Fiber Laser Welding Helmet Gen2

The best value laser welding helmet on the market, meeting the stringent EN207 laser eyewear standard up to 3kW with our hand held laser welders.

Its special multi stage infrared and UV filter with variable auto dimming is unmatched on the market, along with its shielding.

Gen2’s filter and shield are not damaged by multiple laser strikes, where other far more expensive helmets may require replacement after only one high intensity laser strike.

Certified for both arc welding AND laser welding, so you only need one helmet for all your welding.

Scope of protection from fiber laser radiation

Our laser welding Helmet Mk2 has been designed and developed to keep your eyes and face safe from strong laser reflections from fibre laser welders up to 2kW or even 3kW. This has been tested for the YAG and fibre laser wavelength range of 1060 to 1085nm.
It passes the “worst case” penetration test of EN207 for “Laser Welder” brand hand held laser welders from laser-welder.net or laser-welder.com.au based on a total divergence angle of 0.75 degrees (based on a circle which contains 63% of the laser power), and 100% specular reflection at 100% power on a 2kW laser welder held 41cm or 16 inches from the nozzle/tip.
Protection is provided for at least 5 seconds of continuous exposure at this condition, but stop welding and/or move out of the way immediately if a laser strike is suspected.
Fibre laser glasses sold by laser-welder.net or laser-welder.com.au must be worn under this helmet.  This provides redundancy and protection in the case of a user forgetting to flip their helmet down for example.
This helmet protects the user from Infra Red (IR) and Ultra Violet (UV) radiation when used per these instructions.
The auto darkening feature automatically changes from light to dark when welding is detected, then turns light again when welding is completed. This protects the eyes from extreme brightness caused by welding.

Multiple layers of protection

Multi layered defense system meets EN207 and OSHA requirements for laser welding:
Filter 0: Clear, protective clear plastic covers inside and out to keep out spatter, grind particles, etc.
Filter 1: Special infrared blocking “clear” filter for 700-1100nm IR.
Filter 2: Silvered multi layer filter for UV and IR
Filter 3: Auto LCD filter for visible light, adjustable for comfort
Shell 1: Frame: Reflective heat shield
Shell 2: Reflective coating
Shell 3: High temperature polymer

Arc welding use in addition to laser welding

Certified for arc welding in the USA and also where EN379 applies:
Meets ANSI Z87.1
Meets CE EN 379

Laser cleaning can be extremely bright, even brighter than laser welding. Hence variable shade with auto dimming is strongly recommended.  Variable shading is featured as standard fitment on this helmet.

Federal standard 29 CFR 1926.102(b)(2), for eye and face protection, states that “employees whose occupation or assignment requires exposure to laser beams shall be furnished suitable laser safety goggles which will protect for the specific wavelength of the laser and be of optical density (O.D.) adequate for the energy involved.”  For more information see https://www.osha.gov/otm/section-3-health-hazards/chapter-6

Based on our testing, we strongly believe the required OD rating 8 of ANSI is NOT enough in isolation.  OSHA’s regulation, to their credit, allows superior standards such as EN207.

Our in-house testing showed class-leading protection on the EN207 laser penetration test at 2kW.  ANSI doesn’t test for penetration, but we’ve heard several reports of regular helmets melting due to reflections, and the risk of facial burns, so we think it’s very important.  Our shell is a high temperature polmer, reflective white, with external shielding which far exceeds most if not all competitors.
