Among many cutting equipment, portable CNC plasma cutting machine is the most simple, convenient and practical cutting equipment in CNC cutting equipment, so portable CNC plasma cutting machine is also the most sought-after CNC equipment in the market. Pay attention to the installation of portable CNC plasma cutting machine. What is it? Which CNC cutting machine is better? Yunnan CNC cutting machine manufacturer Xiaobian brings you the following dry goods explanation:
Consideration should be given to connecting all metal parts in and around the cutting equipment. However, connecting metal parts to the workpiece will increase the risk of electric shock to the operator when they touch these metal parts and electrodes at the same time. The operator should be insulated from all metal parts connected in this way.
2. Ways to reduce emissions
Public power equipment should be connected to public power according to the manufacturer's recommendations. In the event of interference, further precautions may be necessary, such as filtering public power. For permanently installed cutting equipment, consideration should be given to using metal wire equivalent materials to shield the power supply cables. The shield should be connected to the cutting public power supply in order to maintain good electrical contact between the conduit and the equipment casing and the cutting power supply casing.
3. Shielding and shielding
Selectively shielding and shielding other cables and equipment in the surrounding environment may reduce interference problems. In special applications, it may be considered to shield the entire plasma cutting equipment.
4. Grounding of workpiece
If the workpiece is not connected to the ground for electrical safety, and because of its size and location, connecting the workpiece to the ground may reduce emissions in some cases, but this is not always the case. The user should take measures to place the risk of injury to employees or damage to other electrical equipment by grounding the workpiece. If necessary, the connection between the workpiece and the ground should be directly connected to the workpiece, but in some countries, direct connection is not allowed. At this time, the connection should be achieved by appropriate capacitors selected according to national regulations.
Note: The cutting circuit may be grounded or ungrounded for safety reasons. The decision to change the grounding arrangement must be evaluated and approved by professional staff.
