high duty cycle 120 volt MIG?

[welderdude]

Anyone here ever come across a 120 volt MIG welder that has a high duty cycle? I have been wanting a 120 volt portable mig welder that can run at full power for more than a couple minutes.
I have entertained the idea of buying a Hobart or Lincoln 140 amp mig and building a tank to hold the transformer in mineral oil so I can use the hell out of it with out it overheating.

We have one coming out. It will be 35% duty cycle (or thereabouts) at 140 amps.

That would be nice!!!! I have tested many red and blue machines of the 115v persuasion for a service machine on some thin parts I make. But I have not bought one the duty cycle on them is not near what they claim.

Our 110v 140 Mig is a very efficient unit i can run our model where with a lincoln migpack will throw the breaker . I know this because i have done it. And the migpack is lower top end and less duty cycle. The I-Mig 140 is 35% duty cycle .
There are a few Body Shops in the GTA area that are purchasing this unit and the Rep selling them is demoing using Aluminum through the Mig Gun to show how effective it is.

We have had this model in Stock here in Canada for the last couple of months.
