A. Solar-powered photovoltaic technology is now quite mature in the welding sector, and is widely used across most brands of auto-darkening filter ADF welding helmet. All ADF welding helmets have a battery of some kind, but those not marketed as battery-powered or battery-assisted tend to be categorised as solar-powered and depend on a low-voltage rechargeable cell, which is topped-up by the photovoltaic panel to provide an acceptable service life. Weldability Phantom XL, is battery-assisted and includes a lithium coin or similar cell to increase the voltage and therefore improve the performance of the ADF. Performance improvement in battery-assisted models is evident through greater sensitivity lower minimum current reactivity, faster switching speed and better reliability. However, this improved technology and performance tends to mean the ADF helmet is at a slightly higher weight and cost.
