Must say what a good site you have, been looking around for a couple of weeks now for advise and couldn't find anything. I've done a bit of arc welding a long time ago, so i didn't have a clue where to start, only been at it for about an hour or so and picking it up very quick thanks to all the advise of your site. Got my first project on the go (an old trailer that needs to be bigger). A guy at work had a clarke 100e laying around in his garage which he had never even used, so the nice man gave it to me, thank you very much (o dear he has opened a can of worms for me now). The only problem i have is do i get disposable gas or go to boc !
