Miller Electric PipePro Dual Range Locks, Wire Feed Speed Units, Software Revision Level, Code

Range Locks

Range locks are indicated by “LOCK” in the upper display for wire speed or “LOCK” in the lower display for voltage range.

In a MIG program, the voltage range lock ranges from +/− 0 to 10 volts.

In a pulse program, the trim range lock ranges from +/− 0 to 100.

The wire speed range lock ranges from +/− 0 to 195 IPM.

Locks are program dependent and wire speed locks are independent from voltage/ trim command locks (i.e. you can have a wire speed lock with or without locking the voltage/trim command and vice versa).

Press the Upper Display Pushbutton to se- lect Voltage/Trim Command Range Locks.

Press the Lower Display Pushbutton to se- lect Wire Speed Range Locks.

To set a Voltage/Trim Command Range Lock, you must choose the type of com- mand being locked, voltage or trim based on the type of weld process selected at the power source. This is done by repeatedly pressing the Upper Display Pushbutton to cycle between OFF, T (trim) or V (voltage), as indicated on the Upper Display.

Use the adjust knob to set the range value.

Once any program has a lock enabled, the remaining programs with all locks “OFF” will not be accessible. To enable additional programs, set the lock values for one or more Voltage/Trim Command or Wire Speed to appropriate ranges for each pro- gram.

Only one of the values needs to be set to enable the program. For example, setting a Trim of 100 and leaving the Wire Speed at OFF will allow the welder to adjust the Wire Speed to full range

Wire Feed Speed Units

Wire feed speed setting indicated by “WFS” in the upper display is set to “IPM” inches− per−minute or ”MPM” meters−per−minute. This setting is independent of the program selected.

Software Revision Level

•The unit displays the software version being used by the interface PCB (PC20).

•When the Setup button is pressed again, the menu repeats.

Code

Upon leaving the auxiliary menu, the user is asked if a password code, indicated by “CODE” in the top display should be acti- vated.

By default the code is “OFF” in the lower display. The user may enter a numerical

password between 0 and 999 by turning the Adjust control.

If a code is set, when the user re-enters the auxiliary menu, the password code must be selected to gain access to the auxiliary menu. Press Setup and Sequence buttons simultaneously to enter the auxillary menu. A failed attempt returns the user to the weld screen and a counter is incremented. A counter in the program display shows the number of incorrect attempts. The user has five attempts to enter the correct password code before being locked out of the auxilia- ry menu, indicated by “LOCK” in the lower display.

The power may be cycled to continue weld- ing, but the user will remained locked out of the auxiliary menu.

The counter can be reset in the weld screen by pressing the Program, Sequence, upper display, and Set-up push buttons simulta- neously. Resetting the counter is indicated by “CODE” in the upper display and “RSET” in the lower display. Pressing the Program, Sequence, upper display, and Set-up push buttons simultaneously again resets the counter to 0.

To reset the password, follow the directions under Reset To Factory Settings at the be- ginning of this section. Note: this will reset all settings and programs to the factory de- faults.
