Keep Your Welder Safe from the Elements with Miller Electric’s Protective Welding Blanket

Welding can be tough work, and exposing your welder to the outdoor elements makes it even tougher. Rain, snow, wind, dust, and debris can damage your expensive welder, reducing its lifespan and effectiveness. That’s why Miller Electric designed the 300379 Protective Welding Blanket – to keep your welder safe from the harsh outdoor environment.

This heavy-duty PVC welding blanket measures a spacious 54” x 84” to cover even large welders completely. The thick 18 oz vinyl material is durable, flame retardant, and waterproof to block moisture, dirt, sparks, and spatter. Integrated magnets allow you to securely attach the blanket around your welder. A complete perimeter hem with grommets let you tie the cover down for a tight, weatherproof seal.

Keep Your Equipment Safe and Working Its Best

You work hard to grow your business and serve your customers. The last thing you need is downtime from welder failure due to neglect. This protective blanket ensures your equipment stays in peak operating condition, job after job.

Miller Electric made sure this blanket is quick and easy for welders to use. Just drape the cover over your equipment and secure the integrated magnet seams. The strong magnets ensure the blanket forms a tight seal around your welder without gaps.

The grommeted perimeter hem allows you to tie the cover down for an extra-secure fit. When you’re ready to weld, simply remove the cover and store it safely until the next use.

The 300379 blanket is designed to be universal – fitting a wide range of welder types, sizes, and brands. Measuring 54 inches wide by 84 inches long, the blanket is large enough for everything from small portable welders up to large, heavy-duty industrial models.
