• Internal sensitivity potentiometer : Sensitivity adjustable according to :
- Light ambient: Without welding, turn the sensitivity setting towards «max», then turn the sensitivity setting towards «low» until filter lightens.
- Welding process: «Max» position for low amperage TIG rpocess / Medium range for most application.
• Internal delay potentionmeter: Controls the delay for the helmet to switch back to clear after welding.
Delay is designed for slower switching time to clear state to eliminate remained bright rays.
• External potentiometer welding:
