MIG/MAG standard synergic

MIG/MAG standard synergic welding is a MIG/MAG welding process covering the entire power range of the power source with the following arc types:

Dip transfer arc
Droplet transfer occurs in the lower power range during the short circuit.

Intermediate arc
The droplet increases in size at the end of the wire electrode and is transferred in the mid power range during the short circuit.

Spray arc
A short circuit-free transfer of material in the high power range.

1. General information
2. Welding processes, procedures, and welding characteristics for MIG/MAG welding

MIG/MAG pulsed synergic

MIG/MAG pulsed synergic welding is a pulsed arc process with a controlled material transfer.
In the base current phase, the energy input is reduced to such an extent that the arc barely burns steadily and the surface of the workpiece is preheated. In the pulsing current phase, an accurately timed current pulse guarantees a precise detachment of the weld material droplet.
This principle guarantees low-spatter welding and precise operation throughout the entire power range.

IMPORTANT! To facilitate exact positioning of the wire electrode, the following procedure is possible when the "Wire threading" button is pressed and held down.

• Hold the button for up to one second ... the wire speed stays at 1 m/min or 39.37 ipm for the first second.
• Hold the button for up to 2.5 seconds ... after one second, the wire speed increases evenly within the next 1.5 seconds.
• Hold the button for more than 2.5 seconds ... after 2.5 seconds, the wire is fed at a constant rate equal to the wire speed set for the Fdi welding parameter.

If you release the "Wire threading" button and press it again before one second has elapsed, the sequence starts again from the beginning. This makes it possible to continuously position the wire at a low wire speed of 1 m/min or 39.37 ipm where necessary.

If there is no wire threading button present, the torch trigger can be used in a similar way. Before using the torch trigger for wire threading, proceed as follows:

IMPORTANT! If the torch trigger is pressed instead of the "Wire threading" button, the welding wire runs at the feeder creep speed (depending on the welding program) for the first 3 seconds. After these 3 seconds, wirefeeding is briefly interrupted.

The welding system detects that the welding process should not start, but that the wire is to be threaded in. At the same time, the gas solenoid valve closes, and the welding voltage on the wire electrode is switched off.

If the torch trigger is kept pressed, wirefeeding restarts immediately without shielding gas and welding voltage, and the process continues as described above.

SynchroPulse is recommended for welded joints with aluminum alloys whose weld seams should have a rippled appearance. This effect is achieved using a welding power that changes between two operating points.

The two operating points result from a positive and negative change in the welding power to a dFd (delta wire feed) value that can be adjusted in the Setup menu (delta wire feed: 0.0 - 3.0 m/min or 0.0 - 118.1 ipm).

• Frequency F of the operating point change (set in the Setup menu)
• Arc length correction for the lower operating point (set via the arc length correction parameter on the control panel)
• Arc length correction for the higher operating point (set in the Setup menu, parameter Al.2)

To enable SynchroPulse, you must change at least the value of the F (Frequency) parameter from OFF to a variable in the range of 0.5 to 5 Hz in the process Setup menu.

• A low base current I-G rises steeply to the significantly higher pulse current I-P and drops back to the base current I-G after the Duty cycle dcY time.
• This results in an average current that is lower than the set pulse current I-P.
• During pulse welding, small sections of the welding location melt quickly and then rapidly re-solidify.

The power source controls the "Duty cycle dcY" and "Base current I-G" parameters according to the set pulse current (welding current) and pulse frequency.

As the arc becomes shorter, the welding voltage may also fall so that the rod electrode is more likely to stick to the workpiece. This may also cause the rod electrode to burn out.

Electrode burn-out is prevented by activating the anti-stick function. If the rod electrode begins to stick, the power source immediately switches the welding current off. The welding process can be resumed without problems once the rod electrode has been detached from the workpiece.

The anti-stick (Ast) function can be activated and deactivated in the Setup menu for the setup parameters for MMA welding.

Measuring the welding circuit resistance makes it possible to have a constant welding result at all times, even with hosepacks of different lengths. The welding voltage at the arc is then always precisely regulated, regardless of the length and cross-sectional area of the hosepack. The use of arc length correction is no longer required.

The calculated welding circuit resistance is shown on the display.

r = welding circuit resistance in milliohm (mOhm)

If the welding circuit resistance has been measured correctly, the set welding voltage will correspond exactly to the welding voltage at the arc. If you manually measure the voltage on the output jacks of the power source, this voltage will be higher than the welding voltage at the arc - that is, higher by the same amount as the voltage drop of the hosepack.

• If the length or cross-sectional area of the hosepack has changed, measure the welding circuit resistance again
• Measure the welding circuit resistance for every welding process separately with the appropriate welding power-leads
