5 Inductance Control

Inductance determines the “wetness” of the weld puddle. When set higher, “wetness” (puddle fluidity) increases.

5-2. Mode And Voltage Control For CV Only Models

	1 Remote 14 Receptacle
	Mode Control
	The unit defaults to standard MIG
	mode.
	Pulsed MIG welding requires that
	an external pulsing control be con-
	nected to the Remote 14 recep-
	tacle. The remote pendant controls
	whether the unit is in standard MIG
	or pulsed MIG mode. When the
	pulsing control is disconnected, the
	unit returns to standard MIG opera-
	tion.
	Voltage Control
	The unit defaults to Panel control of
	output voltage. When a suitable re-
	mote voltage control or pulsing con-
	trol is attached to the Remote 14 re-
	ceptacle, the remote device as-
	sumes control of output voltage.
	To return to Panel control of voltage,
	disconnect or disable any remote
1	devices that send an input to pin E.
