2-9. Shielding Gas Connections

		Y Turn Off power before con-
			necting to receptacle.
	4	1	Gas Valve In Fitting
		Fitting has 5/8-18 right-hand
		threads.
Tools Needed:	3	Located on rear of unit.
5	3	Located on rear of unit.
5/8, 1-1/8 in		2	Gas Valve Out Fitting
		2	Gas Valve Out Fitting
		Gas connection is integrated into
		the Electrode weld output terminal
		by means of a flow-through type
		connector.
		3	Cylinder Valve
		Open valve slightly so gas flow
		blows dirt from valve. Close valve.
		4	Regulator/Flow Gauge
		Connect regulator/flow gauge to
		gas cylinder.
	1	Connect gas hose to gas in fitting.
		5	Flow Adjust
		Typical flow rate is 20 cfh (cubic feet
2		per hour).
