Watched a video on MIG welding in which a grease material was suggested to be used on the nozzle interior and the tip end, to minimize crud buildup and make cleaning easier. Have read my M211 manual and do not find any reference to MIG grease or anything similar. Is this a needed practice that is learned later after getting nozzles and tips cruded up, or is this some new fangled stuff just looking for an application? Searched this forum and found nothing on the subject, so I quit there and am now asking the experts.
Thanks for any comments,
