Hobart 418 Mild Steel Low Hydrogen Stick Electrode - E7018-1 H4R - 1/4" X 18" - 50 lb Can - S119981-035

Hobart 418 is a general purpose electrode that allows you to tackle a wide variety of welding projects with ease. You will get superior weldability from this low hydrogen, mild steel electrode that provides you with excellent start and restart capabilities in addition to a smooth and virtually spatter free arc. Hobart 418 has a very flat bead shape with a fine ripple appearance.  The weld puddle smoothly washes into the sidewalls with no undercut. Slag removal is one of the best and in many cases is self-peeling. Hobart 418 also has the ability to operate smoothly even when the welding surface is somewhat dirty or rusty.  Hobart 418 is designated as a low moisture absorbing product and can be exposed to higher temperatures and humidity for over 8 hours and meet AWS requirements. Extremely high impact levels are available with Hobart 418 even at -50°F giving the 418 its AWS E7018-1 designation.
