  • pre and post flow

    My s64 feeder does not have pre and post flow nor run in adjustments. How important are these "optional" features in mig? I know that it is important to have pre and post flow in tig welding.

      The 30A spool gun will allow you to pre or post flow by only releasing or pushing the trigger part way. I use post flow at times to cool my tack welds on thin sheet metal.

        You may want pre-flow when MIGing aluminum. That's a nice feature of the 15A and 30A - two stage trigger.

        Be well.
