I have been doing a lot of GMAW-Pulse at my school lately and I have yet to get a good grasp of how to set the machine up. We have a 70 series feeder hooked up to a XMT-304 with a bernard Q-gun. i am welding on 3/8" plate with 90% Ar/ 10% Co2. So far i have found that about 225 wire speed and trim of about 30 and arc length of 11 work pretty good. My teacher is also unfamiliar with pulse, so hes not much help Still a good teacher tho.
Thanks in advance for any advice!
