Help with 'new' Tig - decode and parts needed

[IainB]

Hi,
New to the forum (someone directed me over here from another - as they said you were all a knowledgable lot )
Anyway, Ive recently purchased this.... totally on a whim and eyes closed and am now thinking....hmmm
Does anyone know what the 4 rotary switches are here? (im guessing the first is Amps, slope (what is that for?!), torch (between arc/tig? though if so - what is the centre position (as shown)) and lastly tig torch or foot switch?

Then the data plate on the back? I2 U2? AC to DC?

Also - can you ID this connector? used for both positive and negative leads?
Believe this to be CP Dix plug?

It did come with a foot control though

The "only" things I need to get is a gas pipe / bottle for the back and a torch/cable for the positive side....which im guessing will prove interesting to track down as a) its old and b)it appears to be from Norway (though I 'think' I may have found an American/UK site that bought out the company)

Firstly can anyone help with any decodes of the above, and secondly, can anyone advise on what torch / leads I need to purchase??

Thanks for any help
Iain

Hi IainB,
Weldequip will probably be able to source parts for you and possibly tell you what some of the rotary switches do.

Happy tigging!

The second dial looks like the slope out
the first is current control the third is to select between MMA and tig
and the last dial appears to be slope in
the centre position is either foot switch or trigger switch
Dc output
Plug is a 35/50 dinse plug Male
Torch needed WP17 Switched and sheathed, with 35/50 dinse adaptor
Need to se the trigger switch connection on the machine we have the torch in stock

Thanks - very much appreciated

the last dial appears to be slope in

that throws my theory out the water then!! if that is the case, what is the significance of the 'sun' (probably the best description!)

the centre position is either foot switch or trigger switch

so - would I be correct in thinking 'T' is foot or trigger and '|' is trigger only?

Torch needed WP17 Switched and sheathed, with 35/50 dinse adaptor
Need to se the trigger switch connection on the machine we have the torch in stock

Stupid question time.....what would the trigger switch connection look like? Im assuming this isnt the 35/50 connector? The only other connection on the front (apart from the negative and 2 connectors that the foot switch is connected too, is the gas outlet).
Actually, thinking about this, why do I need the torch to be switched, if im using the foot controls? (probably a really 'normal' answer to this, but hey, if I dont ask I wont know!)

Also - and another stupid question, is the gas outlet a negative connection, from looking on (I believe) your site, the positive connection lead looks small gauge?

Thanks for your help - much appreciated

Just popped out to the garage to get these

This is the front panel connectors, the top 2 are what the foot controls have been plugged into.

Ive also seen a bit of writing on the main + and - connections, its faint but looks like 'dinse dix bem25'. Outside diameter on the male connector is 9mm

The female gas outlet appears to be 14.3/14.4mm inside, with the male being 15.78mm - it already comes with what appears to be a step down (though this looks a bit worn, thread wise! Outside diam on step down looks like 12mm

Rear of machine along has the gas inlet, this looks like 13mm?

 

[IainB]

Anyone able to give any additional advice on the above please?
Even better if you have a wesbite / ebay store as I have money here burning a hole in my pocket and I really, really, really want to try out this welder!
Cheers
Iain

I have the torch, dinse adaptor and all other items in stock send me a private message and we can sort

Mike,
Any luck with sourcing these bits? (especially the torch, un-sheathed/switched as I will be using the foot pedal)

Also - is the torch connection, screwed onto the gas outlet, also the negative connection, or is there a seperate lead required to go to the negative?

Cheers
Iain

Firstly can anyone help with any decodes of the above

Do you need any info on decoding the rating plate?

 

[IainB]

Do you need any info on decoding the rating plate?

Any info is good info for me - that would be much appreciated
Cheers

The top two plugs are, the one on the left is for the footswitch the one on the right is for the trigger switch on the torch, you need a dinse adaptor so you can screw your tig torch to the power connection the gas connection comes from the dinse adaptor pm me again and I will price it up for you, the problem is there is no cheap way to do this properly

Ok, starting at the bottom:

Input is single phase, 50 or 60Hz. Input voltage (U1) is 220V. Input current (I1) depends on current setting (more on that in a minute).

The case is IP23 rated.

It is a constant current power source (that little graph plots volts against amps), for arc and for Tig.

Output range is 5A @ 20V to 130A @ 25V.

Output is unsmoothed DC, open circuit voltage (OCV) is 60V.

Now for that little table. U2 is OCV, I2 is current, X is duty cycle.

At 60A, OCV is 22V, 100% duty cycle (i.e., continuous). By implication, any setting below 60A will also be 100% duty cycle.

At 75A, OCV is 23V, 60% duty cycle.

At 130A, OCV is 25V, 20% duty cycle.

Hope that helps.
