Repair kit for the Dehorner III. Portasol are the makers of the original orange gas soldering iron the 'Technic' in 1984. Portasol products are made in Ireland and we manufacture all our own plastic and metal components in our plant in Co. Carlow. Quality has always been the cornerstone of our technology and what gives Portasol the advantage is the added reliability and durability of our tools. Products are tested for 2 weeks before they leave our factory to ensure reliable ignition and adjustable temperature control.
