WebThe usual cause is poor shielding coverage, rather than an unclean joint or equipment. The correct gas flow rate for gas tungsten arc welding (GTAW) is 15 to 30 cubic feet per hour (cfh), or 7.08 to 14.16 liters per minute (lpm) (or a 2-to-1 ratio). Often, welders set their gas flow higher in the mistaken belief that it will make for a purer weld.
