Prepare unit for Stick welding as follows:
Connect electrode holder to positive
weld output receptacle.
Connect work clamp to negative weld
output terminal.
If desired, connect a remote control to the
remote control receptacle.
Turn power on. Allow time for unit to com-
plete its start up cycle.
Press and release Process/Set-Up Ad-
justment control to select Stick welding
and light corresponding LED. Display
meter displays ARC for three seconds
and then the factory default setting of 80
amperes.
Voltage Reduction Setting
To change voltage reduction setting, pro-
ceed as follows:
Press and hold Process/Set-Up Adjust-
ment Control to enter set-up mode.
Upon entry, the Set-Up light begins to
flash, and the display meter displays
VRD.
Voltage Reduction default is Off. Use
Amperage/Set-Up Adjustment control to
enable or turn setting On.
When Voltage Reduction is enabled,
Stick Welding light flashes continuously.
VRD is set to 20 volts.
.
Unit will automatically exit the set-up
menu if no activity is detected for
more than three seconds. Press and
hold Process/Set-Up Adjustment
control to re-enter set-up mode.
Hot Start Setting
Use Hot Start to increase output amper-
age at the start of a weld to help prevent
electrode sticking.
To change Hot Start setting, proceed as
follows:
While in the set-up menu, press and re-
lease Process/Set-Up Selector switch.
The Set-up light continues to flash.
The display meter will display HS.
Use the Amperage/Set-Up Adjustment
control to change amperage from 0 to 50
percent of the preset amperage value,
with 15 percent being the default value.
The maximum Hot Start amperage value
is 150 amps.
Example: If preset amperage is 90 amps,
0% = 90 amps, 50% = 135 amps.
Arc Force Setting:
Use Arc Force to increase short-circuit
amperage at low arc voltage. Set at 0 for
normal welding amperage. Turn control
clockwise to increase short-circuit am-
perage.
To change Arc Force setting, proceed as
follows:
While in the set-up menu, press and re-
lease the Process/Set-Up Selector
switch. The Set-Up light continues to
flash.
Use the Amperage/Set-Up Adjustment
control to change amperage from 0 to 50
percent of the preset amperage value,
with 15 percent being the default value.
The maximum Arc Force setting is 150
amps.
Example: If preset amperage is 90 amps,
0% = 90 amps, 50% = 135 amps.
Anti Stick
Anti Stick prevents the electrode from
sticking while welding.
This function is automatically active while
using the Stick welding process. Anti
Stick increases amperage when arc
voltage is below ten volts for more than
two seconds.
.
The amperage range while Stick
welding is from 4 to 150 amps.
