I have recently bought a Lincoln, I think its a 135 or something like that. It has the gas attachment. Can tell you this, the body shop guys will not even touch one if it does not have the gas. Mine costs abuot 550, but am very glad I stepped up to the gas. I can tell in one second when the gas is not there. Smooths out the weld, more forgiving, can weld thinner sheet metal.
My 2 cents worth

From what I can tell by researching the 135 Lincoln is basically the same as the Weld Pak 100 but it comes with the gas attachments. When you read the specs on the two they are the same unit as far as Amps and thickness they can weld so it may be worth the extra to get the gas right off the bat. How much does a gas cylinder run and how long do they last?
Thanks for all the info everyone, I'm learning a lot fast. Hopefully I'll be welding soon.
