Hi i have a Clarke 151EN that i carry out car body repairs with. i am using 0.8 gassless wire at the moment but would like to try 0.6 wire. i have tried today to buy some but have been unable to find any. Does this stuff exist as gassless mig wire or is it only available for using with a shielding gas?. also if it does exist where can i buy it. regards Jeremy.
