Here are some common terms and definitions to help you decide which features you want in an auto darkening welding helmet:
Delay Adjustment: allows user to adjust the amount of time before the lens transitions back to light stateSensitivity Adjustment: allows user to fine tune unit depending on ambient light or arc intensity; allows low amp, DC TIG welding other units cannot do
Solar Battery Life Extender: extends welding hours; solar cell increases economical operation-decreases battery replacement cost and downtime
Intellisense: allows unit to detect welds less than 5 amps
3N1: 3 modes of operation grind (clear state), weld (shade 8.5-12.5) and oxyfuel gas cutting (shade 5); one hood for every welding process.
HTLS Lightstate: shade 3.75 clear state, the clearest PI filter available; allows good color and visibility for hood down set up in low ambient light settings
Independent Redundant Sensors: if one sensor is blocked or damaged, the unit’s performance will not be damaged; enables welder to work in tight areas.
Auto Off: manually shut down unit when not in use, or automatic shut-off after 20 minutes non-use; maximizes battery life.
ClimaSensor Technology: tests the ambient air temperature three times per minute and automatically adjusts to ensure true shade when welding
EMI Coating: special coating designed to shield and protect electronics against extreme electromagnetic interference.
