E70T-4
Alloy Type: A5.20, CARBON STEEL Flux Cored Arc Welding Electrodes
E70T-4 is a self-shielded, flux cored electrode designed for use in the multiple pass welding of carbon steels. This electrode is intended for flat position welding of grooves and fillets and horizontal fillet welding with extremely high deposition rates.
Typical Applications: ideal for those welding applications where gas-shielded electrodes may have problems, such as outdoors or in windy conditions; good choice in poor fit up situations or when extended stickouts must be used in hard-to-reach areas.
