That's usually only a couple of rods in use so they just sit on the top of the welding cart. When I start using a rod I cut it in half else its just too long and unwieldy.

Today was a 200A AC/DC TIG unit install and play day. Only problem was once I got the unit all unpacked I realised I didn't have matching hoses/regulator connectors. Blasted BOC had decided to do stuff just a little too clever so the hoses and connectors for the BOC 175i were all slightly different to this units. Net effect is I had to make a temporary hose joiner while I wait for the proper solution to get delivered next week. So as to not waste my very limited brass I made a mild steel joiner to see me through the weekend. Started out as 10mm round bar 50mm long then got, drilled 3mm all the way through and turned into a joiner for 8mm ID to 6mm ID hoses. Used some screwed hose clamps and this works a treat.

The next pic shows my very first aluminium bead attempts. Below the red line was a bit of a screw up until I read the manual some more and realised that the "clean width" mean the amount of DCEP I had v's DCEN. I had set the % at 65 which actually meant 65% DCEP and that was butchering my tungsten. The last two beads had 35% DCEP set but the amps were still way to high.

I next unplugged the torches switch and moved to the peddle. Wow what a different that made to be able to control what was happening. Even though I can't limit the max amps on the peddle (it varies from 10A to 200A) its still much more dynamic. Given Aluminium is very very sensitive to the heat going in being able to change amps on the fly seems like a must. At least for newbies like me.

Anyway the beads above the line are using the peddle and while not flash are clear improving as I come to grips with the peddle control, dipping the filler into the leading edge of the pool and keeping a steady rhythm. But most of all I'm welding ALUMINIUM!

All in all a good Saturday and starting to extend my welding capabilities beyond mild steel.

Cheers,
J.

Maybe we can make Ali fittings for the printer - we could construct from separate pieces and you could weld them

Yeah in like another 5 years when I might just be starting to get consistent.

I tried making a simple bracket this morning out of 19mm ali square tube with a 1mm wall. I got there but dammit the welds look like a druken snail made them using worm poo. Tungsten too big, torch too big and hard to manoeuvre in my newbies hands, and 1mm wall ali is super super sensitive to the heat going in.

BUT I got there.

I don't know anything about TIG but I thought that on some machines you could set the maximum amps at the peddle. Can you do that?

Not on this unit. Its not that clever. Mind you setting the max amps at the peddle won't help the cause if that is still too hot. It's just practice and the more I do the better I am at getting the control on the peddle.

After some more trials today I think a big chunk of my challenge is that the filler rods I have are way way to thick for the sized joints/material I am working on . I have 3.2mm rods and I need to get some 1.6mm or even thinner stuff.

Cheers,
J.
