I can afford more expensive machine, but as a hobbyist welder i cannot justify to myself buying more expensive machine

Hi Martl, Stahlwerk is made by china for GERMAN company ....bag of sh*t and i know because i got one of them with plasma as if on picture .Im using as step when i need to get somethig down of shelf .You need to stick with WP26 . iI try micro torche and all dif size and i had probs as you . On your ...

ok, that seams to rule that out. we have seen issues with cheap gas lens and the gas ports have been undersized. a possibility thats the case with the torch. maybe it forces gas through at higher velocity. but i would think the gas lens would settle things down. i presume you are fitting the torch ...

Did some more pressure testing on torch, about 2,5bar it started to leak between cup and cup insulator, not much but still a leak. Changed the cup and cup insulator, this time it held almost 3.3bar of pressure without any leaks.

one other thing, whats the tungsten like? is it getting oxidized? Tungsten remains it's original colour, no color change. Tungsten tip is balled as it should be. this is what makes me head scratch a bit. if its an oxidation issue i would expect tungsten to get oxidized as well. but it sounds like i...

I might be wrong, but the weld looks to me like the A/C Balance is out of wack.... aka backwards. Bottom right knob (in pic)..... currently set to ~70% suggesting about 70% cleaning action or DCEP=70% DCEN=30%. I'd suggest flip / flop the knob to 30% or DCEP=30% DCEN=70% and continue troubleshootin...

Good thought, or, maybe this....How many amps are you putting through that 1/16th tungsten? And what size is the tungsten in your other torch and how many amps are you putting through the other torch? hat size tungsten is only good to about 100 amps before the tungsten itself will start to breakdow...

well a thought from way out in crazy land, you have 1/16 tungsten which i take your welding some really thin aluminium. whats the backside like? your not melting right through and sucking crap back? i have absolutely no idea how that could happen with different torches. tho the weld pic suggest its...

btw what brand is that torch? it looks like a CK. is it a good brand or some knock off? all i can suggest is check each bit. from the hose connection at the machine, to the connections in the body and the sealing o rings on the swivel. make sure all gas port are clean. noting like a bit of crud plu...

Everything on the torch has been tested on the working torch.
Gas lens is clean i even cleaned it with acetone.
Tungsten is 1/16" so is the gas lens and collet.
I have tried it with standard consumables result is the same.

And this is the disappointing result those numbers after those passes are gas flow l/min. I did those passes without filler.

This is the machine setup, upper row first knob is gas pre flow(set to approximately 0,5s), lower row fifth knob is gas post flow(set to approximately 5s), lower row sixth and seventh knobs are AC frequency and cleaning effect. Gas flow from the regulator is set to 17cfh.

Torch cup and cap fits really snugly, i pressurised the hose with the cup end sealed and did not find any leaks

So this is the torch that is giving me headache.
I agree, outside air draw in could be the issue, but don't understand from where it could draw it in.

Gas is flowing without any issues i have tried adjusting the gas regulator, and the result is same, only difference is when the gas flow is really low. It is 17 torch without gas valve. I have tried different collets, lenses, cups even different size electrodes.
I will try to post pictures tomorrow.

Firstly sorry for my bad English, as it is not my native language :D . I am having issues with weld puddle, with flexlock torch and silicone hose(WP17) the weld puddle is like a volcano, it seems almost as the base metal is boiling. Now when i change the torch to a standard torch(WP26) that came wit...
