IMPORTANT: SPECIAL VENTILATION AND/OR EXHAUST REQUIRED
Fumes from the normal use of some welding products can contain significant quantities of components - such as chromium and manganese - which can lower the 5.0 mg/m3 maximum exposure guideline for general welding fume.
BEFORE USE, READ AND UNDERSTAND THE MATERIAL SAFETY DATA SHEET (MSDS) FOR THIS PRODUCT AND SPECIFIC INFORMATION PRINTED ON THE PRODUCT CONTAINER.
(1) Composition and properties depend upon dilution. Single layer deposit properties depend upon base metal and/or build-up material.
(1) 802 and 860 standard flux are not sized for semiautomatic applications; however, they can be ordered in special sizing by
contacting your Lincoln Electric representative.
