1 INTRODUCTION
1.1 Mode of operation -- Control box
The control box consists of four units, the working area, the library, the notebook
and the auxiliary functio n.
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 fun ctio n 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.
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
GB
-- 5 --
dpa8d1ea
LTP 450 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 th e integer 1,etc.
S Turn 1 = breakpoints 0.000 -- 0.999
S Turn 2 = breakpoints 1.000 -- 1.999
S Turn 3 = breakpoints 2.000 -- 2.999
S Turn 4 = breakpoints 3.000 -- 3.999
S Turn 5 = breakpoints 4.000 -- 4.999
S Turn 6 = breakpoints 5.000 -- 5.999
S Turn 7 = breakpoints 6.000 -- 6.999
S Turn 8 = breakpoints 7.000 -- 7.999
S Turn 9 = breakpoints 8.000 -- 8.999
S Turn 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.

2 WELDING PARAMETERS
Setting ranges for the welding parameters can be found in the APPENDIX on page
76.
2.1 Weld ing 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.
GB
-- 1 0 --
dpa8d1ea
The welding current (pulsed current) can be synchronised with the weaving motion
so that the peak current will set in when the electrode is in the extreme positions of
the weaving motion. This is called special pulsin g.
(The peak current sets in at the extreme weaving positions also when special pulsing
is not used.)
Special pulsing
By special pulsing is meant that the welding current is synchronised with the weaving
motion, i.e. you get peak current when the electrode is in an end position of the
weaving motion. Thus the peak current time is determined by the dwell time of the
respective dwell position.
Special pulsing can be used in combination with both continuous and pulsed
rotation. Special pulsing with pulsed rotation -- also called square--wave pulsing --
means that the gear ring rotates when the electrode is in an end position of the
weaving m otion.
Special pulsing with
continuous rotation
Rotation direction
Special pulsing with
pulsed rotation

A = background current B = peak current
As to special pulsing, the wire feed can be either continuous or pulsed. As to pulsed
wire feed, the synchronisation with the welding current takes place in the way
described above, see the section βWire Feed Speedβ on page 11.

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. T he weld gas starts flowing when the arc is struck.
2.3 Wire feed speed
This param eter is used to indicate the desired feed speed of the filler wire in cm /m in.
The wire feed speed can be pulsed or continuous (not pulsed).
In the Wire Feed Speed parameter group two param eters are represented:
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.
GB
-- 1 2 --
dpa8d1ea
2.4 Preheating 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 a s r otation
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
Pulsed rotation is automatically synchronised with the welding current so that the
welding tool stands still when the peak current sets in and rotates during background
current.
2.6 Arc voltage control (AVC)
This parameter is used for automatic control of the arc when welding with a tool fitted
withanAVCunit.
Arc voltage control (AVC) means that the arc voltage, and by that the length of the
arc (i.e. the distance between the tip of the electrode and the workpiece), is
automatically controlled in the course of welding.
In the Arc Voltage Control (AVC) parameter group three parameters are represented:
S PEAK VOLTAGE (Arc voltage when using peak current)
S BACKGROUND VOLTAGE (Arc voltage when using background current)
S DELAY TIME
With the parameters peak voltage and background voltage you set the reference
value for arc voltage control when using peak current and background current. When
using continuous current only the p eak voltage parameter shall be entered.
GB
-- 1 3 --
dpa8d1ea
If no value is entered for peak voltage a value measured right after the welding start
is used as reference value.
If no value is entered for background voltage and pulsed welding current has been
selected, no arc voltage control takes place when background current is used.
NOTE! A time slope cannot be indicated in sector 1 for peak voltage and background
voltage.
In order to stabilise the arc b efore starting t he arc voltage control, a delay time can
be entered. During the delay t ime the AVC unit is locked.
If no delay time is entered the following applies:
S The d elay time will be equally long (at least 5 seconds) as the slope--up tim e (if
any) for the welding current.
If the slope--up time is shor ter than 5 seconds, the AVC unit can star t controlling
when the slope time has elapsed, but only by increasing the arc voltage (arc
length).
S If no slope--up time has been entered for the welding current, a fixed delay time
of 5 seconds applies. The AVC unit is not completely locked -- the arc voltage
(arc length) can be increased.
2.7 Weaving
Weaving is used if you want to oscillate the electrode laterally when welding with
welding tools fitted with a weaving unit.
In the Weaving parameter group four parameters are represented:
S WEAVE AMPLITUDE (5 mm)
S WEAVE SPEED (5 mm/s)
S DWELL TIME RIGHT (1 s)
S DWELL TIME LEFT (1 s)
amplitude (mm)
dwell time (s)
right
left
dwell time (s)
Weave speed (mm/s)
The values in brackets are preset values. If one of the parameter values is indicated
in the display, the preset values will come up automatically.
The weaving motion can be synchronised with the welding current (pulse current) so
that the pulse current sets in at the same time as the electrode is in dwell position.
This is also called special pulsing and is described in the section Special Pulsing
on page 10.
GB
-- 1 4 --
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. T he program then continues from the position in the welding
program where it was interrupted.
4 TO GET STARTED
4.1 General
Some of the factors controlling the welding process are specific to each one o f the
welding tools, for example the rotation speed. T herefore, every welding program
must be connected to a tool code, associated with the tool that the program was
made up for.
