I'm not sure but I guess the actual weld would burn it off whereas casual spatter near the weld may not do so so easily? I'm sure someone will be along to tell us. ;-) Cheers, T i m

I would be using a stick welder on that. I only use MIG, where the stick would be just too aggressive and burn through the steel. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk

The half tonne braked trailer I built with the same stick welder over 30 years ago and has evolved a couple of times along the way is still going strong. ;-)

Continuous wire feed, no stopping (provided you have a good duty cycle) no chipping slag, no more inclusions in the welds, less heat-less distortion, the flash is more shielded better on the eyes. Will never go back to using a stick. Just buy a decent MIG and use the correct gas for the material. I have a 180amp welder using Argoshield Universal and 0.8 wire. r |
