Professional-level OTM-1500 1500W heavy-duty three-in-one industrial handheld fiber laser welding machine, with lifetime warranty

The "Sanhe" model with a laser welding machine is a basic multi-functional fiber laser all-in-one machine. It integrates three core functions: laser welding, laser cutting, and laser rust removal and cleaning. It does not have additional functions such as weld seam polishing or precise pulse welding. It is available in two versions: a 220V air-cooled portable model and a 380V water-cooled industrial model. The mainstream power ratings are 1000W/1500W/2000W/3000W. It comes with a swinging handheld welding gun, an automatic wire feeder, and a 7-inch touch screen. It is an entry-level model with good cost performance for the hardware, doors and windows, advertising, and retail industries.

1. Laser welding (core main function)

   It can complete fish-scale welding, butt welding, corner welding, lap welding, and gap filling welding repair by combining with wire feeding machines;

   The air-cooled model can stabilize welding of 0.3–3mm thin plates, while the water-cooled model with 3000W can weld 5–8mm medium-thick plates;

   The heat affected zone is small, and the workpiece is less likely to deform. The welding efficiency is 3–5 times that of argon arc welding, the weld seam is smooth, and the grinding process is reduced.

   It is compatible with conventional metals such as stainless steel, carbon steel, galvanized sheet, aluminum alloy, and titanium alloy.

2. Thin plate laser cutting

   By replacing the special cutting nozzle and switching the system parameters, it can be used as an auxiliary processing function;

   The maximum cutting thickness with air cooling is 3mm for carbon steel, and with water cooling it can cut 5–6mm for carbon steel. The cutting edge is smooth without slag residue, and it replaces small plasma cutting machines.

3. Laser rust removal and cleaning

   It can remove iron rust, oxide scale, oil stains, old paint, and coatings without contact with the workpiece, without consumables, and without damaging the base material;

   It is mainly used for pre-treatment before welding, equipment renovation, and rust removal of old components, and is environmentally friendly with no dust pollution.

• 220V air-cooled three-in-one (portable model)

  - Power supply: 220V single-phase for household use, applicable for stores, construction sites, outdoor on-site installation

  - Cooling: The entire machine has an internal ventilation duct fan. There is no water passage and no need for antifreeze. Only regular cleaning of the filter is required

  - Weight: 28–40kg, with swivel wheels and carrying handle, allowing for easy transportation by one person

  - Limitations: Intermittent operation. After full welding for 10–15 minutes, the machine needs to be stopped for cooling. It is only suitable for thin plates up to 3mm in thickness.

• 380V water-cooled three-in-one (industrial fixed model)

  - Power Supply: Three-phase 380V industrial electricity for the factory, with high power output that is stable and continuous

  - Cooling: Dual temperature dual control circulating water system, capable of supporting 24-hour uninterrupted full-load production

  - Weight: 110–150kg. Suitable for short-distance movement within the workshop and for fixed positions in batches

  - Advantages: Stronger molten depth for thick plates, no overheating shutdown during long-term processing, suitable for batch processing of medium-thick plates

1. One machine for three purposes, with lower cost

   This single device replaces independent welding machines, small cutting machines, and rust removal machines, reducing procurement and factory space investment. Compared to four-in-one and five-in-one models, its price is more affordable.

2. Simple and easy to operate

   The touch screen is equipped with pre-set processes for carbon steel, stainless steel, and aluminum alloy. By changing the nozzle, the functions can be switched. With no prior knowledge, simple training is sufficient for operation.

3. Flexible and versatile

   The air-cooled model can be installed on-site and repaired at heights; the water-cooled model is suitable for small and medium-sized sheet metal and steel structure factories, covering processing from thin plates to medium-thick plates.

4. Simple maintenance

   The air-cooled model has no waterway maintenance; for the water-cooled model, only
