Common problems with laser cutting machines
I. How to Choose a Suitable Laser Cutting Machine
The judgment is mainly based on three directions:
I. Cutting materials (carbon steel, stainless steel, aluminum, copper, etc.)
II. Sheet thickness
III. Production Quantity RequirementsSimple judgment:
Carbon steel 1–20mm: 3000W–6000W
Stainless steel 1–12mm: 3000W–6000W
Thick plate 20mm and above: 12000W–30000W
Mass production: High power combined with automated equipmentII. Differences between Bentech Laser and other brands
Firstly, high-wattage lasers have excellent stability.
Secondly, it offers high cost-effectiveness with low consumable and maintenance costs.
Thirdly, local services in Taiwan are fast.Third, is it because Chinese brands are of lower quality?
Bentech Laser is one of the top three brands in China and has the highest market share in Taiwan for high-wattage lasers.
In recent years, the technology has reached the international mainstream level, and Quan Zeng Precise provides local after-sales service and installation and maintenance.IV. What are the consumables for laser cutting machines?
Protective lenses
nozzle
filter element
Cutting gases (nitrogen, oxygen, air)The cost of consumables mainly depends on the stability of the cutting head, the cleanliness of the optical path, and whether the parameter settings are correct.
V. Differences between nitrogen, oxygen, and air
Nitrogen: Non-oxidizing, suitable for stainless steel and aluminum, produces a beautiful cross-section.
Oxygen: Reactive cutting, fast speed, suitable for thick carbon steel plates, the cut will turn black.
Air: Lowest cost, suitable for thin sheets, but requires compressed air equipment.VI. Electricity Demand
Most laser cutting machines are three-phase 380V.
If the site only has 220V, a transformer is required.VII. Maintenance Contents
Check your protective lenses daily.
Cleaning the cutting head
Confirm gas stability
Apply oil to the guide rail
Dust collection equipment cleaning
Cooling water system water replenishment and regular replacementMost importantly, it is about operator training and familiarity with the parameters.
8. Does it provide education and training?
We provide comprehensive training, including operation, parameter settings, typesetting software, maintenance methods, and on-site trial cutting.IX. Warranty Coverage and Repair Speed
The standard warranty period is one year.
The cutting head varies depending on the brand.
Laser units have a warranty period of 12 to 24 months, depending on the model.
Quan Zeng Precise has a local repair team in Taiwan, so they respond quickly.10. Does the company assist with factory planning?
We can assist in providing machine configuration, workflow suggestions, air compression requirements, smoke extraction design, voltage stabilizer recommendations, and mass production implementation. - Welding Workbench Buying Guide

Common problems with welding workbenches
1. What are the differences between D16 and D28?
D16, 16mm diameter, suitable for small to medium-sized workpieces.
D28 has a 28mm bore diameter and is suitable for large and heavy workpieces.
D28 has significantly higher load-bearing capacity.II. How to Choose a Welding Table
Check the size, weight, and precision of the workpiece.
For small workpieces, select D16.
Select D28 for large or heavy structural components.3. What are the differences between your welding tables and imported brands?
Specifications compatible
More competitive prices
Consumables and after-sales service can be handled in Taiwan.
Fast deliveryIV. Will welding tables rust?
Surface treated
It is not easy to rust under normal use
In humid environments, it is recommended to wipe and oil the surface regularly.V. What maintenance is required?
Keep dry
Wipe regularly
Remove welding slag
Apply a thin layer of rust-preventive oil.VI. How to select jigs
Basic fixtures are sufficient for most workpieces.
Squares and corner pieces fit the frame
Heavy-duty component strong fixing jig
We can provide photos of the workpiece if needed, and we can also provide professional services.
Comes with a complete set of accessories7. Is customization possible?
Customizable dimensions, hole positions, and table leg height.
It can also be paired with exclusive jigs8. How long is the delivery time?
Standard size fastest
Custom orders will take some extra time depending on the requirements.
