Inventory for Your Spot Welding Infrastructure

High-Performance Components to Keep Your Production Moving


A resistance welder is a complex system of electrical and mechanical components that must work in perfect synchronization. When a single cable fails or a transformer loses efficiency, your entire production line can grind to a halt. At Spotco, we maintain an extensive inventory of resistance welding parts and accessories to ensure you have immediate access to the critical components that keep your machines operational.


From high-flexibility secondary conductors to advanced digital controllers, we stock only the highest industrial-grade parts. Our goal is to provide a one-stop-shop for maintenance teams and plant managers who require fast turnaround times and technical reliability for their spot welding infrastructure.

Components for Resistance Welding

We stock a wide range of essential accessories designed to optimize power delivery and process control.


High-Flexibility Cables & Laminated Shunts

Efficient power delivery starts with your secondary conductors. We provide a full range of high-performance cables and shunts:

  • Air Cooled & Water Cooled Cables: Designed for maximum conductivity and thermal management.
  • Dual Conductor Kickless Cables: Ideal for high-repetition tasks where cable "kick" must be minimized for operator safety and longevity.
  • Laminated Copper Shunts: Custom and standard shunts that provide the necessary flexibility for moving welding heads while maintaining a solid electrical path.

Advanced Spot Welding Controls & Entron Systems

The "brains" of your machine define your weld quality. We are a trusted provider of Entron spot welding controls, offering both basic and sophisticated digital units. Whether you need a simple AC control or a complex system with integrated monitoring, our control solutions ensure precise timing and current regulation for every weld cycle.

Industrial Water Recirculators & Cooling Systems

Excessive heat is the primary enemy of welding equipment. We stock Dynaflux Water Recirculators and cooling systems designed for various machine sizes:

  • TIG & Light Duty: 2-gallon systems for up to 250 AMP applications.
  • Medium Duty (Up to 60 KVA): 3-gallon reservoirs with high-efficiency cooling for standard spot welders.
  • Heavy Duty (Up to 150 KVA): High-capacity 15-gallon systems with up to 30K BTU cooling for large-scale production welders.

Copper Bar Stock & Refractory Metals

For facilities that manufacture their own custom tooling, we supply premium Copper Bar Stock and Refractory Metals. Available in various alloys and custom cuts, our raw materials provide the high hardness and thermal conductivity required for custom-built electrodes, backing bars, and projection welding fixtures.

Specialty Tools for Precision Finishing


Beyond the welding cycle itself, the finish of your workpiece matters. We offer specialty equipment like the Heat Tint Removal (HTR) Machine. This HTR-120 solution and its associated accessories allow for the rapid removal of heat discoloration on stainless steel and other alloys, ensuring your finished product meets the highest aesthetic and structural standards without the need for harsh chemicals or grinding.

  • What are the benefits of kickless cables?

    Kickless cables use a dual-conductor design that cancels out the magnetic "kick" produced during high-current welds. This reduces operator fatigue and extends the life of the cable by minimizing mechanical stress.

  • How do I choose the right water recirculator for my welder?

    Recirculators are sized based on the KVA of your machine and the BTU load of your production. For example, a 60 KVA welder typically requires at least a 3-gallon reservoir with a high-efficiency pump.

  • Do you sell raw copper for custom tooling?

    Yes. We stock copper alloys and refractory metals in various bar, rod, and disc sizes. We can provide custom cuts to match your internal fabrication needs.

  • What is a Heat Tint Removal machine used for?

    It is an electrochemical tool used to quickly clean and passivate welds on stainless steel, removing the "rainbow" heat tint without scratching the metal surface.

  • Can you help me replace an old Entron control?

    Absolutely. We can cross-reference your current control model and provide a modern Entron replacement that fits your existing machine footprint and electrical requirements.

  • Do you stock laminated shunts for custom applications?

    Yes. We can provide standard shunts or work with you to manufacture custom-sized laminated copper shunts based on your specific length and hole-pattern needs.
