down in the sump :-)

[Steve Kerswell]

My mate bought an alloy sump for his fast pinto, it leaked :-) However help was on hand, we borrowed an AC tig set and I have spent a pleasant afternoon down in his pit welding his sump in position. Pleased to say, I've still got the touch, no more leaks. I have radiation burns on my forearms and neck because I only had a tee shirt and forgot the tig gloves :-(. Smell a bit sumpy oil as well. Plus I'm pretty grimy. All good fun in a kit car builders life.

I was not allow the Tig until I had passed the aluminium welding test by oxy acetylene, as for mig and aluminium yes it's a common practice now, but use a helishied gas, argon is old hat nowadays, much better mixes about. The first 20mm. of aluminium mig is called the false cap, it never welds to a standard. It's to cold and does not mix with the parent metal, always use preheat and a run on plate. The same can be beneficial to steel mig. Cleanliness is important with any weld.

still have a full bottle of pure Argon, and i am trying to find a "spool on gun" torch for my new Mig welder to weld Aluminium. Playing with the TIG was fun but a steep learning curve to get good results and getting the Snap-on mig welder gave me the possibility of Ally and stainless welding using a MIG (my no-gas mig is mild steel only) but as i say getting good consistent results with the TIG would take time and Steve had just knackered his ....so it seemed an ideal solution. He gets a good 160A DC TIG he will use and i can get some parts for the S1 and a spool on gun for the MIG
what set up are you using for Ally welding Adrian?

[Adrian Southgate]

Needed to do a small repair so I had a car for work monday. playing with the white one tomorrow though.

[Adrian Southgate]

I've been MIG welding ally today, can't understand what all the fuss is about as long as the surfaces are absolutely spotless my MIG copes quite well using Argon from a very big bottle.

DC TIG On Aluminium

You tube of a guy who shows you how with a DC TIG.........

[Dave Adams]

argon for an AC TIG welder Helium for a DC TIG welder.......expensive as you need a high gas flow.

[Big Vern]

Argon Dave, not helium.

[Steve Kerswell]

Earnt enough today to pay for it, thank you very much !

[Steve Kerswell]

that makes your voice go squeaky :-)))

[Dave Adams]

that TIG of mine would weld Ally ....so long as yo use pure helium gas apparently....
