigger. A timed burst of electricity fuses the pin to the steel. It can also weld LN style pins up to 5-1/2” long with the use of a TPL2 tip purchased separately. Available in 110v & 220v, 50 to 60hz; fuse for 15 amps. 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 insulating. Duro Dyne now introduces the MF-12, building on that history, and creating a new pinspotter with greater power and versatility. Special design welding transformers allow the MF12 to deliver more power, precisely timed to the welding tip. The new MF-12 will weld pins from ½ inch to 2 inches long on steel from 26 to 20 gauge. Proven solid-state weld control circuitry guarantees years of reliable, trouble free service in your shop.
