It doesn't say here's a picture of the paket it came inHow large. This is the important info as the bigger the cup the higher the flow rate.
In a draft-free environment, I normally run around 15 to 18 lpm to get oxide free welds on Titanium with that kit.
Thanks for that I've tried and it seems a lot better i need to get a new bottle now because my 9 litre one only lasted a week but at nearly twice the flow I don't think that it's going to last longIn a draft-free environment, I normally run around 15 to 18 lpm to get colour free welds on Titanium with that kit.
What are you using a ck gas cup like that for?Thanks for that I've tried and it seems a lot better i need to get a new bottle now because my 9 litre one only lasted a week but at nearly twice the flow I don't think that it's going to last long
Yeah it certainly does. 15lpm on the shroud 3-4lpm on the insideI'm only a hobby welder not a pro but I moved from a 9 litre 200 bar bottle to having two 20 litre 200 bar bottles on hand when I started learning about welding Titanium and Inconel. Back purging and running big cups starts to get expensive fast.
I am wanting to start on some titanium so I wanted to get it worked out first and zinc I was given it as part of my compensation for the cooler I just got that turns up damaged I might as well get the gas flow worked out now as i am of for a 20ltr 300bar bottle next weekWhat are you using a ck gas cup like that for?
Your 9 ltr bottle will wither away in no time using that and it will be a total waste if using it for common metals*
These big lenses and cups are designed for exotics that are completely intolerable to surface oxides. Like bigoz shows above its for metals such as titanium.
* by common metals I refer to steel stainless and aluminium as they are most commonly welded. You don’t need anything bigger than a number 7 ceramic cup for those.
So do II found Ti is a really nice material to weld once you get past the technical issues and expense of both gas and filler. I hope you find the same and enjoy yourself.
Are you a competent tig welder? If your still at the beginning stages don’t waste expensive fillers and materials and gas on trying and practice. That’s just crackers. Get some mild steel sheet or plate and grind it up bright. Practice on that. Titanium is certainly not practice metal unless you have money to burn.I am wanting to start on some titanium so I wanted to get it worked out first and zinc I was given it as part of my compensation for the cooler I just got that turns up damaged I might as well get the gas flow worked out now as i am of for a 20ltr 300bar bottle next week
I think I am competent here is one I done last week in 304 for a rack to holds angle grindersAre you a competent tig welder?

I wasn't wanting to practice with it I was wanting to make some bits for my nitro carsOk well it’s up to you but I personally wouldn’t use titanium as practice material.
When you can get a silver or at most gold coloured weld on 1.6mm stainless you can move on to titanium.
It’s not just about gas coverage, it’s about heat input
