1. Environmental Protection and Energy Saving
Since Welding has become one of the most prominent manufacturing processes, the major botherable concern is the high amount of yearly resource consumption for providing power for welding.
ComWelder has incorporated high-performance chips into their welding processes, significantly reducing the heat input required for operation. This innovative approach minimizes the secondary energy consumption caused by heat dissipation.
Another compelling element of the B1 laser welder is the in-built air cooling system that helps maintain the optimal performance and longevity of the laser source.
The air cooling technology in ComWelder B1 uses components like inverter fans that, on one side, provide cooling to the radiator and simultaneously cut down more than 65% on the power consumption.
This aims to enhance air convection and complete heat exchange inside the machine. When the laser is operating, the inverter fan rapidly rotates, blowing air into the radiator and dissipating the heat through convection and radiation.
This cooling method is simple and effective and is a game changer.
2. Compact Design For Modern Needs
The components of the ComWelder B1 laser welding machine are well accumulated in a compact portable unit, largely minimizing floor space usage. From delicate, detailed welding to secure joints, this desktop Compact laser can be used across all areas of application.
The compact design, small footprint, and movable pulleys allow the working condition of the ComWelder B1 laser machine to be more flexible and precise.
This portable fiber laser device is way more accessible than ever. Like TIG and MIG welding operators, the facilitator uses a “gun” to trigger and direct the laser beam. This makes the machine highly convenient so that even novice, inexperienced, or new welders can get a hold of it, and they can be productive and create high-quality welds, as the learning curve is much lower.
The lightweight machine, measuring 38kg in total, perfectly suits the situation when taking the machine into tight or constricted spaces. It can be transported easily from one job site to another, giving it a competitive advantage over stationary welding systems. This becomes a viable machine for welders who travel to different workstations.
Apart from being power-efficient and cost-effective, this small-size ComWelder B1 welder allows easy maneuverability, especially if you’ll be working on complex or large-scale projects. The comfortable grips and adjustable controls enhance user experience and reduce fatigue during prolonged welding tasks.
3. Quiet Operation, Creating a Quiet Working Environment
The laser adopts water-cooled heat dissipation, offering many advantages such as high electro-optical conversion efficiency, low energy consumption, compact structure, adjustment-free maintenance, and easy customer integration.
The fantastic feature of the ComWelder B1 welding machine is inverter technology variable-speed fans. These fans are a real game changer that adjusts the speed based on the actual cooling needs of the welding machine.
When light-duty welding is operating, or the machine is in the standby position, these fans run at a lower speed, which produces less noise.
When the welding machine operates under heavy loads and generates more heat, the fans can increase their speed to maintain proper cooling. This dynamic fan speed control helps minimize unnecessary noise.
4. Humanized Maintenance
ComWelder B1 laser welder features a removable welding head with manual controls to allow you to modify the laser diameter and power output in real-time. This ability will facilitate adjusting the laser depending on precise needs, resulting in a welding head well-suited for in-field metal repairs where space and time are constrained.
The primary applications of this welding head are to do in-field welding and brazing of damaged specialized equipment. The laser technology is a variable-power, continuous-wave, handheld fiber laser head for fusing metals with increased precision and maneuverability.

- Stable and Reliable Performance
Lasers’ ability to focus at a micro level makes them phenomenal. Laser welding can target a spot as small as 0.2 mm.
The ComWelder B1, targeting a 1070±10nm wavelength, is shorter than CO2 lasers. This means that this welder has enhanced laser absorption that can lead to deeper weld penetration, especially in reflective materials like aluminum and mild steel.
Moreover, fiber laser welders have better beam quality than YAG lasers. Fiber laser welding combines the benefits of CO2 and YAG lasers and gives better performance.
Material thickness is also not an issue, as laser welding can easily create deep keyhole penetration for clean welding seams. Moreover, fiber lasers can achieve a welding speed of 16 mm/s (and higher) with ease which was difficult in the past.
7. Advanced Swing Function
The in-built oscillation (the side-to-side rapid movement of the electrode in a dot, straight mode) mechanism in ComWelder B1 weaves the welding arc through the Left / Right direction as an oscillatory movement over the weld surface.
The B1 Welding oscillators control the laser head with the back-and-forth movement to reduce the number and layers of the weld by controlling oscillating speed, width, and pause time. Then, minimize welding defects for perfect welding seam.
This B1 welder will do the trick for you if you’re looking for better and more accurate work.
This highly regulated oscillatory movement of an arc ensures the controlled spread of Arc Heat over the weld surface, resulting in a uniform, smooth, precise, and stable flow of weld globules.
The Controlled & and regulated spread of Arc heat provides a distinctive advantage of excellent penetration at maximum Heat Utility efficiency. This also ensures reduction in the Affected Zone, High welded metal deposit efficiency and highly uniform fused beads.
Since the advanced swing function controls the heat input, the spatter from the weld is significantly reduced.
This means you’re at peace of mind from worrying about too much spatter on the surface. This also reduces the chances of chemical reactions that can cause danger to the welder.
