Dissolved Acetylene Suppliers - Rent Free?

Having read the posts in this thread, would anyone have an idea of a gas that could be used for lead welding? (Apart from Oxy/acetylene of course).

TIA

For Lead, pretty much anything. Propane would be ideal. The melting temp of Lead is so low. I have even soldered with a Weller gun iron successfully.

Thanks for the info Steve. I was hoping to be able to achieve something like this. Lead welding.

I used to rent the cylinders from BOC but had to cease when the prices soared to silly levels, (for my amount of use)

I have a roofer friend who does some very nice lead welding for his customers.
He uses Oxy-Propane for all his lead work.

If you're only interested in small torches, consider using a medical oxygen concentrator, rather than renting or buying bottles.
I've not really tried lead welding, but use Oxy-Propane for general heating, silver soldering etc, and the concentrator works fine for me, up to about 85% O2 @5l/m
Mine came off Gumtree from a glass bead maker, for les than £100, who was moving onto a larger system commercially.
Tuffnell Glass have some useful info.

I'm slowly working through my C&G Level 3 in Fabrication and Welding part time via Leeds College of Building at the moment...

It's not "Cheap" per-se at about £250/module, but that price is very inexpensive for 48 hours of contact time per term, all materials and 6 assessments per module.

I didn't intend to do the TIG modules as it's not really relevant to why I want the qualification, but it's do-able whilst I'm at it if I feel it's going to be worthwhile.
