Complete Parts List is available at www.MillerWelds.com
Description
Arc Timer: Monitors hours, minutes, and cycles of valid arc on. To view, rotate amperage adjustment con-
trol. To reset, rotate amperage adjustment control until [RESET] [YES] is displayed. Press Menu button to
display [RESET] [Done]. Displays turn to [000] [000].
Error Log: Use to view last eight logged error events. Each event may list multiple Error Codes. See Sec-
tion 11-5.
Sleep Timer: Turns power off after the machine exceeds the programmed idle time without operation.
Press the Standby button to turn power on. To set or change time, rotate amperage adjustment control to
desired time. Timer range: 1, 5, 10, 20, 30, 45 minutes or one hour.
Stick Stuck: Detects if the electrode is stuck or shorted to the workpiece. Turns weld output off to aid in
freeing the electrode. To turn on, rotate amperage adjustment control. Not recommended for air carbon
arc or large diameter electrodes.
Open Circuit Voltage: Allows user to select between Normal [NORM] and Low open circuit voltage. Low
reduces open circuit voltage to between 8 and 15 volts. To select, turn amperage adjustment control.
�
Optional - OCV selection can be made while in the V-Sense Feeder (DC MIG) process also applies.
Weld Timers: [ON] enable and [OFF] disable the feature. See Section 10-3for information on setting weld
timers. Weld Timers work with or without Sequencer feature.
Cooler Power (Optional): Selects between [OFF], [ON] (Non CE models Only), and [AUTO]. [OFF] dis-
ables the power supply to the receptacle. [ON] enables the power supply to the receptacle. [AUTO] pro-
vides power to the receptacle when the TIG process is active.
Limits user control and adjustability of machine. See Section 10-5 for instructions and operation.
Meter Display while welding and preset amperage, with pulser on, meters can be set to display the
following:
[V/A] - Welding: average voltage and amperage
Preset: peak amperage A complete Parts List is available at www.MillerWelds.com
[OFF] - Welding: [PULS] [WELD]
Preset: peak amperage
[AVG] -Welding: average voltage and amperage
Preset: average amperage
External Pulse Control Commands: Turn on when it is desired to control machine from an external
source. When command is on, a command voltage of 0 - 10 volts DC equals off - 280 amps.
Machine Reset: Resets all machine values back to factory defaults. To reset, turn amperage adjustment
control to [RESET] [YES]. Then press Menu button. [RESET] [DONE] will be displayed when the reset is
complete and factory defaults have been restored.
Software Number: Software number and revision will be displayed.
Serial Number: If serial number displayed does not match serial number of machine, see Section 11-5.
Sequencer Control With Weld Timers ON
This function is available while using the TIG process, but is disabled if a remote foot or fingertip con-
trol is connected while in the RMT STD mode. When active, the sequencer controls the following pa-
rameters of the weld cycle:
Parameter/Setting
Display Example
[INTL] [20A] Initial Amperage: Range is 2–280 amps AC, 1–280 amps DC.
[INTL] [OFF] *Initial Time: Range is OFF to 25.0T (seconds).
[ISLP] [OFF] Initial Slope Time: Range is OFF to 50.0T (seconds).
[FSLP] [OFF] Final Slope Time: Range is OFF to 50.0T (seconds).
[FNL] [10A] Final Amperage: Range is 2–280 amps AC, 1–280 amps DC.
[FNL] [OFF] *Final Time: Range is OFF to 25.0T (seconds).
�
[WELD] [OFF] Weld Timer: With Weld Timer enabled, press Amperage (A) button, and ro-
tate amperage adjustment control to set weld time. Range is Off or 0.1-99.9
and 100-999 (sec) (see Section 10-2).
*Enabled features with weld timer On (see Section 10-2).
Description
When a remote switch is connected to the welding power source, use
the remote switch to control the weld cycle. Amperage is controlled by
the welding power source.
