Argon Flow Rate Conversion on Tig Calculator

[geezer]

Hi Buggy Chief,,,if you have a regulator marked in litres you are a head of the game,,,cause working in CFH and trying to remember those settings is a PITA, working in litres is so much simpler,,,,first of all you must know your cup size,,,it just so happens that the cup size and the litre settings are nearly the same.

For example a number 3 cup would be 3 litres, and a 4 would be 4 litres,,,,,this varies somewhat as the amperage increases,,,however as a good rule of thumb you can say,,,,that litres = cup size + 1 up to 200 amps and then litres = cup size + 2 up to 250 amps. (the limit of most single phase tig welders)

You can check this out by downloading the CK Worldwide tech manual and looking at the chart on the bottom of page 3

Hope this helps answer your questions.........Knowing your cup size and using the proper electrode size for the amps is the key, setting the gas flow in litres is then easy.

Excellent information as usual geezer. Thanks. How does the rule work for gas lens setups?

Thanks Turmond,,,always glad to help if I can,,, As far as using a gas lens goes,,,according to the chart on page 3 the rule of thumb would approximate cup size less 1,,,and cup size less 2 in the 200 amp+ range,,,due to the increased efficiency of the lens,,,check out the chart on page 3 and it will give you a rough correlation for that...I find it much easier to remmeber simple rules of thumb and then adjust from there...

Just when I was about ready to get a piece of tape to make an alternate scale, you come along with a much more elegant solution.

Are lenses better than cups for some applications or in general?

The advantage I see with a lens over a cup is electrode stick out to reach into tight areas, the lens gives a more directed gas flow, some people try and cheat by using a small cup to get into the tight areas,,, all that does it overheat the cup and the electrode...so yes a lens would seem the way to go but it costs more like everything else that's good. Of course that is stated on page 5 of the CKworld wide tech manual,,,,good reading ,,,see my previous posts to link to it.

Hey Geezer-

Thanks for the helpful tips to a Newbie.

The price of a regular gas lens is nothing considering how long they last $9 for a five pack http://www.ebay.com/itm/5-45V43-1-16...item2eb270ea09 and $5 for a ten pack of cups http://www.ebay.com/itm/10-53N59-5-a...item2c5624f9e6

Tip: if you don't want to buy a bunch of different size gas lenses, just buy one pack of the smallest size you'll use and drill them larger as needed.
