SECTION IV - SYSTEM FUNCTIONS
4.0 INTRODUCTION
The M-415 is intended for use with AMI orbital welding heads and has functions designed for
these weld heads. This section describes what these functions are and may, where needed for
clarification, indicate how they are commonly (but not always) used.
Only FUNCTION is discussed here. Details of function ranges and tolerances can be found in
section II of this manual and the AMI Specification No. 415.
4.1
MULTI-LEVEL FUNCTIONS and MODES
Most M-415 functions have the ability to be programmed to change during a weld sequence.
This change of parameters is contained with in LEVELS. The M-415 provides up to 100 levels
for the following functions and modes.
1.
PRIMARY CURRENT
- Sets the value of current in each level during the PRIMARY
PULSE
time.
2.
BACKGROUND CURRENT
- Sets the value of current in each level during the
BACKGROUND PULSE time.
3.
PRIMARY PULSE TIME
- Sets the length (time) for primary pulse functions.
4.
BACKGROUND PULSE TIME
- Sets the length (time) for background pulse functions.
5.
PULSE MODE
OFF
- Provides continuous functions only, no pulsing, primary values only
ON
- Pulses from primary to background based on the PULSE TIME settings.
SYNC
- Synchronizes the pulsing to the OSC movement. Dwell times are primary and
Excursion time is background
EXT
- Will pulse from primary to background based on an external timing signal.
6.
LEVEL MODE
AUTO
- Uses Level time to determine when to switch to the next level.
MANUAL
- Levels switch only from Pendant command manually made by operator.
POSITION
- Allows levels to advance based on weld head position in degrees or inches.
EXT
- Allows levels to advance based on an external input signal.
7.
LEVEL TIME
- Sets the time each level will be used before advancing to the next level if
LEVEL MODE is set to AUTO..
8.
LEVEL POSITION
- Set the position in degrees or inches that will determine when the levels
will change if LEVEL MODE is set to POSITION.
9.
PRIMARY TRAVEL SPEED
- Sets the Travel Speed value in each level during the
PRIMARY PULSE time.
10.
BACKGROUND TRAVEL SPEED
- Sets the Travel Speed value in each level during the
BACKGROUND PULSE time.
11.
TRAVEL STEP MODE
ON
- Allows the System to pulse between the PRIMARY TRAVEL and the BACKGROUND
TRAVEL.
OFF
- Travel moves continuously at the primary rate regardless of pulsing or pulse mode.
12.
PRIMARY WIRE FEED SPEED
- Sets the Wire Feed value in each level during the
PRIMARY PULSE time.
13.
BACKGROUND WIRE FEED SPEED
- Sets the Wire Feed value in each level during the
BACKGROUND PULSE time.
14.
WIRE PULSE MODE
OFF
- Wire Feed is continuously the Primary value regardless of pulse mode.
ON
- Wire Feed will pulse from Primary to Background values based on the pulse
mode time.
15.
PRIMARY AVC
- Sets the Arc Voltage value in each level during the PRIMARY
PULSE
time.
