Does my Tig need to see the Tig Doctor?

Any good pics? I am like some kind of sadistic torturer to the poor things

Sicko!

you need to cut that tungsten back an inch, its really contaminated, 10LPM of gas is probably, and i say probably depending on your setup, too high. As said before post flow, i usually have around 5-6 seconds, you want it to flow until your tungsten has cooled.

To be fair a 1.0mm tungsten will cool very fast, but without seeing the setup it sounds like they are being cooked a bit hard.

I do believe he mentioned above he is using a 1.6mm tungsten? Tungsten quality certainly comes into how well they handle higher amperages though. My HFT Blue Tips still work at 125amp AC

 

[Jim Davey]

He also said he used 1.0mm

No I photographed the wrong pkg.. My fault .. I have the 1.0mm electrodes but I've hardly ever used them.. What would guys recommend for gas ltrs per min then.. Tbh I seem to read and hear all kinds of ratios to metal thickness to tungsten size etc etc ... I've even tried to use the tig guide settings on the forums beginners guide... Getting a little confused more than normal lol.. So too high gas flow is bad too yes.. But I need longer post flow yes...

5lpm covers most things. Post a picture of how you would normally have your torch setup. You may be extending the tungsten a little too far etc. What size cup are you using? WP9 or 17/26?

IMHO 1mm tungstens are of no use to me. A 1.6 happily controls 5 amps if I need it to. The key is how you prep and how you look after that prep. I too see people welding with tungstens looking a mess and its criminal. The arc is all over and welding is a nightmare.
By a soft wheel noods I mean a soft stone bench wheel. Mine is a green wheel 100 grit and it is very soft but it cuts through tungsten so well with no pressure required so it grinds cool.

Ok mTe I will order one of those now... I always try to set my torch up as very best I can, the tip of the electrode is always set as short as I can get away with but obv with angles etc I then have to set it to get into the angle! As soon as that's done I revert back.. I normally grind a sharpe point like pin sharpe, I wipe the work and electrode with acetone.. Then I use the lowest setting of amps I can just enough to get a puddle and get it moving nicely.. Oh and after sharpening I run a very fine sandpaper along the length of the electrode till it's nice and clean and then use the acetone ..

Normally a 9 mTe ...

This good enough for you?
This was a new gas lens and cup. As soon the puddle formed it just exploded, more spatter than a mig.
It was stated to follow DIN standard but I can swear it was cast iron.

 

[Jim Davey]

You need to sand of the zinc plating first.

 

[AndersK]

Did take most of it off, I can assure this was nothing like welding on zinc

 

[eSCHEn]

Nowt that a bit of working over with some pliers and a bastard file won't fix.

They love it rough.

 

[Jim Davey]

Nasty bit of porosity then, it happens from time to time.

 

[Richard.]

Never use my lenses on stuff like that. Any thing with a coating or galv or manky casting etc out come the collet bodies. My lenses are not consumable.

 

[Brad93]

I've got a cheapo parweld lens that would be used on anything slightly dirty it I needed the coverage. No way I putting my CK lenses near anything but clean new material.

But it was just one of those just- gonna-do-this-little-quick...
