First, We do not recommend you retrofit anything to our welders. That can and will void the warranty, especially when it is damaged.

The DINSE configuration is the most widely used plug adapters in the world. I'm not sure what all you are talking about. I think you are making it overly complicated and likely will confuse many people. It's not that hard.

I've been around a long time and DINSE are defined in multiple ways, but the most common way they are defined is by the cross section of the cable. With that said, they are two common sizes, 3/8" diameter pin, and a 1/2" diameter pin. (nominal). These are often listed by the pin size too. These pin sizes are generally related to amperage with the 3/8" used on less than 200 amp equipment, and the 1/2" diameter is used on up to 400 amp capacity machines. The back end of the cable connection is the only difference. That is why you'll see it often as DINSE 15/25 or DINSE 35/50 or DINSE 50, or DINSE 50/70. Every manufacturer deals with the numbers a bit differently. All of which we use, but really doesn't matter that much unless you need to change a cable out, which isn't recommended

Miller, and Lincoln also use these. The word "type" is often accompanied by the use of the word DINSE as there are many manufacturers that will typically interchange with one another, but DINSE is the biggest and frankly, it is an open source design that has been around for 30 or 40 years.

The best resource is here, on page 18. And if a person wants "aftermarket" DINSE type, this is the place to go. https://profax-lenco.com/catalog/
