OVERVIEW

Product Overview

The ArcOne UML-300 Universal Mag Lens is an optical accessory designed to enhance visual clarity for welding professionals. Featuring a magnification strength of 3.00 diopters, this lens is engineered to assist operators in viewing the weld puddle, arc, and joint with greater precision. It is particularly beneficial for applications requiring tight tolerances or for operators with presbyopia who require vision correction to maintain optimal weld quality.

Universal Compatibility

A key engineering feature of the UML-300 is its universal form factor. The lens is manufactured to the industry-standard dimensions of approximately 2 inches by 4 inches, allowing it to interface seamlessly with the rear cover plate retention systems of most welding helmets. Whether the helmet utilizes a vertical or horizontal mounting bracket, the UML-300 is designed to fit securely. This cross-compatibility covers a wide range of manufacturer 5x4 and 4x5 inch welding helmet assemblies, making it a versatile stock item for tool cribs and individual operators alike.

Optical Performance and Safety

Constructed from high-quality optical materials, the lens provides consistent magnification across the viewing area with minimal distortion. This clarity is critical for identifying minute defects, ensuring proper fusion, and controlling the heat-affected zone during intricate TIG or low-amperage MIG processes. By integrating the magnification directly into the helmet's viewing stack, the user eliminates the safety risks and ergonomic issues associated with wearing corrective spectacles, such as slippage, fogging, or interference with the helmet's seal. The lens is lightweight, weighing approximately 0.176 lbs, ensuring that it does not compromise the balance or comfort of the headgear during extended use.

Installation and Maintenance

Installation of the UML-300 is straightforward, requiring no tools. It typically replaces the standard clear rear cover lens or is inserted into the dedicated magnification slot found on many auto-darkening filters (ADF). Maintenance involves standard lens cleaning protocols using non-abrasive cloths and mild cleaning solutions to preserve optical clarity and prevent scratching.

FAQ

The diopter rating indicates the magnification strength of the lens. A 3.00 rating is relatively strong, similar to a strong pair of reading glasses, providing significant magnification for close-up work.

The UML-300 is designed with standard 2x4 inch dimensions, making it compatible with most welding helmets that have a retaining frame for a rear cover lens or a dedicated cheater lens slot.

Installation is simple: open your helmet's lens cartridge assembly and slide the mag lens into the retention clips on the inside of the helmet, closest to your eyes. It typically sits behind the auto-darkening filter.

Yes, you can wear contact lenses. However, since the mag lens provides magnification similar to reading glasses, you should ensure the combined correction is appropriate for your vision needs to avoid eye strain.

The ArcOne UML-300 is typically manufactured from optical-grade polycarbonate, which is lightweight and impact-resistant, though it should still be protected from scratches.

No, this lens is an accessory for vision correction. You should still maintain your standard inside and outside safety cover lenses to protect the auto-darkening filter.

While you can look through it while grinding, the magnification might distort your depth perception at distances further than your welding focal point, so it is generally recommended for welding tasks.

Clean the lens with a soft, lint-free cloth and a mild lens cleaner or soap and water. Avoid abrasive cleaners or rough paper towels that could scratch the surface.
