In the world of sheet metal fabrication, staying competitive means keeping your equipment in top shape. However, purchasing a brand-new plasma cutting table can be a significant investment—one that might not always be necessary. Retrofitting your existing plasma table is a cost-effective way to improve performance, minimize downtime, extend its lifespan and enhance your shop’s overall efficiency.
What is Retrofitting?
Retrofitting involves upgrading or modifying an existing plasma cutting system with modern technology. This can include replacing outdated CNC controls, upgrading the cutting torch, enhancing software, or improving motion control components. Rather than investing in an entirely new system, retrofitting allows you to leverage your existing infrastructure while gaining access to cutting-edge features.
Key Benefits of Retrofitting a Plasma Table
1. Cost Savings Compared to New Equipment
A full plasma table replacement can be costly, not just in terms of the machine itself but also in downtime, installation, and training. Retrofitting can cost a fraction of a new machine while delivering comparable performance improvements and extending the life of your current table.
2. Improved Cutting Precision and Quality
Older plasma tables may struggle with accuracy due to wear and tear on mechanical components or outdated control systems. Upgrading to a modern CNC system with improved drive motors and controllers can enhance precision, leading to cleaner cuts and less rework.
3. Increased Cutting Speed and Efficiency
Advancements in plasma technology have led to faster cutting speeds with better control over arc stability. By upgrading to a high-definition plasma torch or a newer power supply, you can achieve faster production cycles without sacrificing quality.
4. Enhanced Software Capabilities through PractiCAM
Modern nesting and CNC software, such as PractiCAM, offer significant advantages over older versions. Retrofitting allows you to integrate advanced software features such as automated nesting, real-time monitoring, and improved motion control, making programming and operation more intuitive and efficient.
5. Reduced Downtime and Maintenance Costs
Outdated plasma systems often require frequent repairs and maintenance, leading to production slowdowns. Newer components are designed for higher durability and efficiency, meaning fewer breakdowns and lower long-term maintenance costs.
6. Adaptability to New Materials and Applications
If your current plasma table struggles with cutting new or thicker materials, a retrofit can provide the necessary power and precision. Upgrades like a more powerful plasma source or a better torch height control system allow you to expand your capabilities without needing a new machine.
What Can Be Upgraded in a Plasma Table Retrofit?
A retrofit can involve various components, depending on your needs and budget. Some of the most common upgrades include:
• CNC Control System – Replacing an outdated controller with a modern CNC system improves precision, automation, and ease of use.
• Plasma Power Supply – Upgrading to a high-definition or newer plasma source enhances cut quality and speed.
• Torch and Consumables – A new torch with better consumable management reduces operating costs and improves cutting performance.
• Servo Motors and Drives – Improving motion control ensures smoother cuts and better reliability.
• Software Upgrades – New software and CAD/CAM integration streamline production workflows.
• Fume Extraction and Safety Features – Upgrading ventilation systems improves workplace safety and compliance.
Is Retrofitting Right for Your Shop?
If your plasma table is struggling with accuracy, efficiency, or reliability but still has a solid frame and structure, retrofitting could be the ideal solution. By upgrading key components, you can achieve the performance of a new machine at a significantly lower cost.
