No aluminium welding?
Hi all,
I am looking to get a new welder to weld up some rusted sheet metal in my S3. I currently have a 30+ yr old Arc welder which I can use, but its not pretty. I have access to a decent mig welder, but I am looking at a little DC tig/arc welder as I like the control you have with tig, and to be honest if I need the speed of a mig I can either borrow my mates or take longer using tig.
I am definitely a hobbyist, and am looking to spend less than $500 on a lift or HF start machine (no scratch start). The two I am eyeing off are the Rossi 200A (its $220 on ebay) and the Cigweld 180A for $299. Both use a 15A circuit, which I have in my shed. The Rossi apparently has HF start at 60% duty cycle, while the Cigweld is 40% duty cycle (for tig) and is lift start. I don't have any radios near my shed so the HF start is preferred as its easier to start on dirtier surfaces. But then the Cigweld has a better reputation and I can get it locally instead of off the interwebs.
Anyway, anyone have any thoughts? Anyone used either of these welders? I think the Rossi comes with more gear, such as the tig torch etc, though I'm not entirely sure, and its probably not the greatest quality, though it will probably serve me just fine.
Cheers,
Dan
PS. I've had a look for second hand welders but there a no decent ones near for under $500. I've also searched the forum for this info but the recent threads I found were for mig or arc.

I just purchased two Power Craft 131......as advised by my boiler makers, 10amp and can burn through 16TC ‘s all day.
We have more expensive caddy’s and there go to is the power craft as 10amp outlets are easier to find in our plants.
We get a pretty good price on them.
Oh we don’t use the TIG function.....
They may be ok for small amounts of use, but you don't get much in the way of quality for that money, and doubtful they'll be any spares to be had in 12 months time but if ot suits your needs. Toxic may have some advice on these cheaper units.
I lashed out a couple of years back on a Lincoln multi process unit and it is brilliant. I do use all the functions on it (when I have the gas) and there isn't many weekends it doesn't get rolled out for something, so worth it for me, but I have no dramas with people choosing cheaper items for infrequent use - you should see my woodworking tools... 😁
My only advice would be if you were buying it for MIG work (which it sounds like you aren't) but if so, go for a unit that takes a full size wire spool and not those little mini reels which are basically useless IMO.

I bought a cigweld 175 after having an old transformer arc and then a mig, i find it great .
Does most stuff quite easily, no gas , only one dial KISS.
I don't plan on it, but apparently you can weld aluminium with DC tig, though not sure how thin. AC is definitely better, but I can't justify an AC/DC unit.
If it was just thicker material I'd just use the stick welder, but as I'll be welding thin steel section up to 4mm steel my understanding is a tig gives you the most control and least blowouts.
That said, the bonnet and floors in the S3 have holes cut by the previous owner(s) which I wouldn't mind patching...

In theory you can weld ali with DC TIG but in reality it’s pretty much impossible. A spool gun on a MIG is a much better option.

That's why I was leaning towards the Cigweld unit - the brand has been around longer and I have a better chance of customer support - the Rossi is likely a throw away item if it fails.
That said, if I get good use out of it, and find good reasons to have a better welder, when they die I can then justify a more expensive setup.
I'm hoping Mitch drops by with some advice though he probably wouldn't go anywhere near either of these machines.
