Not sure on the "wildcat" but i have a "bobcat 200" had it for 20 or so years i guess and i love it. Got a Onan for power, its real smooth when stricking an arc and steady governor and power once the arc is established. Only problem is its a bit hard starting, guess its kinda cold blooded and it needs to run a few minutes to warm up before welding and its LOUD! Did I mention its LOUD? other than that Great machine!
