Hello - I've seen aluminium rods for arc stic welders (but never tried them) they are expensive - do they work!? - In my search for bike frames and parts I picked up a few aluminum frames and parts - it would be nice if I could use them other wise I won't be able to weld them.

I just did a quick search for you- here is ChuckE had to say: http://www.youtube.com/watch?v=dIIp3f7xV8g

If the link does not work just search Youtube for Stick Welding Aluminum

If your using the arc welding. Need a DC machine to weld with.

I haven't used them but have work done with them. About 30 years ago a welder at my workplace welded up aluminium suspension struts off a motorcross bike of mine. Raced the bike for 2 years with no failures.

I wouldn't touch that stuff, especialy not on thin material like bikeframes.

If you have a stick dc welder you have the means to tig weld aluminum. Mr. Tig demo tig weld aluminum with dc tig on welding dot com via YouTube. You could attempt to mount a tig torch and scratch start tig welding as Chuckee has demo'd also shown on YouTube. If you really want to try aluminum. Just a thought.

Welding tips and tricks demo'd a Lincoln tombstone with a couple big diodes to form a bridge rectification. They were pretty heavy duty.
Also I believe Charlie_R has converted his ac fluxcore unit to dc using a bridge set up.

From reading any stick welder can become a scratch start tig. It is not eligent or pretty and can be hazardous as the tip is always live when welder is powered on. There is not auto on off gas valve or foot pedal to adjust the amperage. It it all manual. But it can be done.
This is not an endorsement to go out and scratch tig. Do at your own risk. I am only saying it is possible according to what I have read and viewed on YouTube .

some quick links for you to watch on scratch start tig. and Aluminum welding
http://www.youtube.com/watch?v=g72rCd8J9oA- From Chuckee
http://www.youtube.com/watch?v=H_DwA0vzKXI from Mr Tig DC aluminum welding
http://www.youtube.com/watch?v=9lV4tzg4zn0 from Welding tips and tricks - Scratch start tig using a A/C Tombstone welding with DC Bridge recticfier.
http://www.youtube.com/watch?v=XVqBRPVw08Y and just to make it interesting Scratch start Tig welding using a car battery a tig torch and gas. .

There are lots of ways to tig weld- they may not be easy-they may not create professional stack of dime results. But the goal of fusing 2 pieces of metal using the tig method is endless. Just thought i would point out Youtube as an excellent resource for welding knowledge. It is how I taught my self to Mig and learn of the Gas upgrade kit for Gas shield mig welding.
Have fun and be safe with what ever method you decide to use to weld either steel or aluminum.
