Hobart195157R Replacement Gun for Handler 125EZ and Handler 125 Wire Welders

I have the 125ez and want to add gas to get cleaner welds, looks like this replacement has a feed for gas? the tube curled on the right? thoughts?

I just need 1 cable

Can u get a longer gun cable for this welder?

will this take a nozzle for the gas. I see that this is adaptable to the gas conversion, but the nozzle that it comes with is for flux core. Thanks
