Popular Post Raizer Posted January 9 Popular Post Report Share Posted January 9 Mostly posting as it'll likely be the only time it'll be this clean/organized haha Grabbed another trolley from Bunnings as well as a meter of 32mm pvc tube, cut it in half and got carried away cleaning up the ends ha SS filler on the side, alloy at the rear. 11 Quote Link to comment Share on other sites More sharing options...
GARDRB Posted January 9 Report Share Posted January 9 @Raizer why is there a welder on your cat stand? 1 2 Quote Link to comment Share on other sites More sharing options...
Raizer Posted January 11 Report Share Posted January 11 AC seems to work, that's my first attempts at alloy lol so hopefully can only get better from here 7 Quote Link to comment Share on other sites More sharing options...
dmulally Posted January 11 Report Share Posted January 11 I'm about to get 3 phase put into my presently off grid shed. Is it worth making the jump to a three phase welder? I have a 200amp Cebora MIG welder now that I very very rarely run more than half strength via a 10kva generator. But I do have a bulldozer on the to do list which will take some grunt to weld up some decent cracks. Quote Link to comment Share on other sites More sharing options...
tortron Posted January 11 Report Share Posted January 11 You can get them fairly cheap used exworkshop, Quote Link to comment Share on other sites More sharing options...

The worlds ya oyster in terms of cheap (for what it is) used industrial spec gear when you stump up for 3ph in your shed. 3 Quote Link to comment Share on other sites More sharing options...

The 3 phase arc welders are a few hundred bucks if that. Good thinking. Looking forward to getting a big boy compressor too. Quote Link to comment Share on other sites More sharing options...

NickJ Posted January 14 Report Share Posted January 14 Overnight shipping surprised the hell out of me! Total midget compared to the ancient Cebora mig and i'm impressed that the torch and controls don't feel as cheap as I was expecting. Fingers crossed to get chores out of the way and have a play. 4 Quote Link to comment Share on other sites More sharing options...
AE25 Posted January 16 Report Share Posted January 16 Bonus of 3ph is the 415v which means less amps and smaller power cable for same weld output. The two 3ph transformer welders i have actually only use 2 phases and no earth. A similar 300A single phase machine would need something like 80amp power feed. our place has 60a fuses. 1 Quote Link to comment Share on other sites More sharing options...
Raizer Posted January 17 Report Share Posted January 17 Need to figure out the downslope amp settings, seem to be getting half decent results (compared to the mess I was expecting to make at least), but really struggling to finish welds without blowing out at the end edge Also, likely related tbh, but it's a struggle to remember that I just have to let go of the switch to finish, been using lift start for years where you "snap" the arc to finish 1 Quote Link to comment Share on other sites More sharing options...
NickJ Posted January 20 Report Share Posted January 20 I'm pretty noob at tig, my experience extends to telling one of the guys at work what i'm trying to do, they set up the machine for me to then fumble about for an hour learning how to re-sharpen the tungsten... So, hours of youtube later and slightly improved coordination i've started messing around with setting up the machine to fusion weld 0.6mm stainless (for a future project) few holes later and i'm narrowing in on the recipe. The edge came up pretty good while I got way off line on the butt causing a hole which I failed miserably at recovering! My interpretation of the colours is I could do with better Argon coverage? Will have a play with different cups and flows next either way. I had a go at AC aluminium but grabbed the wrong filler rod, maybe next week. Initial impression of the machine feels no different from the one at work, very happy! 2 1 Quote Link to comment Share on other sites More sharing options...
Transom Posted Saturday at 21:56 Report Share Posted Saturday at 21:56 @NickJ did you get the foot pedal included or did you buy the $ 200 foot pedal seperate ? argon reg is included ? Quote Link to comment Share on other sites More sharing options...

So my problem appears to be talent. I'm definitely guilty of too much heat, it happens quite fast and I'm still arranging the coordination to keep up. I'm actually finding it quite exhausting, so far i've made every rookie mistake including removing the tungsten only to sharpen up the filler rod, needless to say the brain had a wtf moment when that hit the wheel! I've watched a few of that fellas videos in passing, so much to learn and then translate to muscle memory. On the progress side, laid my first ali beads, have to say i'm not sure what I was so nervous about! Started at the top, the bottom was me playing around with 4t and using the torch mounted current dial. Not going to win any art awards just yet, but enough to be encouraging to continue learning. Hoping to find some more scrap this afternoon to stick together. 2 Quote Link to comment Share on other sites More sharing options...
mjrstar Posted Sunday at 00:06 Report Share Posted Sunday at 00:06 If you are struggling with too much heat on thin aluminum and your machine has a pulse function it's worth having a tinker with. The other thing is when playing with small bits of scrap they heat soak very fast and behave differently to a larger part. (far more likely to sag out) Once the work piece is too hot its time to do something else for a bit. Quote Link to comment Share on other sites More sharing options...

I plan on getting a pedal in a few months, until then its fumbling the dexterity to operate the dial and keep the electrode steady..... the Heatsoak is impressive, started out at 120A (10mm Al) after a few of the above beads I looked over and noticed I had turned it all the way down to 20A I have played with the pulse on steel, really cool, but the number of settings gets carried away, any rough starting points for Al?
