Me again...
Switched to a water cooled torch as the original ones were overheating a lot. With a water cooled torch do you still use the oversized tips for alu wire? Or go back down to same size? As keep getting some odd things with the wire hitting the job and just burning little messy bits of...
Had good luck with this last few tries, seemed to be a case of getting the machine settings bang on rather than anything else for sussing the vertical up bit with the E's technique
Thanks for all the help guys
Yes when I build the deckhouse I am seriously thinking of hiring a better machine but need to find a hire shop that will help with settings etc or I may as well use my own machine that I know
Cheers guys will bear those bits in mind for next session.
The stickout is not helped by the fact i keep struggling with the blob melting on to the tip when finishing a weld, I think I'm holding too far off because of that. I end up pushing an extra bit of wire out with a trigger pull after...
Pushing as in the torch facing uphill, going upwards.
I was going opposite way before, going upwards but torch facing downhill as I thought the weld had to sit on top of the previous bit of weld.
Did a bit more this weekend.
Actually managed a bit of vertical up which looked reasonable... pushing... thinking **** have I just been going the wrong way.
These pics are all from welds done flat, any advice from what you can see in the pics?
Ok thanks for the answer, I've asked some crane companys how much to shift a 63 foot trawler to the local duck pond. Do you think it will be calm enough in there?
I'm finding it gobbing up and dripping down the joint rather than leaving a bead. Have I just got too much wire?
(using the same settings as seem to work ok on flat welds, about 70% on both voltage and wire on the rtech 250)
Having fun fabricating some bits of boat. Some of the welds even look alright.

When doing vertical do you have any advice? Up/down? Angle?
Still having some trouble with burn backs sticking to the tip (welder has no burnback adjustment)...
What's your pulse machine? How much would we be looking at for one that will do 6 and 8mm material.
I want to build an aluminium tender at some point so might be worth investigating.
Welding question again....
Doing a fillet weld which is overhead... I'm having a nightmare. Managed to keep the wind off so it hasn't gone porous but I can't get a bead. It seems to penetrate but just dribbles loads of metal all over. Too much wire?
Yes I have seen this problem, I was just going to bed it down on a load of sikaflex type snot. I've got some epoxy paint spare but I'm not sure if it sticks to ally.
Yes bit of a vocation!
For some divers, 8-12 depending if they are technically inclined or not.
She's in Lancaster at the moment. Probably staying there but venturing out to the irish sea, isle of man, northwest approaches, hebs etc.
Yes marine grade, 5083. Although I did make a load of bits...
Hey up
It's a Danish ex-seine netter, 19m, 1966. I'm rebuilding her into a live aboard dive boat.
This first job I am doing is new stanchions, the old timber ones are leaking around and a little squishy, so cutting them all off, fitting a new covering board around the deck. And making new...
Should be clean, it's new material.
Some of the other bits that I need to attach to are outside though and have been there 20 year.
p.s speaking of material would you recommend any suppliers of 5083? This lot came from aalco, some others didn't seem keen delivering to lancaster
Will take a close look when I'm there, but I think they were just flecks of contamination not bubbles.
The bits were cleaned with a zip wheel on the grinder. Is that enough? Or should I be wiping them with thinners or something?
