6 Pin Metal Plug and Clamp S12020-27 Connector for Lincoln TIG MIG Welder

This was a perfect fit for the pedal on my lincoln idealarc 250/250 ac/dc The product came brand new clean and ready to solder the new wires(I replaced the existing 6 wire cable from the machine to the pedal) on to the points. Just make sure to cut the existing plug off with some leads left onto it so you can match up the wires as need be. This resolved so many problems I was struggling with troubleshooting I can't even begone to tell you. If you have an older machine and it's doin funky stuff and never really putting that bead down like you remember you being able to do. Check your pedal. This has reminded me how good lincoln machines are and that I also do know what I'm doing around a tig machine after all. Haha

Muy buena calidad y buen precio

Engineering Evaluation Report Component: Circular Connector – 10 Pin (MIL-DTL-5015 Type) Application: General Aviation Electrical Harness 1. Objective The purpose of this evaluation was to assess the mechanical, electrical, and environmental performance of a 10-pin aviation cannon plug against the requirements for installation in general aviation aircraft systems. The connector under test was selected for potential use in engine instrumentation and cockpit harness assemblies. 2. Methodology 2.1 Mechanical Inspection Visual inspection for machining quality, plating integrity, and keying features. Measurement of shell dimensions and thread pitch. Evaluation of coupling torque and strain relief effectiveness. 2.2 Electrical Testing Contact resistance measured per MIL-STD-202 Method 307. Dielectric withstanding voltage (DWV) test up to 1500 V RMS. Insulation resistance measurement at 500 VDC under controlled humidity. Current rating validation at 13 A with 16 AWG conductors. 2.3 Environmental Testing Ingress protection (dust and water) per IP67 standard. Salt fog exposure (96 hours, per MIL-STD-810 Method 509.6). Hydrocarbon (aviation fuel/oil) exposure test. Vibration testing per MIL-STD-202 Method 204, Condition B. Thermal cycling between –55 °C and +125 °C. 3. Results 3.1 Mechanical Performance Coupling threads engaged smoothly without cross-threading. Positive keying prevented misalignment during mating. Strain relief clamp provided uniform stress distribution on conductors. Shell dimensions were within ±0.2 mm of nominal specification. 3.2 Electrical Performance Contact resistance: < 5 mΩ across all pins. Dielectric withstanding voltage: Passed 1500 V RMS without breakdown. Insulation resistance: > 5000 MΩ post-humidity exposure. Current carrying capacity: Maintained < 30 °C rise at 13 A per pin. 3.3 Environmental Performance IP67 sealing achieved when fully mated. No corrosion or plating degradation after salt fog test. Elastomers showed no swelling or loss of sealing after hydrocarbon exposure. No intermittent discontinuities detected during vibration test. No cracking or deformation observed after 25 thermal cycles. 4. Discussion The connector demonstrated robust performance across all mechanical, electrical, and environmental tests. The solder-cup contact design provided secure terminations but requires additional assembly labor compared to crimp-style systems. The connector’s shell size is larger than newer composite alternatives, but this results in improved pin spacing and easier termination inspection. The rated temperature ceiling of +125 °C may be a limiting factor for installations adjacent to turbine exhaust systems. For such use cases, higher-temperature connectors (e.g., MIL-DTL-38999 series) should be considered. 5. Conclusion The 10-pin aviation cannon plug (MIL-DTL-5015 type) meets all relevant electrical and mechanical requirements for use in general aviation electrical harnesses. It is recommended for applications in cockpit and engine bay environments where durability, legacy compatibility, and environmental sealing are required.

Have bought 9 of these and the first 4 I ordered were great but the last batch two the screws have stripped out on the part that holds the wire

A really nice connector for a good price - which I wasn't expecting. You see a lot of false promises on products like these nowadays, and I was expecting something pretty poor for the price. And honestly, I thought that's exactly what it was at first - thinking it was so caked with overspray that the threads wouldn't engage... A closer look showed it was a light dab of grease in the threads, to ensure proper threading on the first try. After a few more closer looks, I'm genuinely impressed at the quality at this price point.

What I like: This was another piece of my weldpak 180hd that I had to swap out along with the sleeve. Refreshed back to almost new after the original cable was ripped out by an elevator door. What I didn't like: Nothing to dislike, good value, solid connector.

This 6-pin metal connector works as expected with compatible Lincoln TIG and MIG welders. It matched up with the remote foot pedal and wire feeder without much trouble, and the overall design feels sturdy enough for light to moderate use. The clamp holds securely once everything is in place, and it’s functional for basic replacement needs. However, the finish on the connector wasn’t as refined as I expected. The threads felt a bit rough during installation, and some edges could have been better machined. It took some effort to get a snug, clean fit. While it does the job, it might not hold up to frequent plugging and unplugging in a heavy-duty shop environment. For occasional or hobbyist use, it’s a passable solution, but professionals may want to look at more polished options.
