Hi again not got anything really done over the last few weeks am busy with university exams... my finals but am just having a bit of a break.

Ive come to a bit of a dilema with my robot as in I want to start making it out of metal but have a few dilemas. Main dilema is that I need a welder and dont know wether to go for something like a cheap and chearful arc welder that will probably set me back £80ish pound after all gear is brought or wether to go for a DIY mig something like the clarke 90 with gear and gas would probably be around £300.

Also is a box frame the way to go or is there a better way to do it?
