Thread: Pontoon Dingy build.

You still using the BOC ac/dc? Rate it?

The single phase caddy? yep welded all the pontoons with it.....110-115a AC 5% positive, that is realistic maximum for continuous welding with it with a 2.4 tungsten and a no cooled torch. I rate it for purge welded ss DC on lighter stuff. ally 3-4mm is really max for a little job 2-3mm max bigger job.
Generally use a 300amp ac/dc 3phase tig with water cooled torch for most work as it is more adjustable/powerful but I didn't want to tie up that machine while I was perking, but for the money they charge the little single phase is a nice welder for sure.

Yeah its so fricken cheap, although they did just put the price up.

The next cheapest 'name brand' seems to be the Cigweld (esab) @ $2100ish.

4mm is probably on the light side for what I'd use the Boc for tho.

Hmmmm i say. Hmmmmm.

All depends what you are doing with it?
Small jobs you will do 6mm easy but the handpeice wont handle 180amp constant and neither will the powersource.
If 4mm is about as thin as you would use I would be looking more in the direction of a mig than a tig unless as I said very small jobs that have to look nice.

What model welder are you using there cam? Is it any good for steel?

The Tig or the Mig? the tig is a boc branded ac/dc.

https://www.boc.co.nz/shop/en/nz/boc...oc185acdc-fc-p

Its a nice little single phase unit for the money but be aware it wont run 185 amps on stick,it must run more volts and less amps for stick(stick requires more volts for stable arc esp with low hydrogen)

The Mig is a Ewim? it is a pretty flash programmable pulse mig but with the push me pull you handpeice some parameters are not user adjustable and it has a habit of loosing its shit and you have to get the rep in with the laptop to reset parameters which is as gay as a handbag full of rainbows.

The other two we run on steel with no pull handpeice are great.....force arc is incredible.

Bungs in,transom wood in,seats in.

Maiden voyage a success, I am very happy at this point.
Stable ! shit yes!.....lower minimum planing speed than the 10f Parkercraft by quite a bit and only dropped around 1-2 kph top speed with the 8hp yam.
Also even with the low transom and allsorts of being a dick/worst boat handling practices I could not get green water over the back into the boatGranted it was flat calm but doing the same in the Parker would sink it.



Being so flat it barely makes any wake at all so despite my best efforts to stir up some chop to test it in that will have to wait for some real chop.
My full 100kilos sitting on the aftmost corners with nobody else onboard it wont dip a corner under,certain swamping in the old girl.

Looks like it draws like 3" haha that is awesome!

Really good shit VC. Hats off to you on the whole project.

BOC had a special on their little red caddie stick and Tig, I believe $350 plus. Had a guy bring two into work for T&T. They have a 15 amp plug,

$350 for a TIG? Did it accomodate gas or is that run seperate? Sorry I've never had anything to do with TIG.

That looks epic Cam, looks like you could just lift it onto the back of a ute. You'll start receiving orders soon.

Maybe a singlecab flat deck.

When's part 2 VC? The trailer build story

Time for the 4.5m big brother
