Drying Furnace For Welding electrode

Specifications

for basic type, stainless steel type, cover of welding electrode, cast iron, heat resistant steel, welding electrode

This oven is mainly used for continuous drying at low, middle, high temperature for basic type, stainless steel type, cover of welding electrode, cast iron, heat resistant steel, iron powder and other special type of welding electrode after drying at low temperature. It also can be used to dry common steel carbon welding electrode.
