EXCEL ARC 6045 OPERATION
Manual 0-5213 4-6 August 26, 2011
4.06 GTAW (TIG) Welding
1. Connect the work lead to the POSITIVE OUTPUT
RECEPTACLE.
2. Connect the TIG torch lead to the NEGATIVE OUTPUT
RECEPTACLE.
3. Set MODE SELECTOR SWITCH (SW2) to TIG position
(GTAW - CC).
4. Turn the ON/OFF SWITCH (SW1) to ON position.
a. Connect remote to J1 Connector.
5. When using a Remote Potentiometer to control the
output current:
a. Set the VOLTAGE / CURRENT CONTROL
POTENTIOMETER (R1) to select the maximum
current level for the remote.
b. Set LOCAL / REMOTE SWITCH (SW4) to REMOTE
position.
If no remote current control is to be used:
a. Set LOCAL / REMOTE SWITCH (SW4) to LOCAL
position.
b. Set the VOLTAGE / CURRENT CONTROL
POTENTIOMETER (R1) to select the desired
welding current.
6. Position the torch for welding.
7. Touch the electrode to the work piece, activate the
Remote OUTPUT ON (CONTACTOR ON) signal, then
lift the electrode off from the plate and the welding arc
will initiate.
8. When finished welding, deactivate OUTPUT ON
(CONTACTOR ON) signal.
NOTE
Welding will not start in GTAW mode without a
Remote OUTPUT ON (CONTACTOR ON) signal.
4.07 GMAW / FCAW with Constant Speed
Wire Feeder
1. Complete all Wire Feeder and MIG Gun connections.
2. Turn ON/OFF SWITCH to ON position.
3. Set MODE SELECTOR SWITCH (SW2) to MIG position
(CV GMAW / FCAW).
4. VOLTAGE CONTROL.
If using a wire feeder with remote voltage control:
a. Set the VOLTAGE / CURRENT CONTROL
POTENTIOMETER (R1) to set the maximum
voltage level for the remote.
b. Set the LOCAL / REMOTE SWITCH (SW4) to
REMOTE position.
If using a wire feeder without remote voltage control:
a. Set LOCAL / REMOTE SWITCH (SW4) to LOCAL
position.
b. Set the VOLTAGE / CURRENT CONTROL
POTENTIOMETER (R1) to desired voltage level.
5. Position the MIG Gun for welding and close gun switch
and start welding.
4.08 GMAW / FCAW with Voltage Sensing
Wire Feeder with Contactor
1. Complete all Wire Feeder and MIG Gun connections.
2. Turn ON/OFF SWITCH (SW1) to ON position.
NOTE
The output enable LED (green) will be on at
this time and there should be output at the (+)
and (-) terminals.
3. VOLTAGE CONTROL.
If using a wire feeder with remote voltage control:
a. Set the LOCAL / REMOTE SWITCH (SW4) to
REMOTE position.
b. Set the VOLTAGE / CURRENT CONTROL
POTENTIOMETER (R1) to set the maximum
voltage level for the remote.
If using a wire feeder without remote voltage control:
a. Set LOCAL / REMOTE SWITCH (SW4) to LOCAL
position.
b. Set the VOLTAGE / CURRENT CONTROL
POTENTIOMETER (R1) to desired voltage level.
4. Position the MIG Gun for welding and close gun switch
and start welding.
