Welding Tips and Tricks

Hey Guys,

New to the forum here. Over this past summer I have been successful in getting my CWB (all positions), 6010 root/7018 fill and cap, and just passed my 7018 all the way a couple weeks ago.

I have started working on Tig and seem to be picking up the basics pretty quickly. I am just trying to find out what peoples settings are at when they go to run their root pass on the 6g test.

Where I am practicing these are the specs for fit up and equipment used:
Gap - tight 1/8
No landing
1/8 tungsten
1/8 filler wire
Lincoln Electric Invertec V350
105 amps
Lay wire technique with a slight weave just to the edges, traveling fairly fast to not create a keyhole.

Just looking for other ideas to fool around with to see what is best for me.

Hey mate. Welcome to the page. Jody, the founder of the show, just this week released a new video showing ways doing exactly what you are talking about. On you tube and also this site.

Weldin Mike,

Thanks for the info. Looked up his videos and the only thing missing which is my concern is the size of tungsten he is using with those amps. I am not sure if it makes a difference or not.

Smittie,

The data you posted SAYS 1/8" tungsten.

That weld can be done with 1/16", if you know what you're doing, but if 1/8" is called, that's what you should use.

I can do any weld that calls for a 1/16 using a 1/8... it's all in the grind. You can make a huge tungsten come to a fine point, but you can't make a skinny tunsgten fatter to take heat.

As long as you don't exceed the power rating for the tungsten, any size will do.

We use 2.4mm for everything these days. Upto 180ampx.
