Generally, there is a device introduction on the back of the
Laser Welding Machine body, from which you can get the power size of the device, other accessories information and safety maintenance knowledge.
How to choose a device suitable for power? This depends on your requirements for the depth of the Water-cooled
Handheld Laser Welder. For example, 30W can hit the depth, 20W is not enough, 20W can hit the depth, 30W device can produce the same effect by reducing the power to 20W, and actually adjust to the highest power when using it.
You can use the credit card test method, buy several metal credit cards, adjust the power from 10, 15, 20, to the highest, and then drive the car on the credit card.
Observe and touch it with your hands, and choose the one with the best effect, which is the best power. If you can't get the required depth even if you adjust it to the highest, then you can only buy a device with a higher power.
