Just need to figure out what wire goes to what pin.

Rather than try and suss out translating from whichever plug is on there - start with the pedal end - there should be six screws on the bottom of the pedal. Take it from there and then my photos of the pedal and diagrams (from Hood & my CnP from electronics stackoverflow) earlier in the thread.Just need to figure out what wire goes to what pin.
Fingers crossed it'll be easy enough to suss out, but if not, get a photo or two up here at the pedal end and I'll be happy to try to help if needed

That's an interesting question - I wondered the same and couldn't find a clear answer. I'd appreciate views on that from folk with extensive (i.e. >1 machine!) TIG experience too. Despite changing the cable on mine, I've not really used the pedal in any of my TIG practice. There's enough going on for now
The rotary does seems un-needed functionality on this type of welder where (at least according to the JASIC manual), max current is set at the machine. As you say, with this setup, that would just give you the facility to set a local, smaller max at the pedal. Could be handy; perhaps?
However, reading user reviews of some other machines suggests that when the pedal is used, the current setting at the machine is (or can be) ignored and this ranging pot sets the max current up to the welder's maximum output (e.g. https://www.mig-welding.co.uk/forum/threads/foot-pedal-control.93699/ ). Does this ring a bell from anyone's experience of other machines? Maybe if so, it's just cheaper to knock out a single pattern, cascading-pot, pedal?

Has anyone bought the DC only machines? I would be interested to know what they are like.

I never use a pedal on any machine so am not familiar with them but...
I presume you have the pedal connected, if so then try turning the pot on it to see if you get higher options.

As before, I've never really used the pedal in anger, but thought I'd try this. In both pulse modes, I see something similar.
The base/background value seems to be influenced by: max amps (some sort of percentage I think), and the position of the rotary pot on the pedal (vs its position when it was "calibrated" at remote 5s setup).
E.g. if it was connected (the 5s pedal hold down and beep) on full anticlockwise, turning it clockwise will allow slightly more adjustment to base/background.
Sounds a little similar to Hood's suggestion earlier; perhaps this is a common mode for pulse TIG pedals? The manual - even the JASIC - could be clearer on this - it says very lititle about.
[EDIT] - again a cross post with Hood!
[EDIT-2] - in fact, doing some internet searching suggests that some machines use the pedal to control background current when in pulse mode?! That would perhaps explain why the setting behaves that way, but I'd struggle to understand why anyone would *want* it to behave that way?

Yep this forum is the exact opposite of moneysavingexpert!
Hello people
First post on the forum, but just to say...
After umming and arring till my brain hurt. Finding this thread has encouraged me to cancel one order and order one of these today.
Complete noob, but really keen to learn to tig. So likely to be seeking advice from the collective fairly soon. Can’t wait

I think you will be happy with it, I am certainly not regretting buying it.
It is just so nice on DC, used to hate doing thin stainless sheet but now it is almost a joy
Been doing some more today, 1.5mm 316 with 38Amps and 1mm wire.
And a close up of one of them.

Nah, that is what I would use.

Thinking about, the place I got my "training"
welded everything from 1mm to 8mm with 2.4 rods. (and the machines set to "auto balance", and "don't fiddle with it").

When I got my first Tig, probably 15 or more years ago, I bought some 1.6mm 5356 rods, I think I have used about 2 of them in all these years.Thinking about, the place I got my "training"
Mostly I use 2.4 or 3.2.
Thanks
Your postings in this thread certainly helped me decide.
This forum is proving to be a great help, but highlights just how much there is to learn!
