There are two electric welding sets in the space. There is a basic red arc welder (on loan from spooq) and a larger blue MIG (I think) welder. | |||
There is enough PPE for one person. | There is enough PPE for one person, two if you can find another pair of overalls. Steel toecapped boots are highly recommended. | ||
The small red welder is usable. There are some 1.6mm welding rods for mild steel in a plastic tube. Please close the tube, welding rods absorb moisture. | Individuals could practice arc welding with the stuff we have at the moment. One on one teaching could be done with the stuff we have at the moment if you are careful. | ||
The important part is safety, someone who can operate the equipment safely can teach themselves basic welding by practising. | |||
The small red welder is usable. There are some 1.6mm and 2.5mm welding rods for mild steel in a plastic tube. Please close the tube, welding rods absorb moisture. | |||

A freestanding folding welding screen has been constructed from fire doors. It can stand by the wood store without taking up a lot of space. It could fall over in some configurations and is very heavy. Please have at least two strong people move it. It needs a bit more work on the feet. | A freestanding folding welding screen has been constructed from fire doors. It can stand by the wood store without taking up a lot of space.

It can be used for practice, the first attempt to weld a bar to a plate resulted in a very poor weld due to inexperience and because the plate melts before the bar gets hot enough. Note : practice on thick stuff. Practice even just running a bead along a surface without attempting to make a join. Thin stuff is hardest. | It can be used for practice, the first attempt to weld a bar to a plate resulted in a very poor weld due to inexperience and because the plate melts before the bar gets hot enough. | ||
Some acceptable welds have been made joining some thick chain to the end of a steel scaffolding pole. | |||

The welding equipment pledge hit it's target a few weeks ago but nobody has got around to collecting money. Mailing list discussion last stopped at a suggestion to talk to [[User:t0m|t0m]]. | The welding equipment pledge hit it's target a few weeks ago but nobody has got around to collecting money.

More scrap steel to weld would help. It would be handy to have enough PPE for a second person; mask, overalls, apron, and a second set of ear defenders to wear while using the angle grinder. | |||
We have one automatic welding mask and one welding mask that is always dark. The automatic mask is a lot nicer to use. | |||

Could we find some fire resistant fabric material that could be hung from hooks on the ceiling/some sort of ceiling curtain rail to use as a welding screen? | Could we find some fire resistant fabric material that could be hung from hooks on the ceiling/some sort of ceiling curtain rail to use as a welding screen? | ||
