Power inverter/110 welder

[HawgEnvy]

Well, I've been wanting to add an onboard welder to my truck for quite awhile. But I got to thinking. Why couldn't I use an inverter with a small 110 welder?i found an 800w inverter on Craigslist for $50. I was thinking I could hard wire the inverter direct to the electrical system using (?)size wire and a (?)amp inline fuse and mount the inverter under the drivers seat(or wherever) to plug the welder in. It doesn't have the "cool factor" of a weldernator but would be more practical for me.

Does anyone see any problems with this setup?

What is the draw of the welder. I doubt the inverter would handle the welder. A quick look found a 110v welder from Harbor Freight pulls 20 amps at full load. That is 2200 watts.

Yeah I've been doin some homework. It's going to be cheaper and more effective to to build a weldernator. But to answer your question(kinda), its just a Harbor Freight 110v wire welder that a friend has. I'd rather arc weld anyway,lol.
