lol smells like a spam bot (seeing as he has the brand name he mentioned in his nick), but oddly its on topic and in the right section. haha has me second guessing. My guess is its a way to get Google search results hits when someone searches for "welding aluminium with a mig".

but back on topic, I'm thinking of buying a MIG, but wanna be able to do aluminium welds too. do I have to get one that's capable of really low voltages as the aluminium I wanna weld is pretty thin?

Shan, same smell i got from it haha - the thing that gave it away most was the automated template used, that worked on the other thread in the US

Alloy welding requires more amps than mild steel, but as VB- stated nylon liner is best practice along with the correct gas shield- depending on the mig you get, you could get a spool gun for it that holds the roll on the gun to stop binding in the gun.

so what are YOU doing on a US based Z forum craved? good tech/fab sections on there or anything?

can you still get those push-pull guns? havent really seen em around (bar the ancient ones floatin round the shop/at trade school)

I can weld down to 1mm fillet and butt welds at work, but that is on WIA 450 industrial machines with a 'softarc' setting. But that setting my only be an Incat program.

At home, I have a WIA 175 which I weld mild and ally with. Coiled steel liner for steel, nylon for ally. Use .9mm or 1.0mm ally wire with Argon gas, no mixes, just Argon.

Did I mention my trade is Aluminium welder / fabricator?? *lol*

Cheers, Greg.

as above!! use pure argon and nylon liner. the liners usually dont last that long tho

i welded heaps of alum with mig but nuthin under 4mm plate

i would say a mig weld that thin would sit on top of the metal more than a tig weld which tends to "sink in"

that was my experience. btw i was using .9 and it welded 4mm up just fine

was on a unimig 165.

how do you go welding steel with pure argon ive never tryed it but from what ive herd it doesnt penetrate really good if it works well i would love to no as ive got a mig and i just bought a tig and really dont want to have 2 bottles

thanks tim

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      Yeah, but knowledge of one wire's insulation worn through to short on earth implies the possibility of other wires doing the same. I had my power steering die, because the wire that runs to the solenoid valve on the rack runs in the same loom as the power wire for the O2 sensor. And when the O2 sensor/wire did something stupid and burnt part of that loom to death, the only indication was the shit(ter) fuel economy and the heavy steering. It took deep excavation of the looms in the bay to find the problem. Not wear through in that case, but similar shit.

      Ah, I thought he'd wired it to one of the spare ECU inputs! Too long ago since I read that post, ha ha. I've been arguing with radiators, harmonic balancers, alternators and rust since reading it.

      Correct. The ECU cannot read oil temp. (Well, I think it probably can in some situations. I did have the thought of potentially repinning the ECU when I was doing oil pressure). I am using this into the MPVI dongle, so that the MPVI dongle can read oil temperature. It is attached to a VDO gauge which is obviously calibrated to whatever curve the sender actually is using. This would be easy if I could setup a table of voltage to temperature like many sensors, but it appears I cannot do this and can only setup the transform rule which appears to be Input (voltage) x Multiplier, and add an offset. This to me means it MUST be linear. So it may be a complete waste of time wiring this into the ECU. The idea was that the MPVI3 has standalone logging. I wanted to use this instead of a laptop with serial cable (for wideband) for long datalogs. Given the wideband also has electric interference, I may never trust this either in a world where the serial wideband and the analog output wideband do not agree. Last time I did a trace I could see the two wideband traces follow each other, but one was a little leaner than the other. I plan on playing with voltage offsets and actually driving the thing to see how close they correlate. If they never correlate... then, well, maybe I'll never use either. Ideally I'd like to have the Analog wideband read ever so slightly leaner than the serial one, because the serial one is 'correct'. Tuning the car to be ever so slightly too-rich would be the aim. Not needing to have a laptop flying around in the footwell connected with cables is... an advantage. About the only one from the forced upgrade to MPVI3.

      Hopefully not, since he knows the fuses work ha ha ha

      I don't think he's got it on a gauge and on the ECU. I think he's got it on the gauge and on the HPTuners DAq thingo. Remember, we're talking about oil temp here, not something that the ECU is actually interested in for its own sake.
