Negotiations with the kat have continued and a deal brokered. In return for resuming the provision of food to the kat she agreed to buy me a brand new Lincoln Powermig 180C for my birthday
. I have just picked it up and, as agreed, have given the kat a teaspoon of kittykat (well the agreement made no mention of quantities!!!!! 
)I am in love with the new welder......runs like a Rolls Royce....wow
I have also changed the BOC gas cylinder (after 20 minutes of paperwork
) and the old welder performs lovely again (ready to give it back to its owner). Guess oils aint oils and gas aint gas!!
