Knowledge That Plasma Cutter Operators Need to Have and Arc Break Analysis of Accessories

1. What knowledge do plasma cutting machine operators need to have?

If you want to make the best effect of the plasma cutting machine, not only the equipment is required, but also the operator's requirements are relatively high. So what knowledge do operators need to have?

First of all, it is necessary to have CNC process knowledge, programming ability, and operation skill level, so that the test piece can be processed with the most reasonable process plan, the best tool path and the shortest time.

Secondly, it is necessary to have the ability to master the rapid positioning of the workpiece. The most critical thing in technical preparation is to comprehensively use the basic knowledge of CNC application, so as to achieve the skilled operation of CNC machine tools. Alignment and clamping methods, reasonable selection of tools, optimal cutting parameters, and flexible use of CNC system functions to achieve fast and efficient machining.

In addition to the above two points, the plasma cutting machine operator needs to be skilled in operation and quick editing, select the entry point to complete the test piece, use the tool reasonably, optimize the cutting amount, ensure the key points, master the processing rhythm, separate the roughing and finishing, and strive to Complete the processing project within the specified time.

In fact, plasma cutting machine operators not only need to have the above knowledge, but also the ability to be flexible when encountering emergencies. For example, in case of emergency during operation, press the red emergency stop switch immediately to prevent accidents; if the pipeline is found to be backfired, power off immediately; before starting the machine, check whether there is air leakage in the machine pipeline, if there is air leakage, never start the machine.

2. What accessories of the plasma cutting machine will break the arc?

In the process of using the plasma cutting machine, if you are not careful, the problem of arc breakage is likely to occur. In order to prevent this from happening, let's take a look at which accessories will break the arc.

Part 1: The arc voltage height controller fails

As one of the accessories of the plasma cutting machine, the failure of the arc voltage height controller will also cause the problem of arc breaking. This is mainly due to the adjustment of the height of the plate and the cutting nozzle, which needs to maintain a stable equilibrium value. Plasma cutting machines have little problem when cutting flat plates, but if there is a problem with the arc pressure of uneven plates, it is easy to go wrong.

Accessory 2: Long perforation time

Setting the perforation time too long is also one of the reasons for the arc breakage. It is sufficient to adjust the perforation delay accordingly. In fact, in many cases, it is not necessary to set the perforation delay.

Accessory 3: The height of the cutting nozzle from the steel plate is too large

A major factor for the arc starting of the plasma cutting machine is the height of the cutting nozzle from the plate. In a few cases, the arc may have already started, but it is actually reluctant, so it may cause the sudden arc break during the cutting process.

If the above situation occurs, it is very likely that the plasma cutting machine will have an arc breaking problem.
