Retrofit - Adding a switch to a "looped" Miller 14 Pin
Should you have a Miller 14 Pin connector which has a wire loop already connecting pins A and B, this tutorial will give you the knowledge and parts to add a switch. A switch may be added if you come up to a newly designed machine qhich requires you to toggle off the contactor, then back on, in order to weld. In the picture to the right are four parts in total. A push button switch, a boot for the switch, and two inline connectors
The links to purchase these three individual parts are the following:

With the three links above, make note you need two 3M inline connectors, I will allow you to modify your looped miller adapter to give it a on/off switch. Do not strip the insulation off the wires
Step #1 is to cut the leads of the switch to 1.5” long each.
Step #2 is to cut the loop in half at a spot equaling the length of both looped, now individual leads.
Step #3 is insert one loop lead into the 3M connector and a switch lead, once both fully inserted, fully depress (I used pliers) the 3M connector. Refer to video
Step #4 Repeat step #5.
