I have learnt so much with these posts and it has stopped me buying a cheap tig welder as I now know that I wouldn't be happy with it. I remember the industrial Tig welders when I was working I never used them but I understood there capabilities and would have found the faults with a cheap one. Another thing a broken band saw blade its been mentioned here that silver soldering could be used, mine has broken on the weld, if it lasts for a few cuts I would be happy with this as it will only be chucked.
I remember when I was about eighteen I mentioned to the foreman that I had done apprentice stick welding which was a basic, I was no welder. They sent me to All Can which made aluminium cans and lead type tubes, when I got there they wanted me to weld these six inch by approximately thirty foot steel bands cut at a angle then arc welding them and fit the band on the rollers ,this was dipped into molten lead or whatever and then cooled in water and a strip of lead came off the belt. This strip was then punched into discs. If the weld lasted an hour before they broke that was accepted, mine at first about 10 mins but I improved and become quite good at it. That has been my only experience of welding to date so I'm looking forward to getting this welder in the near future.
