FDA Registered OTA-2000 110V 60Hz Air Cooled Handheld Fiber Laser Welder for

2000W Four-in-One 
- Carbon steel/Stainless steel: 0.8 - 8mm (full power)
- Aluminum: ≤ 6mm
- Copper: ≤ 4mm
- Cooling: Industrial dual-temperature water cooling, capable of continuous production 24 hours a day
- Power consumption: Approximately 8kW
- Advantages: Thicker plates are more stable, aluminum and copper are better, continuous operation without downtime 
Tungsten Inert Gas Welding (TIG) 
- Carbon steel / stainless steel: 0.5 – 20mm +
- Aluminum / copper: Thick plates are more stable, but difficult to weld, prone to deformation and slow in speed
- Cooling: Both air cooling and water cooling are available, but continuous welding is prone to overheating 
 

II. Efficiency Comparison (Directly Affects Production Capacity) 
- 1500W laser: 4-6 times faster than argon arc welding
- 2000W laser: 5-10 times faster than argon arc welding; 20-30% faster than 1500W
- Argon arc welding: 1 meter of stainless steel weld ≈ 12 minutes of welding + 20 minutes of grinding
- 2000W laser: same 1 meter ≈ 3 minutes of welding + 2 minutes of cleaning, saving 80% of working hours 
One 2000W laser ≈ 3 - 4 skilled argon arc welders 
 

III. Weld Quality and Subsequent Processing 
2000W Laser 
- The heat-affected zone is extremely small, and the deformation is almost imperceptible.
- The weld seam is smooth and shiny, without any blackening or excessive spatter.
- The four-in-one system comes with a built-in weld cleaning function, directly producing a silvery-white smooth surface, eliminating the need for grinding or polishing.
- The porosity rate is less than 0.5%, and rework is extremely rare. 
1500W laser 
- Thin plates (≤ 3mm) have an effect similar to 2000W
- Above 4mm, they are prone to melting and not transparent, and have poor stability
- Aluminum/copper welding is difficult and prone to reflection and sparking from the torch 
Argon arc welding 
- The weld lines are blackened, yellowed, with welding slag and significant deformation.
- They need to be ground, polished and corrected, which incurs high labor costs.
- The porosity rate is 5–8%, and rework is frequent. 
 

IV. Operational Difficulty (The Key Factor Contributing to Recruitment Challenges) 
- 2000W laser: Beginners can master it in just 15 minutes, no welder's license required
- 1500W laser: Same as above, simple
- Argon arc welding: It takes 1-2 years to develop the skills, and a license is necessary. Young people are reluctant to do it. 
 

V. Applicable Scenarios (Help You Find the Right Fit) 
Select 1500W: 
- Mainly thin plates (0.5 – 4mm)
- Occasionally used, non-continuous production
- Budget is tight, for stainless steel doors and windows, small sheet metal work, and advertising signs 
Select 2000W (recommended): 
- Medium-thick plates (4–8mm), with aluminum/copper components
- Mass production in the factory, 24-hour continuous operation
- High appearance requirements (for kitchens, bathrooms, new energy, automotive parts)
- Aim for a one-time solution, long-term use, and low rework rate 
Select Argon Arc Welding: 
- Plates over 10mm thick and for heavy-duty structures
- Extremely special materials, with no power supply on site or extremely low budget 
 

VI. Summary in One Sentence 
- 1500W: Sufficient power, affordable price, good for thin plates, weak for thick plates, cannot be used continuously
- 2000W: Industrial gold standard power, suitable for both thick and thin materials, strong for aluminum and copper, stable for 24 hours, no need for grinding, highest efficiency
- Argon arc welding: Slow, tiring, expensive, large deformation, requires skilled operators
