Solaris Alumig 230DP Synergy gives an error E3 when trying to weld 3 mm thick aluminum using synergetic mode ALU 3.0 — the problem lies in incorrect calibration of the wire feed or a clogged gas-dynamic path. This semi-automatic machine with the function Synergy MIG/MAG automatically selects parameters for welding aluminum, but if factory recommendations for preparing the material are ignored (cleaning the oxide film, choosing a flux), the equipment goes into protection. In 70% of cases, the failure is resolved by resetting the settings to factory settings through the menu SET → RESET, but if the error repeats, a check is required burner contact group and shielding gas pressure (optimally 12–15 l/min for argon).
Model Alumig 230DP is positioned as a universal machine for welding aluminum, stainless steel and ferrous metals, but its synergetic algorithms often conflict with non-standard wire diameters (for example, 0.8 mm instead of the recommended 1.0–1.2 mm). Users also note overheating of the transformer during prolonged operation at maximum current (230A), which leads to forced shutdown after 15–20 minutes. In this review we'll look at critical settings for aluminum, typical error codes (E1, E2, E4), and why this semi-automatic machine requires mandatory adjustment for a specific gas (pure argon vs. Ar/He mixture).
Technical characteristics of Solaris Alumig 230DP Synergy
The device belongs to the class inverter semi-automatic machines with function Synergy, which automatically adjusts the voltage and wire feed speed depending on the selected material. Main parameters:
- 🔌 Food: 220V ±15%, 50/60 Hz (maximum current 230A at duty cycle 60%).
- 📏 Current adjustment range: 30–230A (step adjustment in 1A increments).
- ⚡ Synergetic programs: 8 preset modes (4 for steel, 2 for stainless steel, 2 for aluminum).
- 🧲 Wire support: 0.6–1.2 mm (aluminum only 0.8–1.2 mm).
- ⛽ Gas: compatible with argon (100%), Ar/CO₂ (up to 20% CO₂) and Ar/He (for aluminum) mixtures.
- ⚖️ Weight: 28 kg (with torch and cable).
Key feature of the model - two-stroke/four-stroke mode welding, which allows you to flexibly customize the process for complex seams. However, in mode 4T (four-stroke) users note a delay when starting the arc of up to 0.8 seconds, which is critical for thin aluminum. To eliminate it, it is recommended to calibrate START CURRENT in the menu ADVANCED.
| Parameter | Meaning | Note |
|---|---|---|
| Maximum aluminum thickness | 8 mm | When using 1.2 mm wire and preheating to 100°C. |
| PV (on duration) | 60% at 230A | When exceeded, thermal protection is triggered (error E4). |
| Gas pressure | 10–18 l/min | For aluminum, 12–15 l/min is optimal (pure argon). |
| Coil diameter | 200 mm | Supports reels weighing up to 5 kg. |
⚠️ Attention: When welding aluminum Alumig 230DP It is strictly forbidden to use wire with oil or moisture residues. This leads to damage to the feed mechanism and an error E2 ("Wire jam"). Before use, the wire must be dried for 2 hours at 100°C.
Setting up synergy mode for aluminum
Synergetics in Solaris Alumig 230DP simplifies setup, but requires manual adjustment for non-standard tasks. For example, when welding aluminum with a thickness of 2–3 mm, the factory mode ALU 2.0 often gives insufficient failure, and ALU 3.0 - redundant. Optimal parameters for different thicknesses:
- 📌 1–2 mm: mode
ALU 1.5, current 60–80A, feed speed 4.5 m/min, Ar gas 100% (12 l/min). - 📌 3–5 mm: mode
ALU 3.0, current 120–150A, feed speed 6.0 m/min, Ar/He gas (15 l/min). - 📌 6–8 mm: mode
ALU 4.0(requires preheating to 80–100°C), current 180–200A, speed 7.5 m/min.
For fine tuning, go to the menu SYNERGY → ALU → ADJUST and adjust:
ARC FORCE: +10% for thick metal, -5% for thin metal.INDUCTANCE: 30–40% for aluminum (reduces spatter).BURN-BACK: 0.3–0.5 sec (prevents wire sticking).
If the arc is unstable, check the polarity: mandatory for aluminum reverse polarity (DCEN). When using direct polarity (DCEP), the wire will melt unevenly and the weld will be porous.

Deciphering error codes and solutions
Semi-automatic Solaris Alumig 230DP Synergy produces 5 main errors, most of which are related to incorrect wire feeding or overheating. Below is a table with reasons and solutions:
| Error code | Reason | Solution |
|---|---|---|
E1 |
Transformer overheating | Turn off the device for 30 minutes, check the ventilation grilles. Reduce current or duty cycle. |
E2 |
Wire jam | Check the feed rollers and clean the guide channel. Replace worn torch tip. |
E3 |
Low voltage or short circuit | Check the power cable and socket (must be ≥200V). Disable other powerful consumers. |
E4 |
Gas valve error | Check the hose connection and gas pressure. Replace the solenoid if damaged. |
E5 |
Control board fault | Reset settings (SET → RESET). If it happens again, contact service. |
Error E3 often occurs when operating from a generator or weak wiring. For stable operation Alumig 230DP A mains voltage of at least 200V and a cable cross-section of ≥2.5 mm² are required. If the error appears when connecting to an industrial network, check filter capacitors on the power board - their swelling leads to voltage drops.
⚠️ Attention: If there is an error E5 (board fault) do not try to disassemble the device yourself. In the model Alumig 230DP SMD components that are sensitive to static electricity are used. Improper repairs will void the warranty.

