Raysoar Maintenance Tips: How to Keep Your Gas Generator Saving Money, Reducing Worry, and Minimizing Hassle
In the fields of laser cutting and welding, have you ever experienced these frustrating moments: a once mirror-smooth cutting surface suddenly turns dark and rough; critical weld points develop porosity affecting strength; or at month's end, you find gas costs inexplicably soaring? These seemingly sudden "major issues" often stem from "minor oversights" in daily maintenance.
On-site gas generation systems are the "lifeblood" of your production line, and their stability directly determines processing quality and cost. Proactive maintenance is not an extra burden but a highly efficient investment—it helps you avoid unplanned downtime, reduce waste of expensive gas, and ensure the processing quality of every product. Based on experience serving thousands of customers, Shanghai Raysoar has compiled this practical maintenance guide to help you prevent problems before they occur and ensure your equipment runs stably and continuously.
Don’t Let "Minor Oversights" Lead to Major Losses
Many serious equipment failures and production losses can often be traced back to simple, routine items being overlooked. For instance, overdue filter service allows oil and moisture into the gas lines, not only contaminating the gas and affecting cut/weld quality but also potentially damaging the more expensive laser head lenses downstream, causing repair costs to skyrocket. Another example is slight inaccuracy in mixed gas ratios; in the short term, it might only mean reduced cut surface quality, but over time it leads to significant gas waste, silently eroding profits.
Raysoar advocates the "Preventive Maintenance" philosophy: through regular, simple checks and upkeep, investing minimal time and cost to lock in long-term equipment performance and avoid costly unexpected downtime and process failures. The following key points are essential for achieving this goal.
Detailed Product Maintenance Guidelines
Raysoar provides a full range of gas solutions for different process needs. The maintenance focus varies for each type of equipment. Please identify yours and focus on the key actions:

Core Function & Purpose |
Key Maintenance Actions |
|
High-Purity Nitrogen Generator |
Provides nitrogen with purity up to 99.99% for Bright Cutting of materials like stainless steel and for precision welding, which is key to high-quality processing. |
1. Regular Filter Replacement: Adhere to device prompts or recommended cycles for replacing pre-filters and precision filters. This is the first line of defense for purity. 2. Monitor Purity & Pressure: Daily checks on the device panel's purity display and ensuring outlet pressure remains stable at the set point. 3. Listen to Operation Sounds: Familiarize yourself with normal exhaust and cycle sounds. Unusual noises are often precursors to faults. Common Faults: 1. Decreased purity: Check filter cartridge → Air source pressure → Instrument calibration → Adsorption parameters. 2. Insufficient gas output: Check intake pressure → Pipeline leaks → Filter contamination → Compressor flow rate. 3. Equipment noise: Check motor bearings → Valve jam → Adsorption tower pressure imbalance → Pipeline vibration. |
|
Mixed Gas Generator |
Provides precisely proportioned nitrogen-oxygen mix for Fine Cutting with high-power lasers, optimizing cutting efficiency and edge quality. |
1. Avoid Unauthorized Adjustment: The mixing ratio is precisely set by Raysoar engineers. Users should not adjust it themselves to avoid affecting results and wasting gas. 2. Regular Seal Checks: Quarterly checks of all gas line connections with soapy water to prevent ratio imbalance and cost leaks due to leakage. 3.Regularly check the pressure of nitrogen and oxygen tanks to ensure stable operating pressure (1.6-2.6MPA). |
|
Air Cutting System |
Provides dry, clean compressed air for low-power cutting, offering a cost-effective cutting solution. |
1. Daily Drainage: Make it a habit to drain the refrigerated dryer and air tank before or after shifts to remove liquid water. 2. Regular maintenance of air compressors: Strictly adhere to the maintenance schedule, and perform periodic purging and cleaning of the radiator and filter. |
|
Dedicated Nitrogen Generator for Handheld Welders |
Provides portable, stable high-purity nitrogen shielding for mobile handheld laser welding equipment, ensuring quality for on-site and outdoor welding. |
1. Secure During Movement: Avoid severe impacts or vibrations when moving the equipment. 2. Inspect Hoses & Connections: Check hoses for wear/pinching and ensure quick-connect couplings are locked before and after operation to prevent leaks. 3.Make sure that the clean gas without oil and water enters the nitrogen generator. |
General Maintenance Schedule
Integrating scientific maintenance into daily routines is key to ensuring long-term equipment health. Here is a clear maintenance rhythm to help establish efficient upkeep habits:
|
Frequency |
Maintenance Item |
Key Points & Purpose |
|
Daily |
Operational Status Check |
Spend a minute observing for any alarm lights and listening for smooth operation. This is the most timely window to spot issues. Operational parameter monitoring: Record intake pressure (recommended 5-8 bar), exhaust pressure (recommended 4-7 bar), and nitrogen buffer tank pressure (20-25 bar). Compare nitrogen flow rate and purity data with the equipment's rated values to see if the purity is below the set value (e.g., 99%-99.99%). |
|
Daily |
Condensate Drainage, temperature of the dryer |
Drainage and Filtration System Inspection: Open the drain valves of the cold dryer, filter, and air receiver tank to completely discharge condensate water (to prevent water contamination of the nitrogen generator); |
|
Weekly |
Inspection of electric drain |
Inspect automatic or manual drainage valves such as filter dryers to prevent moisture accumulation that may affect gas drying efficiency. Clean equipment surfaces of dust and oil stains, and avoid scraping with sharp tools. Inspect the equipment casing. |
|
Quarterly |
Visual & Basic Performance Check |
Check that all pressure gauge readings are in the normal (green) range, confirm pipe connections are tight, and perform a simple system function test. For oil-lubricated air compressors, ensure the oil level is within the marked range. If low, perform timely maintenance and check if the rear filter is contaminated. |
|
Annually |
Professional Deep Maintenance & System Calibration |
This is the decisive step to restore equipment performance to its peak condition. Comprehensive performance testing: Record gas production, purity, and energy consumption data under full-load operation, compare with new machine parameters, analyze performance degradation causes, and develop optimization plans. Implement all required consumables replacement. |
Special Note on Annual Deep Maintenance:
Your excellent daily maintenance lays a solid foundation for equipment stability. Annual deep maintenance, however, is akin to a comprehensive "physical exam and precision tune-up" for your equipment. Its focus is on addressing core items requiring specialized tools and deep expertise:
1.Core Component Performance Evaluation: Professionals assess the efficiency of core components like molecular sieves or membrane separators, predict their remaining service life, and provide scientific forecasts.
2.Sensor & Valve Calibration: Ensures absolute accuracy of all sensing and actuation units for purity monitoring and flow control—the cornerstone of stable gas quality.
3.Complete System Leak Test: Uses professional methods to detect even the smallest leaks, eliminating invisible gas waste and purity risks.
4.Operating Parameter Optimization: Adjusts and optimizes equipment parameters based on your actual usage over the past year, making operation more energy-efficient and better matched to your production rhythm.
