Features of 1500w laser welding machine

1. The self-developed handheld welding head has a variety of safety alarm devices for more flexible and convenient operation, overcoming the limitations of the table travel space and meeting the welding of various angles and positions.

2. Adopt infrared positioning for welding position calibration and position verification in the welding process. The welding position is more accurate and the weld seam is more beautiful.

3. Equipped with 10m imported optical fiber, flexible and convenient for outdoor welding and long-distance welding.

4. Smooth and beautiful welding, no deformation, no need for secondary grinding, solving the problems of weld penetration, weld tumor, welding quality, etc. that occur when using argon arc welding.

5. Equipped with high-precision touch capacitive screen wire feeder, 220V drive, automatic wire feed, more powerful wire feed, no wire jamming phenomenon.

6. Suntop's patented technology water circulation protection system and auxiliary gas detection effectively extends the life of the laser lens and prevents damage to optical components caused by Improper operation.

Details of 1500w laser welding machine

Advantages of 1500w laser welding machine

1. Ergonomic design, more reasonable structure, dustproof, good heat dissipation, effectively extending the service life of machine parts.

2. The weld seam is flat, beautiful, without porosity, which can reduce and optimize the base material magazine, the organization can be refined after welding, and the strength and toughness of the weld seam are at least equal to or even exceed the base metal.

3. Fast welding speed, 5-10 times faster than traditional argon arc welding, processing costs can be reduced by about 30%.

4. Interactive human-machine interface, easy to operate, no need for professional welders, ordinary people can easily master in half an hour.

5. High anti-reverse capability, high efficiency for thin plate welding, no spatter for thick plate deep melting, maintenance-free, wide range of operation and frequency regulation.

6. Various welding methods, can achieve any angle welding, stack welding, butt welding, vertical welding, flat angle welding, internal angle welding, external angle welding, etc., can be welded to a variety of complex welding seams of the workpiece, larger workpiece non-regular shape.

1500w 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.
