Symptom Unstable cutting air pressure, pressure alarm, intermittent air output, no gas discharge, abnormally high gas consumption, and fluctuating cutting section quality.     Possible Causes Insufficient gas cylinder pressure, valves not fully opened, or improper switching of the cylinder manifold. Damaged pressure reducing valve, fatigued pressure regulating spring, resulting in continuous output pressure drift. […]

The machine bed is the base of the fiber laser cutter. A dirty or deformed bed directly affects cutting accuracy and workpiece flatness.     Daily Check Clear metal slag and scraps on the worktable after each batch cutting. Check support strips for burning damage or deformation. Confirm no leftover parts jammed in the bed […]

The chiller cools the laser source and cutting head. Overheating will trigger alarms, reduce laser output stability and even damage the laser.   Common Symptoms High temperature alarm pops up Unstable water temperature fluctuation Low water flow warning Water leakage   Possible Causes Dust clogging on condenser Insufficient or contaminated circulating water Water filter blocked […]

Burrs are the unwanted metal residues attached to the edge of laser cut workpieces. It increases secondary polishing workload and affects product quality.   Common Symptoms Hard metal slag sticks to the bottom of cutting edge Rough, uneven cutting surface Burrs appear intermittently during cutting   Possible Causes Incorrect gas pressure or gas purity Cutting […]

Height following system keeps consistent distance between nozzle and sheet. If it fails, you will get bad cuts, nozzle collision and machine damage.   Common Symptoms Nozzle hits the metal plate Unstable cutting height during processing Height reading jumps randomly Alarm triggered when starting cutting   Possible Causes Dust, spatter or residue on the capacitive […]

The laser cutting head is the core component of your fiber laser machine. Proper daily maintenance avoids sudden downtime and reduces costly part replacement.     Daily Check Inspect the protective lens for dust, oil stains or scratches. Replace immediately if damaged. Check the nozzle for deformation, clogging or residue buildup. Clean or swap nozzles […]

High‑reflective materials such as copper, brass, and aluminum are always challenging for fiber laser cutters. Strong reflected laser light may bounce back toward the laser source, which could potentially damage your laser generator.     Main risks of high‑reflective material cutting Back‑reflected laser energy returns to the laser head and resonator. Unstable cutting results: rough […]

Introduction Edge defects are the most common problems in daily laser cutting production. Rough edges, longitudinal stripes, edge burning, burrs and oxidation discoloration often lead to rework, low yield and increased post-polishing workload. Most edge quality issues are not caused by machine failure. They come from incorrect parameters, poor gas stability, worn accessories and improper […]

Introduction Material waste is one of the biggest invisible losses in metal processing. Many laser cutting workshops face high scrap rates and low material utilization, which directly reduce profit margins. Most cutting scraps are not caused by machine failure, but by unreasonable nesting, improper operation and material management problems. This article shares practical methods to […]

Introduction High nitrogen consumption is one of the biggest hidden costs for laser cutting workshops. Many factory owners find their gas bills extremely high without knowing the exact reasons. Unreasonable parameter settings, equipment problems and improper operation all lead to gas waste. This article summarizes the main causes of excessive gas consumption and shares practical […]

Introduction When buying a fiber laser cutter, you need to decide between a single platform and exchange table model. Both cut metal accurately, but they differ in efficiency, cost and use cases.   1. Single Platform Laser Cutting Machine It only has one worktable. The machine must stop for loading and unloading sheets after each […]

Auxiliary gas is a critical factor that directly decides cutting edge quality, processing speed and operating cost for fiber laser cutters. Many fabricators pick gas only by experience, which easily leads to poor workpiece finish, excessive consumption and higher production expenses. Understanding the features and suitable scenarios of each common auxiliary gas helps you make […]

Modern fiber laser cutting machines are equipped with intelligent alarm systems to protect core components from damage. Operators often panic when error codes pop up on the control screen, stopping production suddenly. Most alarms do not represent serious breakdowns. You can solve basic failures quickly with standard troubleshooting steps and resume production without waiting for […]

Introduction Traditional metal tube and profile processing relies heavily on manual cutting, sawing and secondary finishing, which leads to low precision, messy notches, heavy burrs and slow production efficiency. For structural steel profiles including square tubes, rectangular tubes, channel steel and H-beams, conventional processing methods struggle to meet the high-precision sizing, hole punching, grooving and […]

Introduction With the continuous upgrade of metal fabrication standards, conventional fixed-beam laser cutting faces obvious limitations when processing mixed materials and variable-thickness plates. Traditional laser beams feature a single energy distribution, which often leads to poor section flatness, edge oxidation, burr residues, and unstable cutting results when working with thick plates, thin sheets, or high-reflection […]

Introduction Traditional laser cutting only produces vertical edges, requiring additional manual chamfering, milling and grinding for welding preparation. For structural steel, engineering machinery parts and thick plate components, secondary bevel processing consumes massive labor and time, greatly delaying delivery cycles and increasing production costs. Laser bevel cutting technology has gradually become a standard solution for […]

Introduction Carbon steel and stainless steel cutting is relatively mature and stable for most fiber laser machines. However, processing highly reflective metals such as aluminum, copper, and brass has always been a major technical challenge for metal fabricators. High-reflection materials easily reflect laser beams back to the laser generator, causing unstable cutting, poor edge quality, […]

Introduction Incomplete cutting is one of the most frequent and troublesome failures in daily fiber laser processing. Many fabricators encounter situations where the laser cannot cut through metal plates, resulting in unseparated workpieces, continuous material connection, scattered cutting sparks, and low finished product yield. Incomplete cutting is not always caused by machine breakdown. Most problems […]

Introduction Stainless steel laser cutting is one of the most common yet challenging processes in metal fabrication. Unlike carbon steel, stainless steel features poor thermal conductivity and high melt viscosity, making it prone to dross adhesion, edge burrs, and rough cutting surfaces. Excessive burrs and slag will lead to time-consuming secondary polishing, increased scrap rates, […]

Introduction Buying a fiber laser cutting machine is a significant capital investment for metal fabrication workshops.
