Proper Grounding - Be sure to always connect the workpiece to a proper earth ground. Connect the frames of electrically powered machines to a properly grounded disconnect switch, receptacle or other appropriate ground. Always double-check the installation and verify proper grounding.
Power Cable - When installing a replacement power cable ALWAYS use a conductive sealant on the threads to insure maximum weld current transfer.
Changing Spool of Wire - Blow out the conduit every time you change a spool of wire.
Aluminum, Doesn’t Look Hot - Welders always carry soapstones or a piece of chalk... in order to write the word ‘HOT’ on or around a recently welded piece of metal, that in the case of aluminum, doesn’t always look hot.
Measure Wire Feed Speed - For GMA Welding, to measure wire feed speed in the field on equipment without a digital display; reduce pre-purge time to zero and turn off PosaStart, hold trigger to measure out wire for 6 seconds, multiply the measured length of wire by 10 (length x 10 = wire feed speed) to estimate the IPM.
