I have been self teaching myself welding for a year or so. I picked up the cheapest entry level MIG (Clarke Pro 90 MIG Welder) off ebay and just went at it. Some other kind folks at Hackspace (Steve and Neil) showed me some arc (MMA = manual metal arc) and gave me some time on a proper MIG setup which made be realise how "Pro" has no place in the name of my Clarke Pro 90. So when another member (Barny) posted a Beginners and Improvers Welding course at Easton college I thought it would be a good idea to get some proper training and fun too. So this is what we learnt.

TextStar is a small LCD (liquid crystal display) that is easily controlled using basic serial command from and Arduino or similar. Great for debugging and has a some nice bar graph features built in. Not very cheap tho.
