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-227 per section III and has a good understanding of functions from section IV.
Function explanations are not covered in this section.
The M-227 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-227 TRAINING CLASS.
5.1
INITIAL POWER ON/STATUS SCREEN
1. Before connecting or energizing the AC power; verify that all input power
set up requirements of Section III have been complied with.
WARNING
Applying 200 VAC or greater input power to a M-227 set up for 110 VAC
operation WILL CAUSE THE INPUT VARISTERS TO FAIL. MAKE
SURE THE INPUT POWER SET UP IS CORRECT FOR THE POWER
BEING USED.
2. The M-227 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 III.
3. Plug in the AC power cable to the AC source. Move the circuit breaker
(CB1) to the ON position.
4. After a few seconds the STATUS SCREEN will appear as shown on the
next page:
NOTE
If the input power is too low it is possible for the screens not to turn on,
be scrambled or get a fault screen indicating a LVPS fault. If these
conditions occur recycle CB1. If they continue to occur check the input
power and the power setup of the M-227.
