4 Dependent on the capabilities of the ArcReach power source, the feeder may set the mode switch to the correct wire mode. The wire mode is
determined by the polarity of the connections to the feeder.
5 Use voltage control on feeder to adjust preset weld voltage.
6 The voltmeter on the feeder will display preset weld voltage while idle or weld voltage while welding.
Associating wire feeder to an ArcReach compatible welding power source or ArcReach Control when the wire feeder is triggered
�
The welding power source must be in an Output On mode. See instructions in the welding power source Owner's Manual.
�
On wire feeder, set CC/CV switch to CV mode. The feeder will not associate with another piece of equipment if the feeder is set to CC
mode.
1 Turn on the welding power source and wire feeder. The wire feeder voltage display will alternate between three dashes and open circuit
voltage.
2 Pull trigger on gun. Do not strike an arc.
3 Decimal points on feeder voltmeter will blink.
4 When decimal points stop blinking and a voltage is displayed, the feeder and power source or ArcReach Control are associated. Release trig-
ger on gun. The association process may take several seconds to complete.
5 Dependent on the capabilities of the ArcReach power source, the feeder may set the mode switch to the correct wire mode. The wire mode is
determined by the polarity of the connections to the feeder.
6 Use voltage control on feeder to adjust preset weld voltage.
7 The voltmeter on the feeder will display preset voltage while idle or weld voltage while welding.

Equipment Setup
�
To take advantage of the ArcReach features, the ArcReach wire feeder must be used with an ArcReach Control, or an ArcReach compati-
ble welding power source. The ArcReach wire feeder may also be used as a standard feeder on any Non-ArcReach power source.
During ArcReach operation, weld voltage and wire feed speed are set at the wire feeder front panel. Voltage control is disabled at the welding
power source.
Using the ArcReach wire feeder with an ArcReach compatible welding power source or ArcReach Control
1 For the wire feeder to control the welding power source, the wire feeder and power source, or wire feeder and ArcReach Control must be as-
sociated. If the wire feeder is not associated to the welding power source or ArcReach Control, the wire feeder will try to associate to a weld-
ing power source or ArcReach Control when the trigger is pulled. See Section 5-4 to associate the wire feeder to an ArcReach compatible
power source or ArcReach control.
2 When association is complete, the voltage display on the wire feeder will display preset voltage. The preset voltages of the wire feeder and
the welding power source should be within 0.5 volts of each other.
3 While adjusting the voltage control on the feeder, the voltage display will show preset voltage.
4 While welding, the welding power source will display weld voltage at the studs of the welding power source. The wire feeder displays weld
voltage at the wire feeder.
5 While welding, due to the voltage drops in the weld cable, the voltage display at the wire feeder and the voltage display at the welding power
source will not match. The preset voltage at the wire feeder must be set to a higher value to compensate for the voltage drop of the weld ca-
ble. Example: if welding voltage of 18 volts is desired at the wire feeder and there is a 4 volt drop in the weld cable, the preset voltage at the
wire feeder should be 22 volts (18V + 4V = 22V).
6 When the wire feeder and welding power source or ArcReach Control are associated, they will stay associated until either unit is turned off.
The wire feeder can lose power for up to ten seconds and still recover its association with the welding power source or ArcReach Control.
This is for situations where the wire feeder may momentarily lose power due to a prolonged short circuit condition in the welding process.
7 If the CC/CV switch on the feeder is changed to CC mode, the feeder will lose its association with the welding power source or ArcReach
Control. To re-establish the association, set switch to CV mode and restart the association process.
Using the ArcReach wire feeder with a Non-ArcReach compatible welding power source
1 The wire feeder may be used with any constant voltage (CV) or constant current (CC) DC welding power source.
2 Set CC/CV switch in feeder to match output of power source.
3 The wire feeder will automatically work on a non-ArcReach compatible welding power source. There are no switches or jumpers to change.
4 The ArcReach features will not be available.
5 The voltage knob on front panel will be non-functional.
6 If the feeder is set to CC, the voltage display on the wire feeder will display CC when not welding.
7 While welding, the voltage display on the wire feeder will display weld voltage at the wire feeder.
