Operation Manual
SECTION V - OPERATION
5.0 INTRODUCTION
Operation covers those steps that must be taken to actually perform a weld. Programming and
development of schedules are not covered in this section. It is very important to insure, before
operating, that the operators have INSTALLED the M-415 per section 3 and that they have a good
understanding of functions from section 4. Function explanations are not covered in this section.
The M-415 uses a 640 by 480 Color VGA LCD Touch screen display to provide information and
instructions for use. For the most part, the information and instructions presented on these
displays are adequate explanation of operation. This section is only intended as a guideline to get
started with for first time users AFTER HAVING ATTENDED AN AMI M-415 TRAINING CLASS.
5.1 INITIAL POWER ON/LOGO SCREEN
1. Before connecting or energizing the AC power; verify that all input power set up and
installation requirements of Section 3 of this manual have been complied with.
WARNING
MAKE SURE THE INPUT POWER SET UP IS CORRECT FOR THE POWER BEING USED.
2. The M-415 can be turned on without the adapter cable, gas hoses or weld head connected.
However, to verify proper operation they must be connected. Insure that all of these
connections are per section 3.
3. Plug in the AC power cable to the AC source. Move the circuit breaker (CB-1) to the ON
position.
4. After a few seconds the LOGO SCREEN will appear as shown in Figure 4. From this
screen all system operations will begin.
NOTE
If the input power is too low it is possible for the screens not to turn on or be scrambled.
If these conditions occur recycle CB-1. If they continue to occur check the input power and
the power setup of the M-415.
5.2 POWER SUPPLY CALIBRATION INTRODUCTION
The following M-415 Power Supply calibration procedure is intended for calibration and certification
of system performance by the user. Except Current and AVC Servos all system operations are
controlled by microprocessor and do not require field calibration. Any time repairs or replacements
are done to the Current servo, AVC, or reference voltage PCB, calibrations must be checked. It is
also good practice to check calibration after shipping from one location to another.
WARNING
All personnel attempting to calibrate, trouble-shoot, or repair this power supply must be familiar with
its operation. They must understand the circuits and have a complete understanding of their controls
and interrelationships. Components in these circuits are static sensitive, basic electronic procedures
must be followed to prevent handling damage!
