KELTIN auto-darkening welding mask

The auto-darkening welding mask is designed to protect the eyes and face during welding from sparks, spatter and harmful UV and IR radiation.

The mask is suitable for welding by all electric-arc methods - covered electrode (MMA) and semi-automatic in gas shield (MIG-MAG) and TIG. Additionally, welding by the TIG method (-) at low current (20A) is also possible.

The filter cassette contains two photosensors that react to welding arc light; they automatically detect the start of welding and activate the auto-darkening function. After finishing work the filter automatically returns to the light state.

The auto-darkening filter has two independent power sources:

• built-in battery powered by solar cells
• two external AAA batteries

Adjustable parameters and mask size allow the product to be properly adapted to the type of work and the user's expectations.
