Welder repair

An ancient proverb says that power tool failures occur in threes. During the same week that the lathe motor burned out and the compressor wire meltdown has turned it into a scary noise machine, we also had a mysterious malfunction in one of our welders. It didn’t release any smoke, didn’t make weird noises. It just didn’t weld. 0 volts across the output.

This machine, a small 180A TIG/MMA inverter welder, has recently been repaired. It was not used heavily, as TOG has only so much use for welding. In fact, it was only used by a couple members to practise their welding skills.

On one hand, this machine was 5 year old, has been used extensively in the past and could have been written off as death of old age. The cost of a commercial repair would probably exceed the value of the welder. On the other hand – why not try to repair it ourselves before scrapping it?

After several weeks of prototyping and experimentation, and only one week left before the Faire, we got started in earnest.

TOG’s MakerBot

TOG now are a proud owner of a 3d Printer. Lets start to make some nice projects.

Spent almost 2 days building it and getting it to work with a few small changes made with extra washers. Also added in extra screw behind main Rep Rap board to hold board, had to put away from plastic from power connector to get in nut.
