Typical Chemical Composition
Typical all-weld-metal analysis (wt %). Single values are maximums; iron is the balance.
Recommended amperage ranges are general guidelines; optimal settings vary with base-metal thickness, joint design, shielding gas, and welding position. Store wire in a dry location to prevent oxidation and ensure smooth feeding.
WARNING
This product can expose you to chemicals including manganese, which is known to the State of California to cause birth defects or other reproductive harm. Welding fumes from this product can also expose you to chemicals known to cause cancer. For more information go to www.P65Warnings.ca.gov.
