Good day, I'm new to the forum.
Been arc (stick) welding but want to get into tig welding.
The investment into argon bottle and machine can be expensive.

I'm looking at mainly welding stainless and mild steel. But I'm thinking that i might as well get an AC/DC machine if the cost allows.
So that aluminium welding is possible.

Many popular machines are not available in South Africa. Reviews and YouTube videos don't exit on locally available machines.

So, I'm asking for advice if anyone knows of a good but affordable tig machine available in South Africa.

1) DC machine with HF start and pulse
2) AC/DC machine with foot pedal

Regards
Bob

Hi Vostro,
I cannot honestly say that I have never checked out whats available in RSA, but I know Unimig and WIA/ miller are available in Aus Nz. Can recommend them well. if you are buying new.
I dont know what your budget is but personally if you are keeping costs low to start, try this.
get a 17 torch set with a valve to suit your stick welder, 1.6mm or 2.4 mm Lanth gold. whatever amps your stick welder will run, use that size material. find scrap. Gas lens and insulator.....dont forget the different insulators. you will be going back for a 2 buck part or leaving a gas lens on the bench til the next trip to tool store. and of course gas. that is you in the ball game. a good way to grind tungstens is nice too. I have used the 5 inch grinder way too many times and still do onsite.
when you are up to speed then either find someone who will let you weld on thier machines for base rate folding stuff till you know what you like to buy. :lol:

Or,......... I just checked out a couple of online offering over your way and I dont recognise most of those brands. Thats ok though, it would be good to reach out to a fab shop around where you are and see what there using, or not liking etc. when your comfortable with tig you will know what you want to build and then what you need to buy. but a under 200amp Dc inverter( stick welder) with 17torch will definitley get you skilled up, and smiling when you get there ;)

I finally decided on the Ryobi branded TIG200PAD AC/DC welder.
Bought it from the Ryobi agents here.
It comes with a 26 style euro torch and foot control.
The argon gas inlet connection is not the standard 3/8 but that's minor.
Does not come with a stick welding electrode holder. But I got an old one if I need it.
Machine has hot start on the stick option, welds stick much better than my old small pinnacle branded inverter

Used on Steel, stainless and tested on aluminium. All good thus far.

That looks great Vostro. It looks like a tidy unit. I usually dont stick with my acdc unit, thats a personal preference though as I have a seperate inverter for stick. if you do stick with it get a cap for your tig torch gas outlet to keep crap out of it. I usually cap that outlet when its not in use. looking forward to project pics bro :D

Crikey - 200 amps, pulse & 100% duty cycle!

I couldn't find a manual except for the 180 amp unit. Can you supply a link?

It appears that you did well - please post updates as you use it.

Thanks for that. I thought a PDF manual might be supplied - I didn't expect you to photograph it!

It looks impressive. I particularly like the explanation of the duty cycle - 100% duty cycle means that in a 10 minute period you can weld for 10 minutes and rest for 0 minutes. I would have struggled without that!

Please update with your findings as you get the time.

Thanks again Rob.

Regards
Jack

highly unlikely to have 100% duty cycle.

it looks like the typical rebadged unit and the specs are probably highly inflated.
tweak it until it breaks

It seems unlikely but that's what it says in the manual. The proof will be in the trying.
