Notify users in noisy environments of low battery due to reduced airflow.
Four independent arc sensors provide superior lens response for obstructed or low amp welding.
For ease of switching between two preset customized memory settings
Tracks how many hours of use the filter has.
Monitors arc time and arc count for quoting and metrics
Enhances peripheral vision, amplifying sense of surroundings.
Enhances wear without causing skin irritation. Unique design can provide additional protection by covering the ears, or ease communication if placed in front of the ears.
Provides long battery life (up to eight hours) with no memory retention from frequent charging (three-hour charge cycle). Rated for 500 charges. Two batteries are included with each system.
Provides fine shade adjustment for optimized comfort and vision.
Provide 20 hours of run time, decreasing down time
Patent-pending Dualtec manifold design with 6-point airflow distribution system maximizes perceived cooling through targeted air placement. This system targets the body’s natural thermal regulation system to minimize operator heat stress. Its six-point airflow distribution system targets “hot” areas within the face for immediate cooling relief, without causing eye and/or nose irritation.
