Aluminium tig guide getting started.

Switch 14 off. No pulse. Keep it simple.

This is what I am saying,
If you read Richards post,
Please verify what has been said/written/instructed.

Or :-

Is my Tig Welder set up/laid out, with a button missing !!!!
The Frequency Setting is an important part of the process I would assume.

Your machine is fixed frequency at 60hz when in ac mode, you can’t adjust this setting.

Oh !!
Is that normal for this sort of machine,
Or have I bought a piece of crap.
Thank you for the update lol

AC Frequency is often adjustable nowadays but it is really no big deal if it is not. I used TIG for many a year with 50Hz frequency and still I prefer a lower frequency, usually no more than 70Hz.

As Daleyd says

It's not as important as you think. It's a shame your machine doesn't have it, but all older AC/DC TIG sets used to be fixed at 50/60hz and the quality and precision that skilled welders could get out of them was amazing... it's more skill than machine.

No idea if its a good machine or not, but Jasic in general are OK I think?

I wouldn't get too hung up on not being able to adjust it, I imagine they picked that figure for a reason and for doing stuff at home it'll probably be just fine. If anything, for someone new to welding it's one less thing to worry about whether you have it adjusted correctly...

As above: fixed frequency.

I have the manual etc.
Though I hadn't noticed that it is fixed frequency on AC
That is why I posted this.
But concerning The Manual, I have already emailed/spoken with Jasic concerning Their Manual, we have an ongoing correspondence concerning mistakes in it, some have have already been edited, but there are more that I have not messaged them about yet.
Thanks for now
Speak later,
I'm off out trail riding today, hopefully come back in one piece

What current and Hz would you suggest for joining 6mm round bar, butt and fillets?

 

[indy4x]

Had a bash at some Ali TIG welding last night, 1st time using my welder, previous exposure was at college using their kit.

Results were less than impressive but reading @Richard. posts on this I think I know where I'm going wrong with the settings, just need some more bench time

A learning day for me I have some old 2mm Ali to weld in some new Ali I have an old BOC ADR welder on no 2 up to 65A it will get the joint to melt and flow but my weld is to fat I would like it neater and a smaller fillet yes I do cock up but learning what size of rod I have 2 mm on the shelf also what tungsten and shield to try and get it all neater is to dam ugly a weld so far I am better at gas welding it but I want to improve my tig welding and today is the day.

As I am working with old Ali my prep is a s/steel wire brush still have a bulky weld been trying what I have read on here all ten pages LOL.

Just welded some a 60mm scrap angle to make linbin type rack 3 tiers. The results aren't pretty... The goodish, The bad and The horrendous but penetration is ok. Only single sided weld. The external corners were beautiful without filler. The rest look like the Rockies, but still good pentration. 120 amps 40% cleaning 60hz (very dirty ali) cleaned only where needed. Using new Sherman....the arc is loud.

You can't weld ali without filler, it will crack.

Some aluminium you can. Some 1xxx and 5xxx series can be welded autogenously or with identical filler i.e. you can cut base metal and use it directly as the filler.

Many grades of aluminium become crack sensitive due to the proportion of alloying elements which come out of solution.
Most commonly magnesium and silicon, on cooling that combine to form Mg2Si.

I do these in work with no filler it depends on use adding filler slows the process down, material used to be 2mm but I made things harder for myself by agreeing to do it in 1.5, I'd prefer to have burn through but it is not wanted, any dirt on the edge that your welding and you end up with a hole these parts get powder coated,

I have seen that on youtube videos. No cracking apparent. The ali is 6mm x 60mm angle of unknown properties. Probably was part of a carport or similar. For this job it was good enough. No issues. The angle was cut 45 at deg. So the corners were knife edges which fused back to form a nice bead.

From what I've read and experienced you're a little short on amps for Ali. It drags the heat away. At 120A I've found once I've got puddle going it's a race to finish (haven't got foot pedal). Don't like the pulse option, prefer to pulse manually. Also gone to pyrex stubby lens and 2.4mm 1.5% Lathanated (video he recommends 2.5%), The clear cup is a major improvement and the lens saves gas (£65 10ltrs) I've been TIG welding for about 20yrs and MIG for 30yrs, but ali is a different beast. Gas welding 50yrs back. All DIY use. First AC set for me. I use the https://www.ebay.co.uk/itm/202472264757 for cleaning surfaces, doesn't clog.
This is a brilliant channel....

Good article. One thing I was aware of is 'hot shortness' which weldintipsandtricks discusses.
Problem with unknown compositions is it's a case of 'suck it and see' Don't have access to an xrayflourescope anymore.
