quite true for sure. I teach welding for a living, so keeping up with AWS and ASME standards is a part of my day to day life. If your not at least somewhat immersed in it, it would be hard to.

All that aside, for garage use, in the USA, those would be the "have in the shop" standard for me imho... but you are quite right, none of that does much to help ryan over in Germany, and for that I apologize.

Also Ryan, one thing I can say is Yes, Pure argon will do you just fine. Bottle size matters not, just changes how often it will need refilled obviously.

Also, I am a teacher, so I am biased, but if you are able, I really feel that a short term welding class would really set you on the right path. Get started with good habits and techniques vs. bad ones.

For example, where I teach, I have a 5 night, 20 hour "intro to welding" course that costs about $189.

 We don't tig weld in that particular class(mig, stick and oxy acetylene safety and cutting), but it would still help you get a few fundamentals.
Böhler emk6 should be available for all round mild steel welding where ryan is located, and yes, you really need good teachers for welding to become easy and fun!
Also, it was noted earlier that there are no "stock" alloy fillers, thats because you need a filler very close to the original alloy content, also the two most common cast alloys are AlSi(silicon alloy) and AlMg(magnesium alloy). You basically need to find a filler with the same percentage and type of alloy to get a good result. And be able to tune polarity after conditions, too much positive charge on the electrode and it can break down and embed in the weld joint, where you dont want electrode contamination. Yes, all this takes a bit of schooling, for sure.

So guys I finally ordered my welder!

Its a 200amp tig welder!I also ordered wlding stick for ally, stainless and mild steel, can´t wait to set it up!
I also have an idea for a welding table,here´s a pic of the table the guy had that held the "welding lecture".  8)

Is there a certain grid these holes have on these welding tables or is this random?
I will get a thick steel plate waterjet cut and would like to have the grid and hole dimension to start to draw it in CAD :-)

In school we used to have one tapped in M8 in a 10x10cm (roughly 4"x4") pattern, so you could bolt stuff down.

I actually like his setup VERY MUCH. I may have to copy that down the road...

Jep its amazing isnt it?
I will start with a thick steel plate like he has on the top and will build that cart down the line too, when I can throw on good welds.
Really nice when you just need a power plug and can weld anywhere in the workshop...

Err well, no I meant his idea, that his cart is the welding table at the same time. That's quite a bit unusual.

So guys I finally got around to bring my gas bottles (CO2 for my stick and Argon for my new TIG) to the gas bottle firm and now I need to wait for 2 weeks... ???
I´m in the process of planning out my welding table and I have a few questions for you:

As for the thickness, I heard the thicker the better (warping)...NO JOKES guys :-)!
Would 1,5 cm do it?

Which size of table would you advise?

Is there a certain hole dimension welding tables should have?

started out with a 100x100cm table with 2cm thickness but that dang thing would weigh 150kg´s...so I need to go smaller...

thanks!

Hope there was just something lost in translation there, but you don't need Co2 (or any) shielding gas for stick welding.

For the table, yes the thicker the better for several reasons, mainly being rigidity, but id take a thinner flat table over a thick bowed one any day.

The other thing when deciding on the size (and even thickness) of a table is moving it. How long will you be in your shop, and when its time to leave, will you need a fork lift ect. to get it back out?

These are pricey, but I really like the design. They laser cut the pieces and then ship them to you. May be good inspiration none the less.

Not really any set dimensions, just whatever your preference is on size.
Mine's just a 8' x 3' piece of 1/2" plate with legs, no holes. I've got my bench grinder, some fixtures, a vice and a drill press mounted to it. Stationary obviously.
