    Default air carbon arc gouging?

    Hello everyone I have been thinking about buying a air carbon arc gouging torch to add to my collection of toys, I would be running it on my TB302 was curious if they are worth while having I seem to get a nice but of heavy repairs on construction equipment between buckets, stick work and sometime work on the undercarriage I figured it would save me a lot of time with a grinder?? Hope someone has a better clue thane I have never used one

    they work fine on the heavy stuff, we used them all the time in the ship yard, a good tool to have if your shop can handle the sparks, they can shoot over 50 feet, so one must be aware of that, noisy too

    Do you have a good air supply? They tend to need a lot of air. I run an Arcair K2000 which is considered light duty. (see link below) It uses the least amount of air. I run it with an IR wheelbarrow type compressor that just barely keeps up. I also have a K4000 which uses a lot of air. I can only use this when I am at a customers shop that has a big compressor. When needed they are priceless IMO.

    PS - use ear plugs with them & watch where the sparks are shooting.

    Default air carbon arc gouging?

    Mostly use my Hypertherm 85 with gouge tip, you turn it up or down as needed. I bought another hose so i can just plug & go when need.
    Still keep carbon arc for hard to get into areas but hardly ever use it anymore

    Ok thanks everyone for the info I am looking at the 4000 I believe it's called so by the sounds of it, it requires too much air and my air compressor won't keep up

    Reduce the size of the holes in the K-4000 down to the size of a K-2000. It will lower your air use to make it work just like a K-2000.

    If you weld on heavy equipment a air arc is a must, you dont need a big one because you should only use 3/16" carbons of the Trail Blazer, You can run 1/4" rod but its not recommended.

    A compressor with a 30 gallon tank Two stage with 13 HP honda will run it just fine.

    The air compressor I have it a 5.5 horse Honda wheel barrel style and I have a volume tank I take also with it as well, what do you mean by reduce the hole side in the K-4000? I haven't really looked at one too close to know exactly how they work my one supplier has one on special right now and interested me

    Look at a K-2000 (aluminum Jaws), and a K-4000, and you will see the different size air holes in the jaw tip.. It's copper, or some alloy of it, and you could tig weld/braze it up. I could give you the diameter of the K-2000 air holes if you like?
