Hi, I'm looking to buy a welder for at home it would be mostly for bike/trike related work, I've been using an old arc welder of my dad's and have used mig for bits and pieces at work. Mostly it will be used to add on to an existing frame but eventually I'd like to progress onto making frames and tanks etc so I'd like recommendations as to manufacturer and type? I know you can mig a frame but can you use it for tanks? I'm hoping to spend approx 300 for the machine I know I will need extra items
