introduction and advantage

Good Material and Durability Features

The higher quality materials been used to construct the welding helmet, making it more durable, able to withstand harsh work environments, and provide a longer lifespan and this welding helmet is in full conformity with related ANSI, CE, CSA, AS/NZS safety standards to provide better protection for welders.

Good Optical properties and better protection and using experience 

The auto darkening filter of this welding helmet using the good 2nd generation true color ADF technology combine with our excellent electronic advantage, it brings welders more clearer view, reduced dizziness, reduced eye fatigue and better protection. Good optical performance can help welding personnel perform welding operations more accurately, reduce the need for inspection and correction, and reduce eye fatigue, thereby improving work efficiency and comfort.

Good for Tig welding

Our auto darkening filter provides competitive edge in low current TIG welding compared to others’ products on the market by offering the ability to perform TIG welding at 2A without any flickering or distractions. With advanced technology, our auto darkening filter increase visibility, reduce glare and improve clarity, allowing welders to perform TIG welding operations with greater precision and comfort. Our welding helmets stand out for their superior optical properties, ensuring welders can work more efficiently and with less eye fatigue.
