Yes you did.
I gave advice in good faith which incidently would serve the OP well whatever material thickness he was presented with for his test. Granted if he was given a hefty piece of plate it would take a while to prep and weld.
You on the other hand have offered him no advice and...
I'm not saying either. It's horses for courses, dip and spray have their place but to say you always need to be in spray transfer and that dip transfer doesn't penetrate enough are very broad sweeping statements that are incorrect and may confuse people.
I imagine you will use spray...
Mad Mick gives good advice. Positional mig is a ****** if it's going to be tested- it's the easiest process to look good but fail a bend test.
Overhead butt you want to be going for lower range dip transfer (19 ish volts and wire feed to suit). 2mm root face and gap but slope and tilt angles...
How are you coating it? If it's going to rust how about making the top keys out of something non ferrous to contrast with age- copper/brass maybe?
Just my art ignorant 2p

This is the guy that Al was on about in post #8 (I think) he's got some good feedback

Magnesium based wire will feed with less hassle, can you hire a MIG set for the job?
Shame you're not closer I've got just the machine for the job and no work for it :(
All the best, Jim
Hello Richard,
It'll be fine and you'll run 3.2's all day (or for as long as your duty cycle allows). I did the same with mine, I got a good length of the thickest rubber cable that would fit into a decent rubber 3 pin plug and put a 16A socket on the other end.
Enjoy your new stick...
No it won't, that rivet cutter was the ideal tool for what you did. A gouging nozzle forms a U shaped groove to remove a weld defect or put a prep on a butt joint in thicker plate- it's not designed for cutting all the way through. If you have a look on Sub-arc's link they tell you how wide the...
Gouging nozzles have a similar hole pattern to normal cutting nozzles but the centre hole's much bigger and set back, they have a skid on the bottom to scrape along the plate.
All the best, Jim
