SAFETY INSTRUCTIONS

PRODUCT VALIDITY

STORAGE

Protect yourself and others. Read and understand this information.FUMES and GASES can be dangerous to your health.Arc rays can injure eyes and burn skin.Electric shock can kill.

1. Before use, read and understand the Material Safety Data Sheets (MSDS’s) and safety instructions recommended for welding operations.2. Keep your head out of the fumes.3. Use enough ventilation, exaust at the arc, or both, to keep fumes and gases away form your breathing zone and general area.4. Wear correct eye, ear and body protection.5. Do not touch electrical parts.

Read American National Standard Z49.1, Safety in Welding and Cutting, published by the American Welding Society, 550 N.W.Le Jeune Road, Miami, Florida 33216,USA; OSHA Safety and Health Standards, 29 CFR 1910, available from the U.S. Government Printing Office, Washington, DC 20402.
