1 INTRODUCTION
1.1 Mode of operation -- Control box
The control box consists of four memory units, the working area, the
library, the notebook and the auxiliary function.
S In the working area the welding program is created.
S In the library the program can be stored.
During welding it is always the contents of the working area that control
the welding process. Thus it is also possible to call in a welding program
from the library to the working area.
S In the notebook you can make your own notes about special welding
parameters, for example.
S In the auxiliary function you can:
S change languages
S view all existing error messages
S show actual parameter values
S software upgrade
S sofware key
1.2 Sectors
A welding program for welding of tubes can be divided into different parts or
sectors. Each sector corresponds to a special part of the circumference of
the tube. Max. number of sectors for one program is one hundred (100).
Sector 1
Sector 2
Sector 4
Sector 3
A sector can be assigned its own set of values for different welding
parameters, such as current, rotation speed, wire feed speed, etc. In this
way the welding can be performed using different parameter settings for
different parts of the joint of the tube.
-- 5 --
dpa8d1ea
The division into sectors is done by indicating different breakpoints along
the circumference of the tube. Each such breakpoint constitutes the
starting point of a new sector. In the figure below, the breakpoint 0.000 is
the starting point of sector 1, breakpoint 0.250 the starting point of sector 2,
etc.
Sector 1
Sector 2
Sector 4
Sector 3
Breakpoint 0,000
Breakpoint 0,250
Breakpoint 0,500
Breakpoint 0,750
LTS 320 allows welding of up to 10 turns in the same welding joint, i.e. the
welding tool can be rotated 10 times round the tube.
The breakpoints in the previous figure all start with the integer 0 which
means that they form the breakpoints of turn 1. The breakpoints of turn 2
(if there is one) always start with the integer 1,etc.
S T urn 1 = breakpoints 0.000 -- 0.999
S T urn 2 = breakpoints 1.000 -- 1.999
S T urn 3 = breakpoints 2.000 -- 2.999
S T urn 4 = breakpoints 3.000 -- 3.999
S T urn 5 = breakpoints 4.000 -- 4.999
S T urn 6 = breakpoints 5.000 -- 5.999
S T urn 7 = breakpoints 6.000 -- 6.999
S T urn 8 = breakpoints 7.000 -- 7.999
S T urn 9 = breakpoints 8.000 -- 8.999
S T urn 10 = breakpoints 9.000 -- 9.999
To terminate a welding program a so--called end sector is indicated.
For a sector to be counted as an end sector the following two conditions
must be fulfilled:
S There is no sector following.
S The welding current value of the sector = 0 ampere.

SHIFT key
This key is used for changing the significance of other keys on the
keyboard.

SLOPE
This key is used when you want to add a slope function to a parameter and
is indicated in the following way in the display
.
By slope is meant a gradual change of a set value.
Slope up = gradual increase
Slope down = gradual decrease
The following parameters can be assigned a slope function:
-- 1 0 --
dpa8d1ea
Current (both peak and background current) when pulsed current is used,
rotation, wire feed speed.
A slope can be time--controlled by indicating that it shall go on for a certain
number of seconds. It can also be sector--controlled, making it a so--called
sector slope, by indicating between which two breakpoints it shall be
located.
SECTOR
This key indicates the breakpoint of a program and moving to indicated
sector.

This key is used for stepping forward in the program.
DELETE
This key is used for deleting the whole program, part of a program in the
working area, or just the figures in the digit box.

