Why Choose the Fronius TransSteel 2200C?

The TransSteel 2200C is one of the most advanced compact synergic MIG welders available.

It offers:

Synergic control
Digital parameter adjustment
Extremely stable arc
Steel, stainless and aluminium programmes
Excellent thin sheet performance
Professional build quality
Pulse-like arc characteristics (depending on programme)

Equipment You’ll Need

Fronius TransSteel 2200C
ER70S-6 Mild Steel Wire
Argon / CO₂ shielding gas
Correct drive rollers
Correct contact tip
Earth clamp
Gas regulator

Step 1 – Install the Wire

For most fabrication work choose:

0.8 mm ER70S-6

Suitable for:

1 mm
2 mm
3 mm
5 mm
6 mm steel

Step 2 – Select the Correct Drive Rollers

Use:

0.6 mm
0.8 mm
1.0 mm
1.2 mm

Set roller pressure so the wire feeds smoothly without crushing.

Step 3 – Connect the Shielding Gas

For mild steel:

90% Argon / 10% CO₂

92% Argon / 8% CO₂

Recommended flow:

10–14 L/min

Step 4 – Check Polarity

Earth (−)

Flux Cored

Step 5 – Enable Synergic Plate Thickness Mode

One of the best features of the Fronius TransSteel 2200C is its Synergic Plate Thickness Mode, which automatically selects the correct wire feed speed and voltage based on the thickness of the steel you’re welding.

If you’ve never used a TransSteel before, here’s how to activate it.

1. Press the Silver Arrow Button

Locate the silver arrow button on the top left-hand side of the control panel.

Press this button until the plate thickness icon is illuminated.

The correct icon is the one showing two arrows with a horizontal line between them.

This indicates the machine is now operating in Plate Thickness Mode rather than manual parameter adjustment.

2. Select the Material Thickness

Once Plate Thickness Mode is active, simply rotate the main control knob.

As you turn the knob, the digital display will change to show the material thickness (in millimetres).

For example:

1.0 mm
2.0 mm
3.0 mm
5.0 mm
6.0 mm

Select the thickness that most closely matches your workpiece.

3. Let the Machine Do the Work

Once you’ve selected:

Material
Wire Diameter
Shielding Gas
Plate Thickness

…the TransSteel 2200C automatically calculates:

Wire Feed Speed
Welding Voltage
Current Output
Arc Characteristics

This is what makes the Fronius Synergic system so effective—it removes much of the guesswork while still allowing experienced welders to fine-tune the arc.

4. Fine-Tune if Required

The automatically selected settings are an excellent starting point.

If required, you can then use:

Arc Length Correction to make the arc softer or crisper.
Dynamic Correction to adjust penetration and arc force.

For most mild steel fabrication, many welders find that the default synergic settings require very little adjustment.

Gas Flow

Indoor:

10–14 L/min

Outside:

Increase slightly if required, but remember excessive gas flow can cause turbulence.

Contact Tip to Work Distance

0.8 mm wire:

10–12 mm

1.0 mm wire:

12–15 mm

Common Problems

Too Much Spatter

Increase Arc Length slightly.
Check gas flow.
Clean the material.

Poor Penetration

Increase Dynamic.
Increase voltage slightly.
Slow your travel speed.

Wire Stubbing

Increase wire speed slightly or reduce voltage trim.

Burn Through

Reduce voltage and increase travel speed.

Pro Tips

Always use quality shielding gas.
Keep the torch liner clean.
Replace worn contact tips.
Use Fronius synergic programmes whenever possible.
Fine tune with Arc Length and Dynamic rather than switching to manual settings.

My Recommended Everyday Setup

If I were preparing a customer’s TransSteel 2200C for general workshop use:

0.8 mm Böhler or equivalent ER70S-6 wire
90/10 Argon/CO₂
Steel Synergic programme
0.8 mm wire selected
Arc Length = 0
Dynamic = 0
Gas = 12 L/min

That setup covers the vast majority of mild steel fabrication from around 1–6 mm with only small adjustments.

WeldAssist Pro Tip

Always use Plate Thickness Mode when learning the TransSteel 2200C.

Instead of manually adjusting voltage and wire feed speed independently, simply enter the material thickness and let the Fronius Synergic system calculate the optimum settings. This produces excellent results straight away and makes setup significantly quicker and more consistent, particularly when moving between different material thicknesses.
