- Semiconductor and ultra-pure gas systems: Orbital TIG welding of small-diameter stainless steel tubing in cleanroom environments where weld repeatability and traceability are mandatory.
- Pharmaceutical and biotech piping: Welding sanitary stainless steel process tubing to 3-A, ASME BPE, and ASTM standards, where consistent ID weld profiles are required.
- Aerospace tube assemblies: Joining hydraulic lines, fuel tubing, and instrumentation lines where full-penetration, defect-free orbital welds must meet stringent quality codes.
- Power generation and HVAC: Automated orbital welding of pressure tubing, heat exchanger tubing, and instrumentation lines for power plant and industrial applications.
The Cobratig 150 is an orbital TIG power supply designed to drive MK Products' family of orbital weldheads, including the Mini Micro Orbital Weldhead (part 4000) and other MK Cobratig-compatible weldheads. It is intended for use with the Cobraturn T-260 digital turntable (127-008) for full workpiece rotation control.
The Cobratig 150 is not a general-purpose TIG welder — it is a dedicated orbital welding system component. It requires MK Products-compatible weldheads and interface cables; it is not compatible with generic TIG torches or non-MK weldheads without verification of connector and protocol compatibility.
For a complete orbital welding station, you will typically need: Cobratig 150 power supply, a compatible MK orbital weldhead, and the Cobraturn T-260 turntable (for workpiece rotation). All are available at WeldingMart — MK Products.
WeldingMart is an authorized MK Products distributor with access to the full Cobratig orbital welding product line — power supplies, weldheads, turntables, cables, and consumables. Our team can help you design a complete orbital welding station matched to your application, tube diameter, and production volume. We ship MK Products equipment from our US warehouse with competitive pricing and knowledgeable pre-sale support — no guessing about which components pair together.
