Ferrocraft 21 is a popular rutile type, medium iron powder electrode. It offers many features including smooth stable AC / DC running on low O.C.V. welding machines, excellent fillet shapes in all welding positions (including vertical - down/up and overhead) and a higher electrode efficiency of 110%. It is suitable for workshop or ‘on-site’ repair, maintenance and fabrication welding jobs where the iron powder addition gives improved usability over conventional E4112 rutile type electrodes.
