Synergic welding – is a synergic welding machine worth buying?

Synergic welding is a function that MIG/MAG semi-automatic welding machines are equipped with. They make it  easier to fine tune all the important settings to your needs. So what exactly is synergic welding? Is a synergic welding machine right for you?

MIG/MAG welding - important parameters

MIG/MAG welding requires careful selection of specific settings. Their proper use affects the process and quality of the welded seam. These settings are:

    • Arc voltage - depends on the type of gas and arc length. The longer the arc, the more the voltage increases. The shorter the arc, the lower the voltage. When setting this, take into account the type of gas shield, the type and thickness of the welded material, and the electrode wire diameter and outlet. A welding arc that is too short causes slag to form on the weld seam, whereas one that’s too long causes splatter, porosity, and the weld seam to melt.
    • Wire feed speed - the second most important parameter after arc voltage. It should be set so that the melting of the wire is stable. Wrong speeds cause disruptions during the weld and unstable ignition of the arc. If the speed is too high, it “pushes” the handle and the characteristic dimming of the arc. If there is a break in the arc, the wire feed speed is probably too low.
  • Current voltage – this affects the shape and the depth of penetration, as well as the efficiency of the melting electrode wire. Low voltage produces an oval-shaped fusion. Setting a voltage too high produces a partial recess of fusion.
  • Wire type and diameter – the wire is selected according to the type of welded material. Its diameter is usually 0,6-1,6 mm and depends on the thickness of the element and the welding position.
  • Shield gas type and flow rate – shielding gas affects the arc, depth of fusion, amount of splatter, and quality of the weld seam. Low-alloy and unalloyed steels are welded in an active mixed gas shield. Inert gases are usually selected for metals susceptible to oxidation (magnesium, copper, aluminum, and their alloys). Flow rates must be adjusted so that the welding arc and pool are well protected. Low gas flow may cause  porosity in the weld seam. High gas flow may cause the so-called blowing of the arc.
    • Welding speed – it depends on the current intensity and arc voltage. In the MIG/MAG method, the welding speed is usually in the range of 25-130 cm/min.
    • The welding handle tilt angle – affects the depth of penetration, the width, and the shape of the weld seam. Tilting a welding handle in the direction of welding can create a deeper and narrower weld seam. Tilting in the opposite direction makes a shallow weld, and the bead of the weld seam is wider and higher.
  • The free outlet of the electrode wire – the distance between the end of the electrode wire and a current tip. The free outlet depends on the wire type and diameter, arc voltage, and current intensity. If it’s too short, the wire may stick and damage the tip. If the free outlet’s too long, the arc becomes unstable.

What is synergic welding?

In welding, synergy is a function in MIG/MAG welding machines that saves a great deal of time choosing work settings. Just pre-set for material, gas shield, wire diameter, and then arc power. The machine automatically adjusts wire speed, voltage, and other data.

Why choose synergy?

When welding, lots of factors need to be set to get the desired results, a strong and aesthetically pleasing weld seam. It wasn’t always easy to choose the settings on a welding machine before using it because of all the variables. The synergy function is really useful because when one setting is changed, the other ones automatically change, so your welding is smooth and error-free.

You could say that Synergy is actually a program that sets up your device to work in the right way. It doesn’t take much time, and you have peace of mind that all the settings have been correctly set. So Synergy is a great help for hobbyists as well as pros.

Synergy is also very useful in pulsed welding. This is because you need to choose extra current settings. These are:

  • inductance,
  • pulsation balance,
  • pulsation frequency,
  • the correction of the peak current voltage,
  • the correction of the base current voltage.

Synergic control, like the Pulse option, is available in professional welding equipment (you can find them in our store).

Synergic welding machines – are they worth it?

Some welders still haven’t switched to semi-automatic welding machines with synergic control even as they become more and more popular. The auto settings let you start work quickly and avoid problems later with settings which can result in mistakes, higher costs and lost time. You can always adjust certain parameters yourself to fine tune the welding process.

The way settings are adjusted by synergy largely depends on the machine. In the Sherman MIG 200 HD semi-automatic welding machine, which is recommended for beginners, the wire feed is automatically set according to the voltage. In a slightly more advanced device, such as the Magnum 210 Synergia, the parameters are set according to the wire diameter. Fully synergic welding machines, such as the Magnum 208 ALU Synergia,  adjust the settings according to the wire diameter, material type, and thickness.

Synergic welding machines are a great choice for both do-it-yourself enthusiasts, as well as professionals. The easy-to-use welding settings take out the guesswork during set-up, dusring operation and give you peace of mind so you can focus on welding.
