This solar powered auto darkening welding helmet works without batteries. It avoids welding spatters. The extreme temperatures won’t affect the welders; when welding, in summer it won’t be hot and the mist in the lenses won’t appear in winter. Suitable for use at high welding operation temperatures. The headband strap is adjustable and provides a comfortable and non-slip fitting, meanwhile wearers have both hands free for their work. It has contoured frame edges to deflect particles and splashes. It can be used easily without feeling its heaviness. Black coloured.
