MapleWeld E40 Dirty Cast Iron Stick Welding Electrodes

MapleWeld E40 ensures flawless cast iron welding with a nickel-cored electrode and specialized coating, delivering pore-free welding on grey and malleable cast iron — even on surfaces contaminated with oil. The pulsating welding technology alternates between a heat-generation phase and a droplet-projection phase, burning out oil and grease for effective slag removal while giving superior control over porosity. Controlled heat input allows a slower cooling rate on the first pass for a soft, machinable deposit without undercutting, and the all-positional design works with both A.C. and D.C. welding.

Key Features

  • Nickel-cored electrode with specialized coating for pore-free welds
  • Effective on grey and malleable cast iron, even oil-contaminated surfaces
  • Pulsating arc burns out oil/grease and controls porosity
  • Controlled heat input for a soft, machinable, undercut-free deposit
  • All-positional welding, compatible with A.C. and D.C.
  • Five rods per telescopic translucent plastic case

Applications

Ideal for welding cast iron requiring leak-tight, machinable results — including cracked motor blocks, pump housings, gear wheels, rebuilding lathe beds, and valve seats.
