    Default air comp. with bobcat 250

    Got a brand new bobcat 250 that I'm picking up tomorrow and putting it on a new rig. I'm wondering if I should go with a electric air compressor over gas, so I guess the question is how will this bobcat weld/gouge while running an air comp? I haven't bought and electric comp yet but it will probably be an emglo

    Pretty limited gouging on a bobcat, actually I've never heard of anyone doing it on such a little machine...As for the air compresser, nope, you'll need a gas driven unit.

    Well the 250 is rated for 3/16 carbons. I do it everyday with my 200 amp aead. As long as you have a 100% duty cycle machine you can do it. You can gouge with 100 amps if you get the right size rod. I'm not cutting through 2" plate with a gouger... I'm just taking out broken welds and old dump truck floors etc...

    Standard size carbons are usually 3/16 or 1/4". this is right from arc air guide. 1/8" minimum amps 60 maximum 90, 5/32" min 90 max 150, 3/16" min 200 max 250, 1/4" min 300 max 400, you can burn 3/16 carbons all day long with a 225. I have never came across a job that I needed a gouging rod bigger than 1/4"... if so I will just burn it with a torch.

    Default air comp. with bobcat 250

    I can't gauge with bobcat 225 & 3/16 rods just note enough amps. I run pretty close 300 amps on my in shop welder.
    I can't comment on the 250 but there is not a lot of difference in the 225 & 250 and I know how many amps it takes to run them on my old 500 amp welder. I tend to agree with cruizer or as weldonwelding pointed out drop rod size. All though I don't really care for the smaller rods.

    I burn 3/16 carbons all the time with my aead 200le. It burns em pretty nice... although if I don't have over 80 or 90psi out of air comp it doesn't burn that well. The miller book says the 250 is rated for 3/16 carbons but doesn't say anything about the 225, I would think it would do it though with 200amps 100% duty cycle. I was in a jam one time and burned a few 5/32 carbons with my Max star 150... it worked but didn't burn very fast

    Like cruiser said, if your going to use it for this, get a gas powered compressor. That way your not reducing your available power output from the Bobcat. Otherwise the compressor is using some of your electrical power that you will be needing for the rods you are using.

    Everyone of those little machines I have seen that was used to do a lot of gouging has blown up. They do not do a good job of removing material and always seem to leave a carbon deposit in the kerf and they don't have the balls to get under the deposit and remove it. Just my opinion.

    If it was me I would get the gas compressor. That way they are independent of each other. If for some reason your welder quits & you need to borrow/rent one it may not run your compressor.

    Does the Bobcat have seperate aux. power like the Trailblazers do? If not another reason to go gas comp.

    This will be just another addition to the other 2 rigs already set up with a gas compressor. Only reason I asked about this is because it just seems like a lot of generator power compared to my other welders
