Stainless is generally sold in Imperial sizes, so too are the fittings .
50.8mm and 38.1mm are the most common sizes, 50.8 is usually but not always the most suitable .

For tigging copper
DC -, Ar or Ar/He gas, thoriated electrodes (Zirconated would be OK also) , nice sharp point.

Hey Grahame,
I use 100% Argon for mig and tig ally and stainless.
Corgon 5/2 for mig and tig steel
50/50 He Ar for 10mm and up ally tig only

100% Ar on mig SS is fine

When you need to use a grinder , use an aluminium grinding disc , they don't load up like the metal grinding discs do.

Will have to remember that acid trick though, thanks for posting that.

Got news for you Dave and its all bad.:doh:
Your steel blades will not last on stainless, you have four options.
a) a cold saw (expensive)
b) a dry band saw (miter accuracy not as good)
c) a wet...

I bought a Maxmig 210i by Liquidarc about 10 years ago.
They are made by Lincoln and it has not skipped a beat

Something like this one ?

Do not expect too much from a cheap band saw , they do their job and are great value but they have limitations...

Maybe I just got the base model...

I've 2 in the factory and personally cant stand them , my son loves them. I found it not real comfortable ,had no sensitivity dial and was a fixed shade at 11 (a bit lean for heavy mig) another draw...

Fair enough, hydraulics is quite out of my realm of experience ...just a thought.
Good luck though

I am not sure of your application or your requirements re ascetics or strength but could it be as simple as welding a nut on? or a nut into a tube and welding the tube on?

No

My vote is Baltic over Cypress, just too clear

Top post.
The sound your hearing is spray transfer.

Yep on ally is hot and fast ,if you do it right

opps

Cheers mate:wink:

Your advice, and the suggestion concerning the wire cup brush on an angle grinder, are very good suggestions for cleaning rust off steelwork in general. I have not used a flap sander for...

I have noticed that also funnily enough. (Sarcasm being the lowest form of wit ...remember?)

Oh bull dust!
With a flap disc or a belt sander you will not hurt it .

Proof:

As a matter of fact I have another bench I weld on regularly and I clean spatter off it with a flap disc.

I would suggest that the medium you use to remove the rust should reflect the future use of the bench. And its size.
No oils if your going to put finished timber or weld on it.
A course grit sand...

Looking at the specs I suspect the 220 is more for you.

200 vs 220

• Duty Cycle: 15% at 190 amps. Vs 25% at 220 amps.
• 8 Fine Welding...

You shouldn't need to .
The 200 CIG should have enough balls the 220 may be a bit better for the extra 300 . I have a 3 phase CIG (Transtig EC250) it has never skipped a beat in 10 years.

I would certainly try a long series drill bit before buying a lathe.

Yes 3mm ally can be migged and successfully.The biggest trouble your going to have is its only 25mm.You have nearly finished the weld by the time you have the heat into it. 38mm box or 50x25 will be...

I have in my hand a small calculator .
It has on the back:

Electronic Calculator

CE 2008
Made in China.

As Grahame said vertical up on 3mm is not ideal . Vertical down IMHO is a last resort.
A tight fit up will help . I do it push at about 15-20° forehand. I also prefer DC. A "Christmas tree" weave...

I use and recommend Lincoln , but I use flux core rarely .

The secondary lines you are seeing are Die lines from the extruding process, not "grain"

Oh I may add!!!!

Is it ally filler your using?

Sounds like a dumb Q but I have on so many occasions picked up some SS filler ....:~

I thought I should have known allowances for tread out of level.
Upon looking it up I can confirm Peter it is 1:50 for landings (3.9.1.3.h.iii.).
But no where the trueness of a tread is mentioned,...

At what stage is your mezzanine?
Can you raise your floor level easily or economically to accommodate the steel staircase?
As mentioned above 44mm does represent a substantial trip hazard.

It is not.



That does not even make sense

Yes, in this case it is measured as the difference in height from the top of one tread to the next.
