View Full Version : Miller TIG pedal--> 14 pin to 6 pin

Hi all,

Long time reader, occasional poster.

Has anyone here adapted a Miller 14 pin pedal to a 6 pin machine? I'm switching out my Syncrowave to a Maxstar... space limitations... I'd like to avoid having to buy a $225 pedal to go with it. I would assume it's mostly a matter of figuring out which wires are what and splicing into a new DIN connector?

Thanks in advance!

Well, looks like I answered my own question. Miller has a wiring diagram with both the 6 and 14 pin diagram on the same page...

Just need to order a connector and I'm in business.

Thought I'd post any progress I make, in case someone else wants to pursue this...

Found this company via Ebay and followed the pedal to their website where they sell the connectors: http://www.ssccontrols.com/index.htm

I'm thinking about making an adapter with a male 14-pin plug on one end and 6-pin female plug on the other... cleaner and more flexible than lopping the 14-pin off (and if I ever switch back to a welder with 14-pin remote, it's easy to switch back).

Will update further as things move forward...

Sorry nobody could help you with that. But please post up, it's good for future reference!

And SSC Controls is local for me, they make nice stuff! I have one of thier foot pedals, top notch quality.

Just thought I'd finish this post in case anyone is looking to do this...

I bought a 6-pin connector from SSC controls. It had a 2' pigtail on it... $30.

I gave up on making an adapter cable as it would have cost about $75 for the connectors. Anyhow, I cut the 14-pin from the pedal and wired it all up referencing SSC's documentation and Miller's to get the wires connected right.

First arc: hit the pedal and got full current at the top of the stroke, min at the bottom. Ooops. Easy fix:

Pins 3-4 should read 1,000 ohm (plus or minus 10%) with the pedal in the upright position. This is the red and green wires for the Miller model.
Pins 3 and 4 for the SSC setup are blue and brown. However, the main thing is that the Miller have 1000 ohms between pins 3 and 4 with the pedal up. As the pedal is pressed, this should go to zero.

Second arc: success! The little Maxstar welds pretty good... not as good as my old Syncro, but at a 1/8th the weight and size, it's pretty cool (and I can run it on 110 or 220!).
