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 operator has INSTALLED
the M-207A per section III and has a good understanding of functions from
section IV. Function explanations are not covered in this section.
The M-207A uses two displays 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-207A TRAINING CLASS.

power ON MAKE SURE THE INPUT POWER SET UP IS CORRECT
FOR THE POWER BEING USED.
