Excalibur®11018M MR
Basic, Low Hydrogen, Low Alloy Steel SMAW Electrode
(AWS E11018M-H4R)
Excalibur®11018M MR™is designed primarily for joining high strength steel types in the aswelded or stress relieved conditions with excellent low temperature impact properties and
robust welding procedures. All-position welding, except vertical down.
Advantage Lincoln
Integrated Silicate Technology™
Increased moisture resistance and decreased coating fragility.
Easy Strike™ Tip
Consistent, smooth arc starts.
Square Burn-Off
Focused arc for hard to access welds.
X-Ray Quality
Demanding applications.
Hermetically Sealed Packaging – Easy Open Cans
Delivers quality product, performance reliability and
consistent results.
ISO 9001 and 14001 Certified
Manufactured to standards for environmental and quality
management systems.
