UL standard OTA-3000 380V industrial high-power four-in-one handheld fiber laser welding machine, with lifetime warranty

The 380V four-in-one handheld laser welding machine is a multi-functional fiber laser equipment with industrial three-phase power supply, water-cooled cooling system, and is a mainstream power option of 2000W/3000W. It only supports 380V three-phase industrial power supply in factories. It is equipped with an internal constant-temperature circulating water cooling system. This machine integrates four functions: laser welding, metal cutting, laser rust and paint removal, and weld seam polishing and cleaning. It is a fixed-position industrial model, focusing on long-term full-load continuous production and suitable for batch processing of medium-thick plates.

1. Laser welding (main function)

   Equipped with an automatic wire feeder, it supports swing welding, fish-scale welding, and filler wire repair. The 3000W model can achieve a stable welding thickness of 5–8mm for stainless steel, and can process carbon steel, aluminum alloy, galvanized sheet, titanium alloy, and copper materials. The weld seam has a large molten depth, is firm and free from voids, and has a much smaller thermal deformation than argon arc welding. The welding efficiency is 3–6 times that of traditional welding.

2. Laser thin plate cutting

   Change the cutting nozzle and switch modes with one click. It can be assisted by oxygen/nitrogen for cutting. The 3000W carbon steel can be cut to a maximum of 6mm, and stainless steel to 4mm. The cutting edge is smooth without burrs and does not require grinding.

3. Laser cleaning and rust removal

   Non-contact removal of rust, oxide scale, oil stains, old paint, and coatings. No consumables, no damage to the base material. Suitable for batch workpiece pre-treatment and equipment refurbishment.

4. Weld seam polishing and cleaning

   One-click removal of the black oxide layer and welding slag on the weld seam, replacing the angle grinder. The finished weld seam is bright, significantly reducing post-processing procedures.

1. 380V three-phase industrial power supply, with stable high-power output

   The 2000W/3000W high-power models must be driven by 380V power supply. The power supply is sufficient, the power is not overstated, and there is no attenuation during long-term operation; it can be matched with industrial generators, and is highly compatible with large factories and steel structure workshops.

2. Constant temperature water-cooled cooling, capable of continuous production 24 hours a day

   The entire machine integrates a dual-temperature dual-control water-cooling circulation system. The cooling efficiency is much higher than that of 220V air-cooled models. There is no overheating shutdown limit, and it can operate at full load continuously for welding, cleaning, and cutting throughout the day. It is suitable for assembly lines and large-scale processing.

3. Higher processing thickness limit

   The air-cooled 220V model has a limit of 3mm thin plates; the 380V water-cooled 3000W can stably weld 5–8mm medium-thick metals, and has obvious advantages in steel structure, heavy sheet metal, and thick pipe welding.

4. Intelligent industrial control system

   7-inch industrial touch screen, with dozens of pre-set processes for carbon steel, stainless steel, aluminum, copper, etc., and can store multiple sets of parameters; the welding gun has sensing capabilities, automatically cuts off light when the material is away, and has complete protection against accidental operations.

5. One machine for four uses, reducing equipment investment in the factory

   It can simultaneously replace handheld welding machines, plasma cutting machines, and independent laser cleaning machines, saving equipment procurement, floor space, and labor transportation costs.

6. Durable with low attenuation

   Industrial-grade fiber laser, with a large-power redundant design, has slow power attenuation during long-term high-load use, and has a longer service life.

• Carbon steel, stainless steel, aluminum alloy, galvanized sheet, manganese steel, titanium alloy, copper alloy, alloy plates (covering thin plates to medium-thick plates).

• Heavy-duty steel structures, elevator racks, storage shelves, pressure vessels, engineering machinery sheet metal, batch production of doors and windows guardrails, thick material processing for kitchens and bathrooms, automotive sheet metal refurbishment, pipe processing, batch repair of molds, rust removal and refurbishment of large equipment, automated supporting workstations.

• It requires 380V three-phase industrial electricity. Ordinary stores and outdoor areas without three-phase power supply cannot use it.
• The total weight of the machine is 120–270kg. It is relatively large in size and inconvenient to move and transport. It is mainly used for fixed-position operations.
• Water maintenance is required: The circulating water needs to be replaced every 3–6 months. In winter, in low-temperature environments, antifreeze needs to be added to prevent pipeline freezing.
• The power consumption of this machine is higher than that of the 220V air-cooled model. The electricity cost for long-term intermittent small-scale processing is higher.
