Looking for a good welder to do some misc fabbing on my car. Will not exceed 1/4" MAX thick metal. A former co-worker has offered up his Lincoln Elec 5000 hd, auto tinting mask, tank/reg & gloves for $600. Is this a good deal? Also this is the same exact welder I used to use at work and learned on this system and can say I LOVE it, just trying to see if the price is reasonable??? Thanks!
