Sherman Tig (Jasic in disguise?)

[DavidL]

Update - you're in luck, I had already taken some photos!

You can see the switch (nearest the cable entry), the ranging (rotary) pot (middle), and the pedal (linear) pot (further from cable entry). I think you can make out the colours from these two photos.




I'll try and find a picture of the plug as shipped for reference...

Sorry to bombard posts (I should've edited!)

Here's the plug as supplied - as memory serves, it's upside down in this photo, so the disconnected wire is actually the red pot wire.
The yellow/red you can see connected are the "torch switch" pins
The green and (obscured) white are the other 2 pot wires.


And here's a different close-up of the linear (pedal) pot and ranging (rotary) pot - taken alongside the previous post, just to help you see the wire colours (wasn't exactly too clear top down).


Right, I'll leave it there to stop spamming

So there seems to be more than 5 cores? Any chance you can send a photo of how you have modded it when you get a chance please?

Only 5 cores needed, the Jasic manual shows the wiring needed, the torch trigger in the pic would actually be the microswitch in the pedal.

Sorry - my photos are a bit confusing. There are only 5 cores going to the sherman, like in Hood's diagram.

The two pots are wired together in the pedal to make a sensitivity/range-adjustable pot (a bit like the diagram here - different colours labelled though - https://electronics.stackexchange.com/questions/105519/potentiometer-puzzle-tig-pedal ) - and that can stay "as is".

so to translate that diagram from stack exchange --> my photos

• black ==> green (3c cable, to rotary pot only on my photo)
• red ==> white (3c cable, to rotary pot and also internally wired to linear pot in black in my pedal - you can perhaps see black/white wired to pin 1 on the rotary pot in my photos)
• yellow ==> red (3c cable - the middle wiper pin on linear pot and the one that had come off at the other end in the plug!)

To mess with you (where you're seeing the extra cores) inside the pedal there's also:
-a yellow wire connecting wiper/pin 2 of the rotary pot to one end of the linear pot
-a black wire connecting pin 1 of the rotary pot (also the white wire) to the other end of the linear pot
(both marked with red crosses in the annotated photo below)



You can leave them as they are. It's only the white, green, and red wires you want from the pedal on that 3 core.

The red and yellow (2 core) go to the "torch switch" pins
[EDITED to try to clarify colours from my photos and the stackoverflow diagram]

No chance of that, painting is one thing I excel at being terrible at

I seem to remember you saying that before.

 

[Slowcoach]

Well, it was like this.
I sort of got one too.
I went for the 201, no pulse (bit like me) but I’ll see how it goes.
Ill get some gas this week and a regulator hopefully.

Right I think I’ve got it... wait out for further help posts in the coming weeks!

Looks very similar to the Eastwood tig sold by frost. If I remember correctly.

No worries - give us a shout

I went back and edited my post just to add another photo of the pedal marked up to show the internal wiring. It might help or hinder, but feel free to have a look

Maybe it is mentioned somewhere in these 26 pages but the dimensions of the Sherman and the Jasic in the OP differ isn't it?
Jasic 200 Pro Mini TIG 200 Pulse AC/DC Mini Inverter Welder Dimensions (LxWxH mm) 435 x 160 x 340 9kg
Sherman Digitig 206P AC DC Dimensions (length / width / height): 40cm / 13.5cm / 25cm 8kg

Seems to me the AC/DC Sherman is buildt into the smaller case of the DC-only Jasic's?

 

[Hood]

I just measured mine and it is more like the Jasic sizes you mention so likely Sherman just listed them incorrectly.

 

[Robbie260]

Dam you guys you are seriously tempting me and i have only just bought a lorch micor tig. But this would expand my abilities too the full range as the lorch dosent have ac tig and its quite justifyable for the little aluminium ill do at £500 unlike most ac/dc tigs plus means i could use it for some of the crappier jobs if needed instead of the lorch.

Jasic acdc 200amp v sherman acdc 200amp
Both maxed out my 10kg scales with torch and lead on. So weight is similar

 

[DavidL]

The (nearly invacar) blue and the (presumably gold-encrusted?) orange really look nice together

The Jasic rubberised bits do look a lot better, tbf. I might try to plastidip the front and back

To be fair it's probably the light more than difference.

just being cheeky, but it reminds me of this

It's ok we will go get the bigger meter.

Is their website down ??

 

[Pigeon_Droppings2]

Yea the site went down a few days ago...wonder if they got a call from Jasic
