Dry lines

[nbyjim]

I am working on a project inside of a house. There are three pipes 18"dia 1/4" thick 90" long. I will be welding them together.Once the pipe is welded,there is going to be a tank 40"dia 5' tall. I plan on doing all the welding using a dry line.I have a Dynasty 300 my question is how long can I weld before I have to stop to let the lines cool off? thank you

Till they get hot .

Dry line

So,five minutes of welding,then let it cool for five minutes? It seems the lines get hot pretty quick.

Are you talking about running a water cooled tig torch without water??

[nbyjim]

Dry lines

No, a gas cooled torch.Thanks

[Desertrider33]

Shouldn't be a problem then, as long as the torch is sized for the current used. When your hand gets hot, take a break.

Yeah I'm wondering what this thing is, considering he said it's going inside the house...

Stick welding inside the house is usually not a great idea.

This Is True

Stick welding inside the house is usually not a great idea.

However, he didn't say if the house was livable, done, under construction/de-struction, etc.........................

This ought to be good

Home brew, or home made something!
