Passive ALF Interlocked Laser Welding Helmet

Interlocked Laser Safety Helmet for Hand-held Laser Welding 
Designed specifically to protect welders from stray laser radiation, the interlocked helmet design requires the helmet to be properly worn with the visor closed before firing the laser.
  • Protection from laser radiation
  • Passive laser filter protection
  • Integrate with Laser Safety Interlock® Systems

Passive ALF is the latest safety helmet designed specifically for hand-held laser welding applications

The Passive ALF can be used in a completely safe Laser Interlock® System. To arm the laser, the helmet must be worn in the proper position. This design encourages users to consider safety well before any welding takes place.

The Passive ALF Interlocked Helmet is designed to reduce the amount of laser energy transmitted to a safe level in the event of a direct hit or a high level of reflection from the laser welding process.

Interlock® Control

An Interlock® Controller will be required to provide system control, depending on the configuration desired.

The three main configuration options are below:

Passive ALF with Lights

The passive ALF can be accessorised with lights to have a brighter working station. The lights are factory fitted and is rechargeable using a type-C cord supplied by Lasermet.

The lights have two lighting sources, a wide light for an even spread of the lights within the users view and focus lights to illuminate a specific part of the working material. Aside from the two lighting source, the light can be set up to 5 different light modes depending on how many times the power button is pressed:

1Wide light, max brightness
2Wide light, medium brightness
3Focus light, max brightness
4Focus light, medium brightness
Long press (for 3 secs)Wide light, flashing

Note that the lights are not available as an individual order and is factory fitted with the helmet.

Integration into Laser Enclosures

In addition to integration with Laser Interlock® Systems, the Passive ALF can be fitted to a laser enclosure such as the Laser Castle Lite or the Dolphin Laser Safety Pod.

For best practice, hand-held laser welding set-ups should include a laser welding enclosure, an Interlock® Controller, and the Passive ALF Helmet.

Laser Castle Lite
LASER CASTLE LITE

The Laser Castle Lite is a modular interlocked laser enclosure that the user can self-assemble. When in use, the enclosure protects workers by preventing laser radiation from escaping.
It features a manually operated door, safety interlock switches, a dual-message LED warning sign, an emergency stop break glass, an internal emergency stop button, and an entry door maglock, all of which are linked to an Interlock® Controller.
The Laser Castle Lite is constructed with the same laser-blocking material as the Laser Castle. The cabin has an open roof for low-cost ventilation and can be easily set up on site. It is delivered as a low-cost flat-pack cabin for easy transport and assembly by the customer.

Dolphin Laser Safety Curtain Pod
DOLPHIN LASER SAFETY POD

The Dolphin Laser Safety Pod is a curtain enclosure that allows handheld laser welding device users to work without exposing nearby workers to laser radiation.
The Dolphin Laser Safety Curtain pods from Lasermet are made from the company’s most recent specially developed Dolphin laser-blocking material. The pod is an 8ft (2.4m) cube with black material on both sides.
