For welders who need basic protection in an autodarkening helmet and perform overhead welding, the optrel e640’s ergonomically curved helmet shell deflects smoke, particulate, and other debris.
Sensor Slide – optrel’s patented Sensor Slide allows the detection angle to be reduced from 120° to 60°, preventing the ADF from responding to nearby welders’ arcs.
Overhead Welding – The optrel expert line’s curved helmet design deflects smoke, particles, and other debris when performing overhead welding.
