1.4 Keys

You can use the arrow keys to move the cursor to different lines in the display.

The menu key will always return you to the main menu.

The plus/minus keys are used to increase (+) or decrease (−) the value of a

setting.

The two plus/minus keys are each marked with their own symbol. Most settings can

be defined using either the plus or minus key, but certain settings must be defined

using a key marked or (the symbols appear in the display).

Pressing a key briefly produces an increase/decrease in small steps. If you hold a

key down for longer, the size of the steps increases.

Soft keys

The five keys in a row under the display have a

variety of functions. These are the ”soft keys”, i.e.

they can have different functions depending on

which menu you are using. The current functions

of these keys are shown by the text in the bottom

3 MIG/MAG WELDING

Main menu −−> Process

The arc in MIG/MAG welding melts a filler wire (the electrode) that is continuously

fed into the weld, with the molten zone being protected by a shielding gas.

Pulsing is used to affect the transfer of the droplets from the arc so that it is stable

and does not produce spray, even with low weld data.

The table on page 60 shows the wire diameters that can be selected for MIG/MAG

welding with DIP/SPRAY.

3.2 Function explanations for settings

3.2.1 Voltage

Higher voltage increases the arc length and produces a hotter, wider weld pool.

The voltage setting differs between synergy and non synergy modes. In synergy

mode the voltage is set as a positive or negative offset from the synergic line of the

voltage. In non synergy mode the voltage value is set as an absolute value.

The voltage is set in either the measure image−, the weld data setting menu, or the

fast mode menu. When the remote control unit is used the setting can be made from

this.

3.2.2 Wire feed speed

This sets the required feed speed of the filler wire in m/minute.

The wire feed speed is set in either the measure image, the weld data setting menu,

or the fast mode menu. When the remote control unit is used the setting can be

made from this.

3.2.3 Inductance

Higher inductance results in a wider weld pool and less spatter. Lower inductance

produces a harsher sound but a stable, concentrated arc.

Only applies for MIG/MAG welding with dip/spray.

3.2.4 Regulator type

Affects the short circuit process and heat in the weld.

This setting should not be changed.

3.2.5 Pulse current

The higher of the two current values in the event of pulsed current.

Only applies for MIG/MAG welding with pulse.

3.2.6 Pulse time

The time the pulse current is on during a pulse period.

Only applies for MIG/MAG welding with pulse.

3.2.7 Pulse frequency

Time for background current, which, along with the time for pulse current, gives the

pulse period.

Only applies for MIG/MAG welding with pulse.

GB

− 17 −

Only applies for MIG/MAG welding with pulse.

Time

3.2.9 Slope

Slope means that the pulse current rises/falls slowly to the set value. The slope

parameter can be set in nine steps, with each step corresponding to 100 µs.

Slope is significant with respect to sound. A steep slope generates a higher, sharper

sound. A slope that is too gentle can in the worst case, affect the pulse’s capacity to

cut off the droplet.

Only applies for MIG/MAG welding with pulse.

3.2.10 Ka

Ka is the proportional element and corresponds to the regulator’s amplification. A

low value means that the voltage is not maintained at a constant level as precisely.

Only applies for MIG/MAG welding with pulse.

3.2.11 Ki

Ki is the integrating element that attempts in the longer term to eliminate an error.

Here too, a low value will produce a weaker regulatory effect.

Only applies for MIG/MAG welding with pulse.

3.2.12 Synergy

Each combination of wire type, wire diameter and gas mixture requires a unique

relationship between wire feed speed and voltage (arc length) to obtain a stable

functioning arc. The voltage (arc length) automatically conforms in accordance with

the pre−programmed synergic line you have selected, which makes it much easier to

find the correct welding parameters. The relationship between the wire feed speed

and the other parameters is called the synergic line.

It is also possible to order other packages of synergy lines, but these must be

installed by an authorised ESAB service engineer.

3.2.13 Gas pre−flow

Gas pre−flow controls the time during which shielding gas flows before the arc is

struck.

GB

− 18 −

bi09d1e2

3.2.14 Creep start

Creep starting feeds out the wire at 50% of the set speed until it makes electrical

contact with the workpiece. With a hot start it is 50% of the hot start time.