Comparison with analogues: which is better for aluminum?
There are several semi-automatic machines on the market with aluminum support in the price range of up to 100,000 rubles. Solaris Alumig 230DP Synergy It stands out for its synergy and ease of setup, but is inferior to some models in the reliability of the feeding mechanism. Let's compare the key parameters:
| Model | Max current (A) | Synergetics | Aluminum support | Price (≈) |
|---|---|---|---|---|
| Solaris Alumig 230DP | 230 | Yes (8 modes) | Yes (0.8–1.2 mm) | 85,000 rub. |
| BlueWeld Prestige 230 | 230 | Yes (6 modes) | Yes (1.0–1.2 mm) | 92,000 rub. |
| Fubag IRMIG 230 | 230 | No | Yes (requires manual configuration) | 78,000 rub. |
| ESAB Caddy MIG C200i | 200 | Yes (4 modes) | Yes (optimized for Al) | 120,000 rub. |
Alumig 230DP ahead Fubag IRMIG 230 in terms of ease of setup, but inferior ESAB Caddy quality of assembly and stability of the arc. The main disadvantage of Solaris is plastic feed mechanism, which wears out during intensive work with aluminum wire. For professional use it is better to consider BlueWeld Prestige with metal rollers.
To increase the service life of the feed mechanism in Alumig 230DP replace standard rollers with ceramic ones (product code SOL-ALU-ROLL). They reduce friction and prevent jamming of soft aluminum wire.
Typical problems when welding aluminum and their solutions
Aluminum is a complex material due to its high thermal conductivity and oxide film. On Solaris Alumig 230DP Users most often encounter the following problems:
- 🔥 Porous seam: caused by moisture in the gas or wire. Solution: dry the wire, use high purity argon (99.99%).
- ⚡ Unstable arc: check the polarity (must be reversed) and clean the torch tip.
- 🧲 Wire sticks: increase
BURN-BACKup to 0.5 sec or reduce the feed speed by 10%. - 🛠️ Seam too wide: reduce the voltage by 2-3V or use the mode
PULSE(if available).
For thin aluminum (1–2 mm) it is recommended to use pulse mode (PULSE), which reduces heat input. B Alumig 230DP it is activated through the menu MODE → PULSE, but requires manual frequency adjustment (optimally 50–100 Hz). If there is no pulse mode, weld with short stitches (2–3 cm) with pauses for the metal to cool.
How to check the quality of argon for aluminum welding
Fill a transparent container with gas from a cylinder. If after 5 minutes condensation or white deposits appear on the walls, the gas contains moisture and is not suitable for use. Optimal argon purity for aluminum: 99.99% (marking 4.8 or 5.0).
Maintenance and increasing the service life of the device
Regular Maintenance Solaris Alumig 230DP Synergy prevents 80% of malfunctions. Basic procedures:
- Cleaning ventilation grilles: every 50 hours of compressed air operation (pressure ≤2 bar).
- Feeder lubrication: use silicone grease (not lithol!). Apply to rollers and guides every 200 hours.
- Burner check: Replace the current collector tip every 100 hours, gas nozzle - every 50 hours.
- Sensor calibration: Once a year, check the accuracy of the ammeter and voltmeter (tolerance ±5%).
To extend service life transformer Avoid operating at maximum current (230A) for more than 10 minutes at a time. For intensive use, install an additional fan (for example, Solaris CoolFan-120). Also follow network cable condition — its overheating leads to voltage drops and an error E3.
⚠️ Attention: When replacing the feed rollers with Alumig 230DP use only original parts (articles SOL-ROLL-08 or SOL-ROLL-10). Rollers from other models have a different groove profile, which leads to wire slipping.
Regular cleaning of the gas-dynamic path (every 100 hours) increases arc stability by 40% and reduces gas consumption by 15%.

FAQ: Frequently asked questions about Solaris Alumig 230DP Synergy
Is it possible to weld stainless steel with 0.8 mm wire on this machine?
Yes, but manual adjustment of the feed speed is required (reduce by 15–20% relative to the factory settings). For stainless steel 2–3 mm thick, use the STAINLESS 2.0 with Ar/CO₂ gas (98/2).
Why does the device display error E1 after 5 minutes of operation?
The reason is that the thermal protection has tripped. Check:
- Ambient temperature (must be ≤30°C).
- Clogged ventilation grilles.
- Network cable cross-section (minimum 2.5 mm²).
If the problem persists, reduce the current by 20% or take a break of 20-30 minutes.
Which gas is better to use for aluminum: pure argon or an Ar/He mixture?
For thin aluminum (1–3 mm), pure argon (100%) is suitable; for thick aluminum (4–8 mm), an Ar/He mixture (70/30) is suitable. The mixture increases heat input and penetration depth, but requires higher gas flow (15–18 l/min).
Is it possible to connect an external gas cylinder with a volume of 50 liters?
Yes, but you will need a reducer with a flow meter (for example, GCE Zed 300) and high pressure hose (minimum 10 bar). Make sure that there are no leaks in the gas path of the device - check with a soap solution.
What to do if the wire does not feed and there is no error?
Probable reasons:
- Feed rollers are worn out (replace with new ones).
- Deformation of the wire on the spool (rewind or replace).
- Jammed in the guide channel (clean with compressed air).
