Quick look! The consumption of consumable parts cannot be ignored, or it may become a cutting flaw!

During the cutting process, have you ever encountered the following problems: the power supply and cutter are working normally, and the cutting parameters are set accurately, but the cutting quality is not satisfactory? Maybe it's time for you to check the consumables status! Abnormal consumption and breakage of consumable parts are key factors affecting cutting quality. 

Don't do something small! The consumable parts are small, but they are the most important part to determine the cutting quality! Everyone must check regularly and replace them in time!

Today, the editor will take you to take a look at the life consumption status of various wearing parts, help you understand the consumption and damage of various wearing parts, and improve your cutting quality.

1、Electrode consumption status

Electrode normal consumption

Electrode life is not used up

Electrode overuse

Beyond normal depletion depths, the arc energy burns the copper or silver surrounding the hafnium core, causing the "electrode pit" to expand.

Electrode life is not exhausted, used up, overused comparison

Abnormal consumption of electrodes - eccentricity

It is often caused by damage to the swirl ring or unstable plasma gas flow.

Spiral black marks on electrodes

Black marks are caused by poor cutting gas quality (impurity oil) or dirty hands when installing consumable parts. If this trace appears, accompanied by short nozzle life or arcing problems, you also need to consider insufficient plasma gas or damaged torch.

2、Nozzle Consumption Status

Nozzle normal consumption

Nozzle is about to run out

Nozzle overuse

Nozzle external damage (external round hole is not round)

   

White hafnium buildup inside nozzle (normal)

3、Protective cap consumption status

Protective cap slag

If the accumulated slag is not cleaned in time, it will block the protective gas and cannot blow away the anti-slag during cutting in time, shortening the life of wearing parts.

The protective cap was damaged by the tilted steel plate

4、Swirl ring consumption status

Swirl ring damage

Generally, the eddy current ring is difficult to be damaged without external force. It is often caused by strong extrusion during installation, or damage after collision during cutting. Be sure to apply silicone grease to the eddy current ring during installation to increase lubrication.

     

5、Fixed cap consumption status

Damaged internal fixation cap

Damaged external fixation cap

   

The consumption of wearing parts should not be underestimated, and they need to be replaced regularly in order to better ensure cutting efficiency and obtain better cutting results.