3.2.15 Hot Start

Hot start increases the wire feed speed and voltage for an adjustable time at the

start of welding, thus reducing the risk of poor fusion at the beginning of the joint.

Hot start wire speed

It is possible to increase the wire feed speed during a specific period compared to

the present wire feed speed to provide more energy during the weld start and ensure

penetration. The speed is set relative to the ordinary wire feed speed. The time

starts when the arc is ignited and the length is the set hot start time. Synergy gives

an increase in the wire speed by 2 m/min.

Hot start voltage

The voltage increases by 2 volts in addition to the contribution from the synergy line

slope and the extra 2 m/min in wire feed speed. In non synergy mode, the voltage in

question will be the one set and it is not synergy dependent.

Note!: It is possible to set negative values for the hot start wire feed and hot start

voltage. This can be used with high weld data to give a smooth weld start by initially

”stepping up” the weld data.

− Hot start is enabled in the measure image and the settings are defined in the

settings menu.

3.2.16 Crater filling

Crater filling makes a controlled reduction in the heat and size of the weld pool

possible when completing the weld. This makes it easier to avoid pores, thermal

cracking and crater formation in the weld joint.

In pulse welding mode it is possible to choose between pulsed and non pulsed crater

filling. Non pulsed crater filling is faster to do. Pulsed crater filling takes a little longer,

yet gives spatter free crater filling when appropriate values are used.

Synergy

In synergy mode the crater filling time and the final wire feed speed are both set in

pulsed and non pulsed crater filling. The voltage and the pulse parameters drop to

the final values with the help of synergy.

Non synergy

In non synergy mode the settings can be changed to give another arc length at the

end of crater filling.

The final voltage can be set for non pulsed crater filling. The final voltage, final pulse

current, final background current and the final frequency can be set for pulsed crater

filling.

The final parameter values must always be equal to or lower than the set values for

continuous welding. If the settings for continuous welding are lowered below the set

final values they will also lower the final values. The final parameter values will not

increase again if the setting for continuous welding is increased.

GB

− 19 −

bi09d1e2

Example:

You have 4 m/min as the final wire feed speed and lower the wire feed speed to

3.5 m/min. The final wire feed speed will also be lowered to 3.5 m/min. The final wire

speed remains at 3.5 m/min even when the wire feed speed is increased again.

− Crater filling is enabled in the measure image and the settings are defined in the

settings menu.

3.2.17 Pinch−off pulse

Pinch−off pulse is a pulse that is added to ensure than no ball is formed on the wire

when welding stops.

Only applies for MIG/MAG welding with dip/spray. When pulsing completion is

synchronised with a pulse, finishing pulse.

3.2.18 Burnback time

Burnback time is a delay between the time when the wire starts to brake until the

time when the power source switches off the welding voltage. Too short a burnback

time results in a long wire stickout after completion of welding, with a risk of the wire

being caught in the solidifying weld pool. A long burnback time results in a shorter

stickout, with increased risk of the arc striking back to the contact tip.

3.2.19 Gas post−flow

Gas post−flow controls the time during which shielding gas flows after the arc is

extinguished.

3.2.20 Limits

In this function you can choose a limit number. For settings, see chapter 16

”Configuring limits”.

3.2.21 Spot welding

Select Spot welding when you want to ”spot−weld” thin metal sheets.

Note! You can not shorten the weld time by releasing the gun trigger.

arc melts the electrode, and its coating forms a protective slag.

The table on page 61 shows the electrode diameters that can be selected for MMA

welding.

4.2 Function explanations for settings

4.2.1 Current

A higher current produces a wider weld pool, with better penetration into the

workpiece.

Current is set in either the measure image, the weld data setting menu, or the fast

mode menu.

4.2.2 Arc force

The arc force controls how the current changes when the arc length changes. A

lower value gives a calmer arc with less spatter.

4.2.3 Min. current factor

The min. current factor setting is used in conjunction with certain specific electrodes.

Note! This setting should not be changed.

4.2.4 Synergy

Synergy for MMA welding means that the welding power source automatically

optimises the properties of the electrode type and diameter selected.

4.2.5 Limits

In limits you can choose a limit number. For settings, see chapter 16 ”Configuring

limits”.

− Limits are enabled in the weld data setting menu.
