Due to problems with email and admin is no doubt busy with fabtech, i will try to manual activate accounts, which may take a few days.
So please try your account in a few days.

By the way, wanted to let others know here that emails from this forum are being Junked as unverified sender by Outlook. And when I tried registering with a Gmail account (MosinVirus) no emails were being received at all. I am guessing Gmail just rejects them. Just FYI thank you for that. that expl...

good move jumping on the training.
looking like a good start there.

hi,
just a reminder to clink the link in the email you get sent when you register, to activate your account.

i just got some carbon brushes that thread into a 17 tig torch. just trying out some electro polishing on some stainless tubes i'm welding up. just using some left over phosphoric acid at the mo. whats best dc current or ac ? trialing it on my old ac/dc tig, so i can do both. - or + ? ac balance ? t...

I don’t know “green machines” but I do know polarity. Yes, for steel, torch needs to be in a “NEG” plug so that you run DCEN. But he’s welding ally, so that’s AC, switching between polarities. On my Miller Dynasty, it’s one plug, a button to swap polarity. even on AC its needs to be correctly conne...

is it setup correctly? usually sensitivity setting and delay. sometimes people set them less sensitive to avoid sun light or shop lights triggering it, but then have issues with arc triggering it. usually have the delay long enough to be annoying. no dirt blocking the sensors? film on the front? new...

welcome

quick question, did you have any issues signing up to the forum?

i think hes making manifolds. thats a pretty common method here for turbo manifolds.

i don't normally do much that thick so i'm sure others will have a better idea than me. however it looks cooked, typically that means travel speed to slow. going fast enough on small diameter tube/pipe is a challenge. that looks like a single pass to me, i would try doing 2 passes instead. also use ...

hi can you post some pics of it? what amps are you using? cup size? as many details as possible please. from what i can see is your welding a thicker bit and its really really cold. that could be from poor earthing. always best to earth directly to the work. tho i often use a third hand to bridge f...

sounds like you need to practice thinner material. you can still use the big machines, as long as they are not running really big wire.

afaik you can use c10 on short circuit mig. i havn't done it myself as our normal mig gas is tri mix which you can run in spray mode.

i use a floor standing lamp like builders etc use. that way you can put it back enough so you don't cover it in splatter.
also if you can use multiple lights. you want to avoid creating shadows.

was the forum registration signup ok?
any issues at all?

the scary answer is people have died from welding in enclosed spaces. welding fumes are bad. not only from argon replacing the air you breathe, but also all the fumes. my previous work the main welding station the guys had a fume hood and ventilated helmets. meanwhile my station just had standard he...

Had 40 EP machine only goes down to 20 I think it might help if I had more amps but don't have 220V had hard time getting filler to melts that's why I hit tungsten and took forever to create puddle. It was thicker aluminum was just practicing but think I need some thinner stuff since I can't get la...

with such low amps i would try some aluminium sheet eg 1/16". the most common beginner mistake is not enough amps for the thickness. aluminium needs truckloads.
also use a small cup, say a 4 or 5. balance start with 30.
try not putting so much filler in as it cools the puddle.

if your going to practise tube, then back purge. you need to know if your penetrating etc so you need a clean inside bead.
plus you need to practise purge setups.

to practise without purge, just pad beads on a thick plate.

why is it yellow?

maybe do a bit of part time teaching, get those young ones into shape.

keep at it. teachers can be crap, they are human.
i suggest to do practice outside of class so you can work at your own pace. it can take a bit to get comfortable, get that confidence up.
