What does E2 alarm suggest in handheld laser welding machine rack mount chiller?

A Bulgarian handheld laser welding machine user had a rack mount water chiller and recently his chiller triggered E2 alarm. So what does E2 alarm suggest? Well, E2 alarm suggests the water temperature of the laser process chiller is too high. There are a few reasons and solutions for this kind of alarm.

1.If the alarm occurs to the newly bought rack mount water chiller, that could be because the chiller doesn’t have sufficient cooling capacity. In this case, change for a bigger one;
2.If the alarm occurs to the chiller which has been used for a certain period of time, that could be because there is serious dust problem in the dust gauze and the condenser. It is suggested to remove the dust in time;
3.The room temperature is too high. In this case, keep the laser process chiller in the room whose temperature is below 40 degree Celsius.

The market of handheld laser welding machine is expected to grow in the coming years

Laser welding application becomes very heated with fast growing rate

Back to 7 to 8 years ago, quite a few industrial experts believed that laser welding was a crucial growing point. With the development of high-end manufacturing, laser welding and precision welding are gradually used in different industries, including smart phones, computers, tablets, portable earphones, hardware, construction used metals and so on. And in the recent 3 years in particular, laser welding becomes quite heated because of increasing need of power battery used in electric vehicles. 

The wide application of laser cutting is the result of mature laser technology and increasing power and laser cutting is gradually replacing traditional processing methods like punch press, water jet and so on. It is a common and preliminary processing. Laser welding, however, is the result of new application of the laser technology. This often comes with upgrading and more complicated, customized technique with higher added value. With this trend, the market value of laser welding will overwhelm the one of laser cutting in the coming future. 

Handheld laser welding machine becomes a poplar welding device in the laser welding market

A new application and the diversity of the application will provide unpredictable potential for laser welding. How big is the laser welding market? For the time being, domestic laser welding market is thriving in all aspects. And there is one aspect that needs to mention -- the compact handheld laser welding machine becomes a popular welding device in the laser welding market.
