3M SecureFit 3700 Welding Safety Glasses

The 3M SecureFit 3700 series welding safety glasses are designed for professionals who require reliable eye protection during welding tasks. They feature an IR 3.0 shade lens that filters infrared radiation while maintaining clear visibility. The frameless, universal-size design fits a wide range of users and is compatible with over-the-glass wear. These glasses suit industrial environments where optical clarity and impact resistance are essential.

Anti-scratch polycarbonate lens with UV protection

The polycarbonate lenses provide 99.9 percent UV protection and include a scratch-resistant coating to extend optical clarity over time. The frameless construction reduces weight and pressure points during extended wear. Pressure-diffusion temples distribute force evenly across the head to minimise fatigue. The clear frame and black temples offer a neutral appearance suitable for any workspace.

OTG frameless design for flexible integration

The over-the-glass frameless style allows the glasses to be worn comfortably over most prescription eyewear without additional clips or adapters. Universal sizing eliminates the need for multiple stock-keeping units across a workforce. The polycarbonate frame material withstands impact while remaining lightweight. This design frees up facial space for respirators or other head-mounted personal protective equipment.

Questions about this item

How do I install the 3M SecureFit 3700 welding glasses and what step is often missed?

Put the glasses on so the frameless polycarbonate lenses sit squarely in front of each eye, then push the black pressure-diffusion temples back until they rest evenly on both ears; the step people skip is checking that the clear frame touches the brow without gaps so the IR 3.0 filter covers the full field of view.

What maintenance or replacement will the 3M SecureFit 3700 welding glasses need later?

Inspect the scratch-resistant polycarbonate lenses before every shift; replace the unit immediately if any lens shows pits, deep scratches, or coating wear that reduces the 99.9 percent UV protection, because the frameless design has no replaceable parts.

What limit appears first when the 3M SecureFit 3700 welding glasses are used continuously?

The fixed IR 3.0 shade transmits a set amount of infrared; if the welding process generates infrared intensity beyond what that shade attenuates, the wearer feels heat on the eyes before any mechanical failure of the polycarbonate frame or temples occurs.
