Murex Fortrex

A basic coated hydrogen controlled electrode designed for all positional welding (except vertical down) of carbon and medium tensile steels and mild steels under conditions of high restraint. The electrode is intended for general fabrication work where hydrogen control is required – this electrode guarantees values below H4. An iron powder addition is included in the coating, this gives a weld metal recovery of approximately 120%. Striking and re-striking qualities are good and slag is easily removed from the weld.
