If this is a straight generator machine ,I would say 'go for it'. If this particular welder is of the variety which uses rectifiers to obtain the DC , ( the welder would also have an AC welding output) Then I would want an extended trial usage before commiting to purchase.
This is my personal preference, as I find rectified current somewhat lacking when it comes to making code spec pipe joints.
I find the 'Dual Power' option very interesting, what can you tell me about it?
I hope you find this helpful, Ed.

The Pipe Pro is an inverter based machine that will be at worst as good as a generator type machine. Just because a machine is a rectifier style machine does not mean that it has AC weld output. There are many in use on pipelines in North America at this time with very few problems or complaints. The ease at which the arc can be fine tuned to the preferance of the welder is one of the biggest advantages. The light weight 1,010 lbs full of fuel and it allows you to see out the back window of your rig. The weld at low speed with out sacrificing any weld performance saves on fuel. Hope this helps.
