Welding auto-darkening helmet Sefa Verlag LXBW148 with adjustable filter, solar cell and CR2450 battery

The Sefa Verlag LXBW148 welding auto-darkening helmet provides adjustable eye and face protection for a range of arc welding tasks. The helmet features an auto-darkening filter with variable shade control, enabling the user to set the tint appropriate to the welding process. Power is managed by a combination of a solar cell and a CR2450 backup battery to ensure continuous filter operation during work. The lightweight shell and ergonomic design support use in fabrication, repair and maintenance settings where reliable arc protection is required.

Advantages

The adjustable auto-darkening filter allows precise shade selection for MIG, MMA and TIG welding, reducing the need to switch helmets or flip a passive lens. Integrated solar power extends operating time while the CR2450 backup battery ensures the filter remains functional in low-light conditions. The helmet’s design provides full face and eye coverage, helping to protect against sparks, spatter and harmful radiation while maintaining a clear view when not welding.

Suitable for

• MIG and MAG welding in workshop and construction environments
• MMA/stick welding for maintenance and repair tasks
• TIG welding where variable shade and sensitivity are required
• General metal fabrication, assembly and on-site maintenance work

Key specifications

• Auto-darkening filter with adjustable shade control suitable for a range of welding currents and processes
• Power system combining a solar cell with a CR2450 backup battery for continuous operation
• Full face and eye coverage with lightweight helmet shell for extended use
• Sensitivity and delay settings to adapt to different welding techniques and ambient light conditions

How to use

Before use, inspect the helmet for damage and ensure the viewing window and protective covers are clean. Adjust the shade level and sensitivity according to the welding process and ambient light; consult process guidelines for recommended shade ranges. Fit the helmet securely using the headband adjustments so that the viewing area aligns with the eyes and the shell covers the face. During welding the auto-darkening filter will switch to the selected shade; after welding it will return to the light state to allow inspection of the weld. Replace the backup battery as needed and keep the solar cell exposed to light to maintain charge.

Usage recommendations

Use appropriate personal protective equipment in addition to the helmet, such as gloves, protective clothing and safety footwear. Regularly check and replace worn or damaged filter covers and the backup battery. Select shade and sensitivity settings that match the welding process to ensure both protection and clear visibility.
