hi there. i have a XMT 304 (a very popular unit over these parts) 24A feeder and optima control, i use this set all the time but unfortunately not the optima in pulse mode as i just cant get the results i want. i am welding stainless 304 1.5 to 5 mm. can you give any advice for pulsing set up, any idea's as about wire size and speed and programme settings, any info would be much appreciated, Neal (Ireland and England)
