It is not positive nor negative thinking it is 30 years experience welding. I am not knocking the welder I am just stating that it is not the machine you would want to be using welding up such a large project.
A flat plate, contoured bumper will require many feet of weld and a little hobby fluxcore welder is not what I would want to use.
A 20% duty cycle at its limit is going to cause you all kinds of frustrating delays. Every time you overheat it and it shuts down you will have to wait for it to cool off before you can weld again.
Like I said it is ok for sheet metal or welding up mufflers but for such a large project to me it will be time consuming and not worth the trouble. Sure it can do it but why, It would be like eating rice with chop sticks one kernel at a time, by the time your done you used more energy then nourishment received, and your still hungry.
Take your time tack it together with the 110v welder then when your ready to finish it go rent a decent 220v one for the day and finish it. Your welds will look better, better penetration less grinding and you will be done in a day instead of a week.
