Class 2 IP67 Enclosed Switching Power Supply - Output Current Adjust by Output Cable, 48VDC 840mA 40W

hi welcome to lunch Ares Learning Lab today I'm going to talk about C C and C V constant voltage and constant current what are the differences why are they different why do we need both of these different current settings in the welding processes so stick welding SMAW shielded metal arc welding and TIG welding gas tungsten arc welding were developed long before MIG welding yes metal arc gmaw yes metal arc welding so the power supply for these two types of welding were constant current that's what was needed that was the power supply for these two as they developed and so constant current was just the standard for the way that these two processes were developed in stick welding and NT welding the operator may you are is controlling the electrode and so this is long arcing this is short arcing and so we're controlling the amperage slightly but what we're definitely impacting is voltage as
