1500 watt laser welding machine safety features

ST-FW1500H/2000H/3000H is a Class IV laser system and routine precautions are required for the safe operation of the equipment.

Built-in features include:

● Key switch control of laser source and Emergency-stop button ensure deliberate operation.

● Fiber laser interlock verifies integrity of laser delivery to the welding gun.

● Laser weld gun trigger, enable and then fire, for intentional operation.

● Part contact electrical interlock turns off the laser power if the welding head is not in contact with the welded parts.

Operators must wear all recommended personal protective equipment (PPE), including laser safety glasses, laser and heat resistant gloves, hats, leather aprons, etc., and other laser and heat resistant clothing.

Available options

● Metal cutting function

Simple cutting can be done, welding and cutting can be switched freely, just change the welding copper nozzle to cutting copper nozzle, very convenient.

● Surface cleaning function

By replacing the laser nozzle and cleaning lens, the material surface cleaning function can be realized to effectively remove rust spots, oxidation layer, oil stains, etc. from the material surface without damaging the surface characteristics.
