15% mix of what ? You just want pure argon not any sort of mixed gas, unless your using Helium for some strange reason.

I'd be tempted to cut the channel as accurately as you can, place on gunwale, small minimal holding tacks with arc, remove, place on quay/or boat with big bit of something i.e. Ply to protect fiberglass from spatter. Tack it to hold it properly, then arc or take home and tig.

What are the chains made of? Mild steel will infect stainless, and it will start to rust. Infect is not the right word obviously.

yeah, mild steel, but that's just the nature of it, they are work boats hauling crab pots, servicing mooring chain, pulling all sorts of crap.

When I say channel it's kinda custom channel, not cut from a length. Imagine cutting 2 side plates that get bolted through the gunwale and then place a piece on top to cap it. It's kinda hard to explain in text. I might take some pictures

Pictures tell a thousand words.

If it's going to be abused with steel chain, for economy, v the joints, arc it, sand it flat with a flap disk.

No ones going to appreciate pretty tig welds, covered in rust from chains.

What thickness channel will this be ?

Once again, tigging is a more expensive process due to the gas factor.

If it's purely functional, arc it, sand it flat, job done.

probably something like 4mm

I was just thinking that any chance to practice would be worthwhile with the tig.

Is there any strength difference between them?

No, I don't think so, just a question of amps and penetration.

as you said, any tig practice is worthwhile.

Sorry, went off topic I’ve been looking at the 15% Argon/CO2 for MIG just surprised by the price

Sgs gases.

I used to get mine through the motorfactors,
Partservice and mpd. (For 10-20l)
But now use denleys in honiton as they stock the 30+50l rent free sgs bottles.

is there any difference in price between SGS agents?

I paid the same for a 30l 15% mix for MIG (SGS) as @Ruffian showed on his SGS price list. Mine was from Leamco autofactors...

Apparently they can charge what they want.

Yes but that is a price from the distributor I use in honiton (circa 15miles from where the OP is)

Is Honiton the cheapest for deposit? Or are you only going there for the larger bottles?

Unit arrives Monday, still not sure if its overkill for my needs. Got the weekend to try and keep justifying it to myself.

Was that eBay helmet I linked to earlier the right one? Don't wanna end up with a cheap duff one.

Honiton denleys is one of the few places round here that keep 30-50l bottles.

Can get 10 or 20 fairly easily from most motorfactors and other places.

As with machine, I wish I bought a ac/dc machine straight off. As had 2 dc only machines before and should learnt my lesson.

The parweld lid you showed in the Ebay link does look like the true colour one.
Check with some welding supply companies also directly as sometimes get a better deal rather than through Ebay as they dont have to cover fees.

Ahh, Honiton, I know it well, good friends there.

Exactly, seems there must be some standardisation if we have the same prices many miles apart...

AnthonyExmouth · Mar 19, 2021

Can anyone recommend a starter list for the consumables I should be looking at getting. Just a kinda starter kit that'll get me going.

Barking Mat · Mar 19, 2021

Tungstens come in different flavours and sizes, you'll need matching collets for the tungstens , and then ceramic cups. That's about it apart from filler rods. I think.

Stainless tungsten and alu tungsten are different, but you can buy tungsten with cover anything, I believe, but I can't remember the name, people have raved about them, Huntingdon multi strike?

My memory is a bit crap at the moment.

I am using 2.4mm pink multimix on everything now.

Are the kits i see being sold worthwhile or am I better buying separately? Is it worth shelling out on gas lenses for learning? Is there an ideal setup for practise?

AnthonyExmouth · Mar 20, 2021

Well, I've taken it out of the box now,
