INTRODUCTION

Electrical and electronic devices associate electric shock phenomena. The electric field located near a conductor can be too concentrated to ionize the air that is near the conductors and generate a current called the Corona Effect. The main objective is to lower the noise levels generated by high voltage transmission, avoiding energy losses, damage to electronic circuits and fractures in the laser tube. The electrical current is transferred through voltage lines and the connectors have the function of guaranteeing the continuity of the current, if the connectors are damaged or dirty, the continuity of the current is compromised, and the energy creates new conduction routes ionizing the air and creating discharges around the connections.

High voltage cables for CO2 machines are covered with a dielectric that guarantees the conduction of current through the conductive cable, over time the connectors and cables lose their properties and allow the current to ionize the air and produce jumps of current, which is necessary to review periodically and make changes if necessary, adding silicone coatings, to avoid power losses and future designs in the tube

DEVELOPMENT

Current jumps in the high voltage cable and laser tube.

CAUSES:

 1.    Deteriorated high voltage cable terminals

 2.   Excessive pollution around the laser tube

 3.   Excessive pollution in the high voltage cable

 4.   High cable in bad condition

   Cable Life Cycle (Finished)

 5.   The high voltage cable without silicone coating

 6.  The high voltage cable too close to the power source or metal parts

SOLUTION

 1.  Clean the laser tube from pollution 

 2.  Clean the high voltage cable from pollution 

 3.  Keep the high voltage cable away from metal parts and power source 

 4.  Coat the high voltage cable with silicone or silicone hose to create greater insulation.

 5.  Apply WD-40 moisture shifters to fittings

 6.  Cover the anode and cathode connectors with Thread seal tape to avoid failures in power continuity, generated by pollution

   1.   Pollution or cutting residues that accumulate in the connections interrupt the flow of current and generate power surges.

.  2.  High voltage current requires dielectrics for optimal operation.

   3.  Properly insulating all connections with Thread seal tape helps prevent current surges.

   4.  Periodic maintenance on high voltage cables and connections is essential to take care of current surges.
