2- 30 years experience
and how do you check your root penetration
1- depends on the flavour
2- 30 years experience
we are talking welding here I hope
That's a bit personal aint it? 
was a puller, now a pusher
Im a pusher and I like to see little lumps on the rear.
i'm a pusher primarily and it depends if i can see the back or not. if not, i turn it up, hit and hope

Wadders- why doesn't your girlie move anymore
I tend to push weld these days although I used to pull when I first started. I feel that pushing gives me better visibility of the weld pool and I
understand you tend to get better penetration.
As someone else stated above, I look for signs of the weld dripping through the other side of the piece. If I can't see the other side then I
just judge from the shape of the weld on the top side. With experience, you can tell if it is sitting on the surface or if it is emerging through the
surface. You can also tell from the build up of weld pool relative to wire speed. If the weld pool builds up too quickly compared to the wire speed it
feels like you are getting pushed away from the surface but if the penetration is good then the wire will be absorbed without s much build up. Not
sure if I'm explaining that very well but it makes sense to me... ;-)
If in doubt then practice on scrap metal and saw it in half to check penetration.

It's because the image is to tall, and the new auto-resizer can't cope with animations.

Love it !!
which ever creates the nicest weld on the job at hand. I refuse to conform that one is always better than the other.
push .
i like a bit of spray transfer aswell.
You don't get proper gas coverage pulling, and I've heard it can also affect your eyesight
Used to pull, now push with MIG. Mainly due to pushing with TIG to get decent heat into the workpiece.
I do both very quickly, depending on how good looking she is....

Completely distracted by that ^^^ now! My posting in the alternative universe thread...my SVQ training... was always to push for better penetration.
Pulling is more akin to welding art than welding. Do one test piece of each, cut them and see how good they look.
Back to the dancing girl! Arrr~!
completely distracted too, for got about that wadders!
As for push/pull, do both, with both tig and mig!
Big stuff, heavy work, high power, always push.
Thin stuff, low power, pull.
tig, bit of both, pushing looks neater, pulling sometimes easier and probably better penetration, never been sure with tig though, kinda debatable
what the difference is too!
I have had my whole welding technique turned on its head.
Dave and I are doing a welding course to get the tig up and running. The course also has mig so we are taking the time to learn the correct ways to
achieve good welds and avoid the pitfalls.
Spray transfer is just fab....
We have been doing the roots and caps as well as spray transfer...
With the new style my welds are really stacking the dimes in a very controlled and repeatable way. Would suggest anyone who has never welded before
get a course as you get to use their gas and machines to learn on.

You'll be buying a copy of "A C Davies" next.
Enjoy your course. Knowledge lasts a life time.

Hi Mango'
On the subject of the book, just looked it up on Amazon.
The Science and Practice of Welding. A C Davis. 4 used from £1.47
Mine was £4/19/11
As for the TIG, it's not earning money stuck under a tarp at the back of the workshop is it.
I have a mate, runs a "one man band" car workshop who allocates an hour a day to work on his old cars.
Works on customers stuff till 5.30pm, stops till 6.30 to do his own. It works for him.
My advice is take a couple of hours a week, an evening or a Sunday morning and just practice with the TIG.
If you can get help and advice from your course instructor then so much the better.
You know it will pay dividends in the end.
All the best,
Paul G
practise makes a huge difference. its amazing how you go from being clumsy and non-flowing with the tig to it feeling like an arm extension. I never
thought it would get like that, but now it has.
earning money....what's that lol
