How to use: Put on the welding jacket before starting your welding work. Make sure to adjust the snaps on the collar and cuffs for a comfortable fit. You can keep your small valuables in the inside pocket. Note: Only use this jacket for the recommended welding processes (MIG, Stick, TIG, Flux-Core) and within the amperage range of 50A - 400A. Avoid exposing the jacket to extreme heat or sharp objects that could damage it. Maintenance: The jacket is machine washable. Follow the regular washing instructions to keep it clean. After washing, let it dry naturally. Don't use harsh chemicals or bleach as they may reduce the flame-retardant properties.
