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
Description
Passive ALF is the name attributed to the latest safety helmet designed specifically for hand-held laser welding applications.
The Passive ALF is able to be used in a fully safe Laser Interlock® System. The helmet must be worn in the proper position in order to arm the laser. This design encourages users to always be mindful of protection well before any welding takes place.
User safety is paramount and using the Passive ALF Interlocked Helmet will reduce the amount of laser energy transmitted to a safe level in the event that there is either a direct hit or a high level of reflection from the laser welding process.

Interlock® Control
To provide control of the system, you will need an Interlock® Controller – this will depend on the configuration desired.
The three main configuration options are below:
ICS-7-ALF
Interlock® Controller
- Automatic arming
- Multiple interlock inputs
- Monitor doors, switches, overrides, signs, etc.
- Versatile and modular
ICS-SOLO
Interlock® Controller
- Remote arming
- Single interlock input
- Ideal for small enclosures with a single laser
- Low-cost and simple to use
Direct
Direct connection to Laser
- Automatic arming
- No controller required
- Helmet is wired directly to the laser via a distribution box
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
The Laser Castle Lite is a modular interlocked laser enclosure that can be self-assembled by the user. The enclosure keeps workers safe by preventing the escape of laser radiation when in operation.
It comes complete with a manually operated door, safety interlock switches, dual-message LED warning sign, emergency stop break glass, internal emergency stop button, and entry door maglock – all linked to an Interlock® Controller.
The Laser Castle Lite is built from the same laser blocking material as the Laser Castle. For low-cost ventilation, the cabin has an open roof and can be rapidly deployed on site. It is supplied as a low-cost cabin in flat-pack form to enable easy transport and assembly by the customer.
DOLPHIN LASER SAFETY POD
The Dolphin Laser Safety Pod is a curtain enclosure that enables users of handheld laser welding devices to work without endangering surrounding workers from laser radiation.
Lasermet’s Dolphin Laser Safety Curtain pods are made from the company’s latest specially developed Dolphin laser-blocking material. The pod is an 8ft (2.4m) cube and the material is black on both sides.
