                                                                   Apr 07, 2016    615 (3 Min Read)

                                                                  1. ensure the correct pressure and flow of the plasma cutting machine

                                                                  The correct air pressure and flow of the plasma is very important for the service life of the consumable parts. If the gas pressure is too high, the electrode life will be greatly reduced; the pressure is too low, the nozzle life will be affected. Reference to the use of plasma cutting machine instructions.

                                                                  2. using a reasonable cut distance for plasma cutting machine

                                                                  Cut away from the cutting nozzle and the distance between the workpiece surface and the distance as far as possible to maintain a constant, generally at about 3-8MM, too far the not only power consumption is too large, penetration of the cutting ability will decline, and relatively electrode consumption and the electrode life down; too close to the more simple, very nozzle, the service life of the nozzle will decrease exponentially, even loaded up burned; when perforation, as far as possible the use cut normal to the distance of 2 times the distance or by plasma arc can transfer the maximum height.

                                                                  3. perforation thickness and cutting thickness shall be within the allowable range of the machine system

                                                                  Plasma cutting machine can not be more than the thickness of the plate on the perforation, usually the thickness of the normal thickness of the thickness of the cutting 1/2. As far as possible in the plasma cutting machine rated normal cutting thickness cutting, try not to in the limit cutting cutting thickness, domestic cutting machine cutting thickness is generally manufacturers to mark the maximum cutting thickness of 60%, as far as possible in the range of the thickness of the cutting, can best protect the cutting nozzle.

                                                                  4. do not overload plasma cutting machine nozzles

                                                                  Let the nozzle overload (that is, over the working current of the nozzle), the nozzle will soon be damaged. The current intensity should be 95% of the working current of the nozzle. For example: the current intensity of the nozzle of the 100A should be set to 95A.

                                                                  5. keep the drying and cleaning of the plasma cutting machine gas

                                                                  Plasma systems need to be dry and clean plasma gas to work properly. Dirty gas is usually gas compression system, it will reduce the consumption of life, caused by abnormal damage. Method for testing the quality of gas cutting torch in the test state, a mirror is placed in the bottom of the, torch gas consumption, if there is a gas and mist on the mirror, you need to identify the reasons.

                                                                  What Are You Waiting For?

                                                                  Once You MakeYour Choice, Don't Agonize Over It.