2 WELDING PARAMETERS
Setting ranges for the welding parameters can be found in the APPENDIX
on page 95.
2.1 Weldin g current
There are four different parameters for welding current:
S PEAK CURRENT
S BACKGROUND CURRENT
S PEAK TIME (1 s)
S BACKGROUND TIME (1 s)
The values in brackets are preset values.
Peak time
Background time
Background current
Peak
current
The welding current can be either pulsed or continuous (not pulsed).
If you want to weld using pulse current a value must be entered for all four
parameters. When welding with continuous current, however, you only need
to enter the value for peak current. Entering a value also for background
current will result in pulsed current with preset pulse and background
times. Of course, the pulse and background times can also be changed.
-- 1 3 --
dpa8d1ea
2.2 Gas
In the Shielding Gas parameter group three parameters are represented:
S WELD GAS
S ROOT GAS
S START GAS
By weld gas is meant the shielding gas on the upper side of the joint. The
weld gas parameter indicates the time the shielding gas is to flow on the
upper side of the joint before and after welding.
The values of the weld gas parameter are preset. The following values for
preflow and postflow of the weld gas apply at the start if nothing else has
been indicated:
S Weld gas preflow = 2 s
S Weld gas postflow = 4 s
By root gas is meant the shielding gas on the underside of the joint. The
root gas parameter indicates the time the shielding gas is to flow on the
underside of the joint before and after welding.
Some shielding gases, for example helium (He), can cause difficulty with
regard to striking the arc. If such a shielding gas is to be used as weld gas,
it could be advisable to use another gas mixture at the start moment -- a
so--called start gas.
If one value is entered for weld gas in sector 1 and one for start gas, only
the start gas is going to flow. The weld gas starts flowing when the arc is
struck.
2.3 Wire feed speed
This parameter is used to indicate the desired feed speed of the filler wire in
cm/min.
The wire feed speed can be pulsed or continuous (not pulsed).
In the Wire Feed Speed parameter group two parameters are represented:
-- 1 4 --
dpa8d1ea
S PEAK WIRE FEED SPEED
S BACKGROUND WIRE FEED SPEED
For welding with continuous (not pulsed) wire feed speed, only the peak
wire feed parameter shall be entered.
For welding with pulsed wire feed speed, both the peak wire feed speed
and the background wire feed speed parameters shall be entered.
The pulsed wire feed speed is always automatically synchronised with the
welding current. The wire feed speed is high using pulse current and low
using background current.
2.4 Preheatin g time
Preheating is used for heating the workpiece at the starting point in order to
obtain correct penetration of the molten pool. The preheating time is defined
as the time elapsing between arc strike and start of the rotary motion. If no
value has been entered for the preheating parameter , the arc will strike at
the same time as rotation is started.
NOTE! In the Welding Current parameter group you cannot indicate a
sector slope when preheating is involved.
2.5 Rotation speed
This parameter indicates the rotation speed of the electrode round the
workpiece. It is indicated in per mill (thousandths) of the max. rotation speed
of the welding tool used.
Just like welding current and wire feed speed, the rotation speed can be
pulsed or continuous (not pulsed).
In the Rotation Speed parameter group four parameters are represented:
S ROTATION FORWARDS
S ROTATION BACKWARDS
S PULSED ROTATION FORWARDS
S PULSED ROTATION BACKWARDS
The pulse rotation is always automatically synchronised with the welding
current. The welding tool rotates when peak current is used, and stands still
when background current is used.
-- 1 5 --
dpa8d1ea
3 START AND STOP
3.1 Start
To start the welding, use the START key .
It is impossible to start a welding program if another tool code has been
indicated than the one used in the program in question.
3.2 Stop
A requested welding stop over the STOP key means that the program
jumps to the following end sector, no matter which sector you are in at the
moment. The welding is terminated according to the settings of the end
sector.
A requested welding stop over the DIRECT STOP key
leads to
immediate stop of the welding. The gas postflow takes place according to
the time set in the end sector.
3.3 Restart
If the welding was interrupted it is restarted with the SHIFT and START
keys
.
Irrespective of whether the welding was stopped over the STOP
or the DIRECT STOP key , the start parameters of the preceding
start sector are used. The program then continues from the position in the
welding program where it was interrupted.
-- 1 6 --
dpa8d1ea
4 TO GET STARTED
4.1 Gen eral
Some of the factors controlling the welding process are specific to each one
of the welding tools, for example the rotation speed. Therefore, every
welding program must be connected to a tool code, associated with the
tool that the program was made up for.
4.2 How to indicate a tool code
S T urn the mains switch on the welding power source to position 1.
S The following display comes up:
