From what I understand the Vantage cannot do scratch start TIG, although the PipePro 350 is able to.
In terms of welding capabilities I find they are pretty much exact. I have scene the proven reliability of the Perkins engine on the Vantage, but the Mitsubishi engine on the Pro 350 I have no idea about.
Is the purchase of either just based on preference, because both are excellent in all welding processes?
Thanks very much!
