HELMET/LENS INFORMATION
The Auto-Darkening Lens in this welding helmet will
automatically change from light state (Shade 3.5) to dark state
(5-13) when arc is initiated.
The lens automatically returns to a light state when the arc
stops.
Before welding, match your welding application to the shade
indicated on the shade guide setting chart. (See Page 20) Also
adjust the sensitivity setting to your welding
application/environment.
This Auto-Darkening Welding Helmet is designed for use with
GMAW, GTAW, SMAW welding, or Plasma Arc and air carbon arc
cutting.
The Auto-Darkening Lens provides protection from harmful UV
and IR radiation, in both dark and light states. No matter what
shade the lens is set to, the UV/IR protection is always present.
The Auto-Darkening Lens contains four sensors to detect the
light from the welding arc, resulting in the lens darkening to a
selected welding shade.
• Do not use solvents or abrasive cleaning detergent.
• Keep the sensors and solar cell clean.
• If cover lens is spattered or covered with dirt, it should be
replaced immediately.
• Use only replacement parts specified in this manual.
• Do not use the helmet without inside and outside cover lenses
properly installed.
• Do not use the auto-darkening lens if damaged by shock,
vibration or pressure.
