Brand new and high quality.
<br />1)  VARIABLE SHADE CONTROL ¨C The Shade can be adjusted from shade 9 to 13 based upon the Welding Process or Application (refer to Shade Chart) The variable shade control knob is mounted on the outside of the Helmet Shell
<br />2)  SENSITIVITY KNOB ¨C You can adjust the light sensor by turning the Sensitivity Knob. Generally turning the knob to the highest sensitivity setting is the best choice for normal use, but when the Helmet is used in the presence of excess ambient light or with another welding machine close by, improved helmet performance can be obtained with a lower setting.
<br />3)  DELAY TIME KNOB ¨C This control is designed to protect the Welder¡¯s Eyes from the strong residual rays after welding.  Changing the Delay Time will vary dark to light time between 0.1 second (minimum) to 1.2 second (maximum). The maximum setting is recommended for high amperage applications where the Weld Puddle is still very bright after the welding arc has ceased and for situations where the filter may be temporarily blocked from seeing the welding arc.
<br />4)  When arc is struck,Auto- darkening Filter will turn from clear state to dark state,response time is less than 1/10,000S.
<br />5)  Auto-Darkening welding Helmets are designed to protect the eyes and faces from spark, spatter, and harmful radiation under normal welding conditions.
<br />6)  Lithium Battery Powered with Solar Backup.
<br />7)  Ample mask space and very safe structure.
<br />8)  Suitable for high welding operation temperature.
<br />9)  Welding or Grinding Selection.
<br />10)  Outside shade number and sensitivity adjustable can make the operators more convenient while operating.
<br />11)  Large view window dimension for observation easily.
<br />12)  Right and left hander can select the suitable stile.
<br />13)  Auto darkening lens will automatically darkens to it's selected shade number when the light from welder is detected.
