<strong>[QUOTE]Also try the different polarity and/or AC settings to change the heat going into the metal (if your welder supports this). Reversing the polarity (make the electrode negative) will greatly reduce the heat into the metal, and running AC is about 1/2 way between the two. This is the main advantage of having an AC/DC welder, gives you added flexibility.</strong></font><hr /></blockquote><font size="2" face="Verdana, Tahoma, Arial, Helv, Helvetica, Sans">Roger, is this true for MIG welding as well?</strong></font><hr /></blockquote><font size="2" face="Verdana, Tahoma, Arial, Helv, Helvetica, Sans">Unfortunately no, MIG (gas or flux core) have to be run the proper polarity, hard wire is electrode-positive and flux core is usually electrode negative.
