Nice steady day today, nobody bothering me and all went well and my lorry phone rang, it was one of our Directors asking if I was on my way back to the works, said leaving in 15 minutes and he asked if I could call round at his brothers as his welder wasn't working correctly. He asked if I had plenty of gas bottles on the truck which I had and said drop the part full one off if his brother needed it. Got to his brothers who explained he wasn't getting gas so a quick look saw a straightforward set up and yes, he had turned his bottle on but wasn't getting gas at the welder. Checked his contents gauge and it said nearly full but we all know contents gauges can lie, so cracked a pipe and no gas, cracked the flowmeter to regulator and hey presto, gas. It turned out he turned the flowmeter right down and forgot to set it when he turned his bottle back on. Got home and began having a nice afternoon and the phone rang, a young lad whose father I know rang and asked if I could shed some light on his welder, he said no power keeps coming, his father is an electrician who replaced the power lead for a longer and larger cable so he could leave it hard wired and move around his garage workshop. Went round and looked at the welder and he hadn't turned the main breaker on.
