Hi just starting out. Want to buy a mig welder, mate can supply a large bottle. Want something decent that would allow me to do most things & 'grow into it'. Want to make railings & generally fab stuff. Also what about a metal cutter wot would you suggest. want things that are more than capable rather than should do. But also don't want to waste my money. Likewise a mask wot good one would you buy. Thanks alot
