If I'm not mistaken, the compressor will kick in when the tank pressure is getting too low.

 

is that on most models? (sorry for the newbness)

 

Yeah, occasionally, ours will kick on for a minute or two.

 

Woo hoo!! Here's another vote for Harbor Freight. I do a LOT of tool shopping, and so do my blacksmith/bladesmith compadres. Most of their stuff, if you put it next to the name brand, feels and looks exactly the same (except the house color is orange). I've had occasion to find a tool that had DeWalt parts on it that was being sold as "Central Machinery" and cost about 40% of the name brand tool.
There are a few things that I won't buy from them (like bandsaw blades) but the list is VERY small.
There is NO excuse for anyone who can afford to tune and mod their car to not own at least an inexpensive impact wrench.

</soapbox>

 

I like that way of thinking

 

No matter how good the price was It's a piece of crap. I took it back yesterday. I was about to install my springs, so obviously first step is to take off the wheels. The thing could not even lossen up the wheel lugs.

So the Impact wrench had to go back to where it came from. As said by someone else, I'll just save up and get some air tools instead
