I put in a 3.2 when I had the machine at 200amp for some solid alu round bar...never changed back to the usual 2.4. Seems to weld at 140amp as well as it did with the 2.4 tungsten I was using previously. I think its the new gas lens for the 3.2 helps but wondering what peoples thoughts are.
Quick google suggests if you sharpen it properly then it doesn't make much difference.
