Is it possible to weld copper, brass, aluminum or stainless steel
on an ordinary 150 amps electric welder ?
And, if yes,  which elctrodes do you need ?

Thanks, 

Klaas

Hi Klaas,

Stainless steel, yes. Use matching filler, your welding supplier can help.

Aluminium, no, needs TIG or MIG with continuous HF.

Copper. Hmmm. Maybe, the problem is that the weld pool freezes awful quick 
because of the high thermal conductivity. You need lots of power. We managed 
it with MIG. Never tried with a "normal" welder.

good luck

For copper you need TIG, with helium as the shield gas if it is heavy
gauge.  Light gauge copper is easier done with acetylene.

Don't bother even attempting brass, the zinc will boil off and it will
be brass no longer!

Klaas:
Your address seems to indicate that your are in the Netherlands and I am 
in the US:  You have not said what an "ordinary 150 Amp welder" is in the 
Netherlands, AC or DC?  Here in the US, the newer versions of "ordinary 
welder" for home shop or farm is an AC-DC unit while older welders (such 
as mine) are AC only.  Nonetheless, there are electrodes available for 
aluminum can be bought here in the US at most welding supply shops in 2-3 
lb (about 5kg) packages but they are DC only...One manufacturer is 
MG Welding Products, Menomonee Falls, Wisconsin, USA 53051, phone 
414-255-5520  Fax 414-255-5542 (after you dial whatever it takes to get 
the US) check with _your_ supplier of welding equipment to see if you can 
obtain it locally, if not they may have a Euopean version of the same 
stuff.   Copper and Brass are not, to my knowledge, arc weldable without 
spending a _lot_ of money for high-tech equipment; this is best done with 
the torch, and your question specifies "ordinary" equipment, not 
expensive machines...If you need any further info, feel free to e-mail 
me; I have worked minor miracles with "ordinary equipment"..never could 
afford the expensive kind...
