How to equip the CNC plasma cutting machine with a suitable plasma power supply 
CNC plasma cutters are used in a wider range of applications than flame cutting, especially for stainless steel and non-ferrous metals that are not available in flame cutting. When consulting CNC plasma cutters, many customers often ask about plasma power supplies. CNC CUTTER LIMITED / MEISARCNC as a professional agent to produce CNC plasma cutting machine manufacturers will brief you on the CNC plasma cutting machine optional plasma cutting machine power supply should meet the requirements, as follows:
1. According to the arc start-up method, plasma power supply has two types: contact arc and non-contact (button) arc. For CNC devices, you should choose a contactless arcing method. To determine which arc discharge method the plasma power supply belongs to, you only need to check if there is a button on the equipped flashlight. Typically, a plasma power supply with a current greater than 100A is a non-contact arc start-up method.
2. Choose the plasma power current size based on the thickness of the plate to be cut.
3. According to the quality requirements of the cutting part, choose the type of plasma power supply and manufacturer. CNC plasma cutting machine because the upper surface is large and the lower surface is small, so the cutting part always has a certain tilt, can not be as vertical as flame cutting. This is a world problem. Normal plasma with a tilt of 15 degrees. The plasma power supply is divided into ordinary plasma, fine plasma and laser-like plasma according to the verticality and cutting accuracy of the cutting part. At the same time, its prices vary widely.
4. Plasma power supply has inverter type and thystor type, the former is light weight. Plasma power supplies can be used between manual cutting and CNC plasma cutting machines. In order to achieve the torch clamped to the CNC plasma cutting machine, purchase should be equipped with CNC straight handle torch.
5. taking into account the temporary load rate, the general household power supply is about 80%, the better imported power supply can reach 90% or even close to 100%. (Temporary load rate, also known as load sustainability, refers to the ratio of the equipment's operating time at full load) 6. The length of the plasma cable should take into account the distance between the torch and the plasma power supply throughout the cutting process. However, the length of the cable reduces its arc perforation and cutting capability.
