Oerlikon DTG201

[Feanor]

I've very recently acquired this machine but have no manual or any technical information for it. The machine is a 200 amp DC TIG welder.

However, the square wave markings on the machine front panel - what do they represent? There's also a toggle switch to choose between square wave form, continuous or spot (I presume - it depicts square wave, a continuous line and dots), so again, what does the square wave selection represent?

Here's a picture of the front panel:

Mine is identical except for the 3rd control dial (from the left) on the top row. Instead of a dial, mine has a steel 3-way toggle switch to make selections as described above (Square, straight line, dots).

Where the dial in the picture shows that the left positions seem to be a choice of 3, mine is simply a set position for square wave. Otherwise my other 2 positions for the switch are continuous line and dots (same as this picture - those selections shown to the right)

What does the very first dial (top left) control?
The 2nd dial suggests the frequency of the square wave form?
The 3rd dial (mine a toggle switch as above) seems to select type of arc?
The 4th Dial is a timer and seems to relate to the spot function on the 3-way switch?

The next row of dials (shown red) - what do they control exactly?

The next row of dials (should all be yellow) are pre-gas, slope up, slope down and post-gas. Am I correct?

Finally the 3 toggle switches I understand are for 2TIG/4TIG; TIG or MMA and the final switch for on/off remote or pedal connection.

Thanks a lot for any help/advice anyone can give.

I think that square wave is to represent pulse TIG?

Is the top left knob to control the ratio of high to low current?

I'm sorry but I can't quite read the dial markings on the next row but they look like 0-100% - is it to do with setting the level of the low pulse as a percentage of the high current?

If you had a fiddle I would have thought some of them would be self-evident? Alternatively, someone who has one may be along in a bit?

No help with your queery but when I need a WIG repairing I'll know where to come to

Thanks Graham. Yes, I need to spend some time (it's a rare commodity) having a 'play' with the settings to work some of it out. Pulse though - I suspected as much - good stuff then.

The 2nd row of dials (number 1, 2 and 4) are percentage values from 0 to 100. The 3rd dial on this row is 0 - 200 which is surely the Amps.

I will twiddle about and work it out, but I am hoping someone may come along and save me some time and a good few rods. Having said that, practice never hurts and it's not as often I use two hands these days as gas welding has been relegated to a fringe activity somewhat.

Thanks again though.

Ha yeah. I googled the machine name and the only result it came up with was a 'for sale' site which also contained a few pictures (of which the above is one). Alas the site was German and besides, the advert is now obsolete as it's from 2008 I think. Most of the text was in German, though there was a trace of English somewhere on the page. The only thing I can think is that it's a typo or ............ do they call them WIGs in Germany instead of TIGs?

Hmm maybe. Wasn't Tungsten originally known as Wolfram and might not the word be retained in German? Wolfram Inert Gas - it sounds a lot better in fact.

Top left looks like pulse on time (% on duty cycle), next to the right is pulses per second.

Thanks Shenion, sounds reasonable. I'll be having a tootle with it later.

160A at 100% duty cycle - nice!

Hi Feanor,
Have you had any luck obtaining user manuals etc for your welder? I have aquired a similar (same) machine and I am in exactly the same position as you were: looking for user manuals.
Any help will be greatly appreciated
