Should we choose air cooling or water cooling for butt welding machine?

Butt welding machines are divided according to usage scenarios: air-cooling and water-cooling depend on the calorific value. Those with low frequency of use can be air-cooled, and those with high frequency of use can choose water cooling. Butt welding machines are divided according to power: generally, those below 25KVA are air-cooled, while 25-50KVA can be air-cooled or water-cooled. Above 50KVA generally require water cooling.

The difference between the old gear butt welding machine and the new CNC butt welding machine - NOVEL WELDER Welding

The old-style butt welding machine generally has adjustable power of 50-100% in gears 1-8. The new CNC butt welding machine has 99 gears from 1-100%. The best adjustable range is controlled at 20-90%. The adjustable range is larger and the applicable range is wider! Old customers can choose older butt welding machines due to their usage habits, while new customers and those who want to increase the number of welding machines can

The role of insulated safety handrails for butt welding machines-NOVEL WELDER Welding

The electrical safety of butt welding machine equipment has always been a focus of everyone's attention. The welding machine must comply with the national GB15578 safety standard. The insulation value of the butt welding machine can generally reach more than 3.5M ohms, and the grounding is good. However, there are occasional electrical accidents every year. For this reason, Xinxing specially installed safety insulated handrails for the new butt welding machine.
