Why Does One Side Have Dross While the Other Side Looks Clean?

If one side of your cut has heavy dross while the other side looks clean, don't change your parameters blindly.

First, check the nozzle condition.

Spatter build-up or a deformed nozzle tip can affect cutting stability and gas flow.

Clean or replace the nozzle if the tip is contaminated or damaged.

Next, check nozzle alignment.

A misaligned nozzle can affect the gas flow around the cutting point and lead to inconsistent cutting results.

Then inspect the protective lens.

Contamination or burn marks can affect beam transmission and cutting stability.

Finally, check the cutting speed.

If the speed is too high for the material and thickness, reduce it and fine-tune the setting.

Check the actual cause first, then adjust one factor at a time.

We supply compatible laser spare parts and consumables for different laser systems.

Why Is Your Laser Not Cutting All the Way Through?

If the laser starts cutting but the material isn't fully separated, don't change every parameter at once.

First, check the cutting speed.

If the speed is too high, the laser may not have enough time to cut through the full material thickness.

Try reducing the speed gradually and check the result.

Next, check the focus position.

An unsuitable focus position can reduce cutting efficiency through the plate.

Fine-tune the focus according to the material thickness and cutting setup.

Then inspect the protective lens.

Contamination or damage can reduce beam transmission and affect cutting performance.

Check the lens for contamination, burn marks or damage.

After that, check the assist gas.

Gas pressure, flow and purity can affect how effectively molten material is removed from the cut.

Finally, inspect the nozzle.

A damaged, contaminated or misaligned nozzle can affect gas flow and cutting stability.

Make adjustments step by step and identify the actual cause first.

Burnt or excessive burrs on sharp corners?

Sharp corners can behave differently from straight cutting paths. When the cutting head slows down and changes direction, local heat input can increase and affect the corner quality.

If you are getting burnt corners or burrs, try these process adjustments:

• Add a cooling point at critical corners to reduce heat build-up
• Add a small corner radius where the design allows it
• Adjust corner speed or power control to reduce excessive heat input

If the problem still remains, check the cutting head condition, nozzle size and condition, assist gas flow, and protective lens for contamination.

The right process settings come first. Consumable condition also matters when troubleshooting cutting quality.

Why does cutting quality change across the same sheet?

The machine, program and parameters may stay the same — but the actual cutting conditions can still change from one area to another.

Common factors include:

• Heat build-up
• Cutting sequence and path
• Workpiece deformation
• Cutting-head condition
• Nozzle and protective lens condition

This is why changing parameters immediately is not always the best first step.

First identify what has changed in the cutting process, then make targeted adjustments.

Same settings, but the cutting result gets worse after running for a while?

If the parameters haven't changed, don't assume the settings are the only problem.

During continuous cutting, check what may have changed:

• Protective lens condition
• Nozzle wear or deformation
• Assist gas stability
• Cutting head condition
• Actual operating conditions

A cutting system can change during operation even when the programmed settings stay the same.

Before making major parameter adjustments, identify what changed first.

Burnt and yellow edges when cutting carbon steel with oxygen?

This issue can be related to several cutting conditions — not just one parameter.

Check these five factors:

• Cutting speed
• Laser power
• Assist gas pressure and purity
• Focus position
• Consumable condition

Before making large parameter changes, check each factor and adjust according to your material, thickness, and cutting setup.

A worn or contaminated consumable can also affect the final cutting result.

Why does the cut start leave a burn mark even when the rest of the edge looks fine?

A visible burn mark at the start point can be caused by excessive heat during piercing or the transition into cutting.

Before replacing parts, check:

• Piercing and start settings
• Cutting speed and laser power
• Focus position
• Assist gas conditions
• Nozzle condition and coaxial alignment

The key is to identify the cause instead of changing parts blindly.

We supply compatible laser parts for major fiber laser cutting systems, including laser nozzles, protective lenses, ceramic rings and other laser parts for Raytools, WSX and Precitec.

Why Does the Laser Cutting Head Suddenly Hit the Sheet?

A cutting head collision can have several causes. Warped or lifted material, residual cut parts, unstable height sensing, or damaged cutting head components can reduce the clearance between the nozzle and the sheet.

Before continuing to cut, check the sheet condition, height following, and cutting head components.

We supply compatible ceramic rings, laser nozzles, protective lenses and other laser parts for major fiber laser cutting systems, including Raytools, WSX and Precitec.

Can a Worn Nozzle Change Your Cutting Result?

A worn or damaged nozzle can disturb assist gas flow and affect cutting stability. If cutting quality changes unexpectedly, dross increases, or the result becomes unstable, the nozzle condition is worth checking.

Why Are Your Cut Edges Getting Rougher?

Rough burr edges killing your laser cutting quality?
Many operators blindly tweak machine parameters first, but that’s not always the fix.

Rough cutting edges can come from several factors:
✅ Material type & thickness
✅ Wrong cutting speed / power / focus settings
✅ Worn or dirty laser consumables

Before you change any parameters:
1️⃣ Check your actual cut edge result
2️⃣ Confirm material and plate thickness
3️⃣ Review your cutting parameters
4️⃣ Inspect nozzle and protective lens for wear & contamination

If your consumables are worn out, low‑quality parts will keep giving you poor cuts.

We supply compatible laser nozzles, protective lenses & ceramic rings.
Fit for Raytools, WSX, Precitec, BOCI and more fiber laser cutting heads.
