Sherman V1a Welding helmet

WELDING HELMET SHERMAN PROFI V1a

| Brand: Sherman | Filter class: 1/2/1/1 | Shade range:  DIN 4 - 13 | Number of sensors: 2 | Field of view: 95x36mm | Grinding: YES |

The automatic welding helmet Sherman-profi V1a is designed to protect the eyes and face against sparks, spatter and harmful radiation during welding and grinding.

The automatic darkening filter automatically changes from light to dark after the arc strikes, and becomes light again after welding.

The use of the full color reproduction TRUE COLOR technology ensures high comfort of work.

The helmet has two external knobs to adjust the shade level from 9 to 13 according to DIN and smooth adjustment of the sensitivity of the photosensors reaction to the arc intensity during welding.

There are two switches on the internal control panel that allow for a three-position adjustment of the delay time for switching the dark / light state and for changing the operating mode . The blackout filter is equipped with two photosensors .

Attention! The helmet is not recommended for welding with low currents of 20-30A.

After selecting the grinding function on the internal control panel, the darkening filter switches to the bright state without the option of adjusting the shade.
