Integrated Hard Hat Protection

This model includes a removable ANSI Z89.1 Type 1 Class C hard hat designed for industrial environments where overhead protection is required. The removable system allows flexible use between shop and construction applications.

---

Respiratory Protection System

Compatible with the Optrel e3000X NIOSH-approved PAPR system, the Helix Pure Air 2.5 continuously circulates clean filtered air inside the helmet to reduce exposure to welding fumes, smoke, aerosols, and airborne particles.

---

Light State 2.5

The ultra-bright 2.5 light state provides exceptional visibility between welds, reducing the need to constantly lift the helmet and improving productivity.

---

Panoramic XXL Field of View

The panoramic viewing system provides up to 6.3 times the viewing area of standard welding helmets, improving peripheral awareness and weld positioning accuracy.

---

Slide-Up Welding & Grinding System

The integrated slide-up lens allows seamless transitions between welding and grinding without removing the helmet.

---

ShadeTronic® Auto-Darkening Technology

ShadeTronic automatically adjusts the shade level based on welding arc intensity to maintain consistent eye protection during changing welding conditions.

---

True-Color Optics

The true-color lens technology delivers realistic, high-contrast color visibility with reduced green tint for improved puddle visibility and weld precision.

---

FadeTronic® Eye Comfort

FadeTronic technology allows the lens to gradually return to light state after welding to reduce eye strain during extended work periods.

---

Multi-Sensor Arc Detection

Five integrated arc sensors provide reliable activation even during low-amp TIG welding and difficult welding positions.

---

IsoFit® Adjustable Headgear

The fully adjustable 3D IsoFit headgear system evenly distributes weight for improved comfort and reduced neck fatigue during long shifts.
