After a few attempts welding scraps together my disposable gas ran out very quickly. I found some replacements in Halfords but the first one of those also ran out very quickly. The lads on the MIG Welding forum put me in contact with Weld-Air Supplies Ltd in Dunstable and I took a trip up there to collect a nice big bottle of argon. That needed me to get a new regulator and there is a deposit and a hiring cost but that is a small payment for 3 years rent. The initial bottle works out about 1/2 the price of the equivalent in disposables and if I get it refilled in 3 years then the price will be significantly less (and I won’t be left with lots of empty canisters).
Once I’d strapped the bottle to some shelving, I needed something to test it out on. I decided that my TIG welding was getting good enough to try a little project. So I decided to make a little battery box for my solar powered light project, it is a little overengineered just incase. I cut up some 6mm mild steel bar, filed off the millscale. I filed angles on the end to make it easier to weld.
Clamping up the frames square was quite difficult and I managed to weld one of the bars in the wrong place so this resulted in the frame being skew in one direction. The resulting frame is solid and I should be able to use it as it is. I have some thin metal strips that I plan to weld across the bottom to form a shelf.
