Introducing the Lightning Series: The Only Orbital Weld Head for Copper

Critical Systems, Inc. (CSI) is thrilled to announce the official launch of the Lightning Series (LS) Weld Head—the first and only orbital welding equipment capable of welding copper using patented technology. For the first time in the industry, welders, engineers, and fabrication specialists have access to a solution that delivers clean, strong, and consistent copper welds with unmatched ease and safety.

The Game-Changer in Orbital Copper Welding

With the Lightning Series, CSI introduces a revolutionary solution that combines advanced orbital fusion welding with breakthrough heat management and design innovations—that make copper orbital fusion welding a reality.

Why the Lightning Series is the New Industry Standard

• Patented Super Cooling System

  Enables high-amperage orbital welding of copper without compromising performance—something impossible before now.

• All-Metal Construction

  Designed for heat dissipation, durability, and performance, the LS weld head is the first 200-amp, closed arc orbital weld head of its kind.

• Ceramic Rotor Heat Shield

  Proprietary, long-lasting component that minimizes wear and supports consistent high-performance welds.

• Plug-and-Play Precision Cassettes

  Patented, self-aligning collets with enhanced gas channeling for superior shielding and weld coverage.

Why Orbital Welding Matters—Especially for Copper

Orbital welding is a fusion-based, filler-free process that offers superior cleanliness, strength, and repeatability. Using a gas tungsten arc welding (GTAW) method and advanced programming, orbital systems create leak-tight, homogeneous welds that outperform brazed connections in critical gas, chemical, and medical gas lines.

With copper's high thermal conductivity, orbital welding was previously out of reach—until now.

Benefits You Can Expect

• Stronger welds with lower leak rates

• Safer operations with no filler metals or open flames

• More Efficient training and operation—perfect for high-throughput teams

• Documented programming and repeatable quality

• Fully protected weld zones with inert gas shielding

Whether you're working with ultra high purity gas lines or building next-gen clean process equipment, the Lightning Series helps you get it done faster, cleaner, and more reliably.
