I've got a mate who is looking at these machines, with an aim to be able to fabricate alloy intercooler pipes for cars. I've advised that it may be a steep learning curve before he can do them. He can MIG weld, but may not have done tig before. he's looking at spending about £800 and the cebora comes with an argon bottle, (although not sure if thats a rent free bottle). so what do you guys reckon, which is the better machine and any other advise you can want to give him.
