Professional-grade OTA-3000 380V heavy-duty four-in-one industrial handheld fiber laser welding machine, equipped with Hanli cooler

The 2000W four-in-one model is divided into a wind-cooled portable version (220V single-phase) and a water-cooled industrial version (380V three-phase). The entire machine integrates four functions: welding, metal cutting, laser rust and paint removal, and weld oxidation cleaning. It is a mainstream model that combines power, multiple functions, and versatility, suitable for store processing, outdoor construction, and batch production in small and medium-sized factories.

I. Overall Overview of the Equipment

II. Four Core Functions

1. Laser Welding (Core)

   Air-cooled: Stainless steel 0.3–3mm, carbon steel 0.3–4mm, aluminum alloy 0.3–2.5mm;

   Water-cooled: Stainless steel 0.3–5mm, carbon steel 0.3–6mm, aluminum alloy 0.3–4mm;

   Supports fish-scale welding, lap welding, corner welding, and filler wire repair. The thermal deformation is minimal, and the welding efficiency is 3–5 times that of argon arc welding. The weld seam is smooth and requires minimal polishing.

2. Thin Plate Cutting

   Change the cutting nozzle and switch modes with one click. Air-cooled can cut up to 3mm carbon steel, water-cooled can cut 5mm carbon steel. The cut edge is smooth without burrs, replacing plasma cutting machines.

3. Laser Rust Removal and Cleaning

   Non-contact removal of rust, oxide scale, oil stains, old paint, and coatings. No consumables are used and the base material is not damaged. Equipment refurbishment and pre-treatment of workpieces are efficient and environmentally friendly.

4. Weld Seam Polishing and Cleaning

   One-click removal of black oxide layer and welding slag on the weld seam. No need for angle grinder polishing. The finished weld seam is bright and tidy.

III. Core Advantages of the 2000W Portable Air-Cooled Model

• Flexible movement, no waterway maintenance required

  No waterway, no freezing, no leakage. Can be used in outdoor low-temperature environments, only need to clean the heat dissipation filter screen regularly; plug in 220V power supply and use immediately, no need for preheating and waiting.

• Compact size, single-person handling

  The entire machine is lightweight, can be moved at any time in construction sites, high places, or for door-to-door maintenance, not limited to fixed workstations.

• Energy-saving and low noise

  The power consumption of the entire machine is much lower than that of water-cooled type, saving electricity during long-term intermittent processing in stores.

• Multi-purpose in one machine

  One device can replace welding machines, cutting machines, and rust removal machines, reducing equipment procurement and floor space costs.

Air-cooling drawback: Limited heat dissipation. Full welding requires intermittent cooling for 10-15 minutes. It is not suitable for 24-hour continuous production lines. The continuous processing capacity for thick plates is weaker than that of water cooling.

IV. Core Advantages of the 2000W Water-Cooled Industrial Model

• Constant temperature water cooling, continuous operation throughout the day

  The water circulation for heat dissipation is stable, without overheating shutdowns. It is suitable for small and medium-sized factories for continuous batch processing.

• Stable power output

  380V three-phase power supply, sufficient weld penetration for thick plates, and more stable welding formation for aluminum alloys and thick carbon steel.

• Durable and low attenuation

  Industrial-grade laser, slow power attenuation under long-term high-load conditions, longer equipment lifespan.

Water cooling drawback: Requires three-phase industrial power supply. The entire machine is bulky and inconvenient to take with you; the circulating water needs to be replaced every 3-6 months, and antifreeze needs to be added in winter to prevent freezing and cracking.

V. Applicable Processing Materials

Carbon steel, stainless steel, galvanized sheet, aluminum alloy, titanium alloy, thin copper parts, manganese steel and other common metal sheets.

VI. Applicable Industry Scenarios

• Air-cooled model: Advertising illuminated signs, installation of stainless steel/aluminum window guard doors, hardware stores for kitchens and bathrooms, on-site repair of molds, small-scale sheet metal sporadic processing, outdoor steel structure maintenance.
• Water-cooled model: Small and medium-sized steel structure factories, elevator bridge frames, storage shelves, batch processing of automotive sheet metal, thick material kitchen and bathroom processing, batch rust removal and refurbishment of equipment.
