What Dabu publishes for the MIG350

The All-in-one MIG350 puts the power source and wire feeder in one cabinet. It takes three-phase AC 380 V at 50/60 Hz. On MIG it draws a maximum of 22 A and an effective 17 A; on MMA the figures are 24 A and 18 A. Output runs from 40 to 350 A on MIG and from 20 to 350 A on MMA. Dabu rates it at 350 A on a 60% duty cycle and 271 A at 100%.

The wire table is what sets this model apart. It names Fe wire from 0.8 to 1.0 mm, stainless steel from 1.0 to 1.2 mm, and Al-Si and Al-Mg aluminium wire from 1.0 to 1.2 mm. Stick electrodes of 1.6, 2.0, 2.5 and 3.2 mm are listed. Dabu describes dual-pulse inverter control and credits it with lower spatter and a better aluminium bead. The cabinet is rated IP21S and measures 85 × 45 × 78 cm overall.

Building an aluminium package

Buying guidance

Many machines say they weld "multiple materials". The MIG350 table goes further and names Al-Si and Al-Mg wire sizes, which gives an aluminium enquiry a solid starting point. You still need the parts that make soft wire feed reliably. Tell Dabu the base alloy, the filler grade and the wire diameter you plan to use.

Then ask which drive rolls, liner and contact tips come with the machine, and whether the torch supplied is approved for aluminium wire at the length you need. If the quote is for steel parts with aluminium as an option, ask for the aluminium kit as its own priced line. Any sample weld should be made with the same torch and feed path you will receive.

Putting the dual-pulse claim to work

Buying guidance

Dabu says its dual-pulse control cuts spatter and improves the look of aluminium welds. How much that helps on your parts depends on the alloy, the joint preparation, the wire, the gas and the settings the operator uses. Treat it as a feature to test on your own job.

Ask which programs and adjustments the machine offers for the wire you quoted. Request a demonstration that records the settings, shows the start and finish of each weld, and notes any grinding or rework. If appearance is what you are buying for, describe the finish you need before the test. If the welds carry load, agree the inspection rules first. A nice bead photo is a start; a recorded trial on your joint is the deciding step.

350 A versus 271 A in daily use

Buying guidance

The headline 350 A applies at a 60% duty cycle. For work with no breaks, Dabu's figure is 271 A. The page gives no ambient temperature or cycle time for either figure, so ask Dabu for the full duty chart of this model with its test conditions before setting it beside another machine.

Think about your real pattern. Long continuous seams near the top of the range need a different machine choice than short welds broken up by fit-up and turning the part. Ask for the ratings of the torch, its cooling and the earth lead too, because a lighter torch limits the whole station. For a production cell, give Dabu both your peak current and your repeated arc-on pattern.

Living with a built-in feeder

Buying guidance

With the feeder inside the cabinet, the torch length sets how far the operator can reach from the machine. Check how easily the reel compartment opens and where the cabinet will stand. The overall size of 85 × 45 × 78 cm needs space around it for loading wire, routing leads and reaching the controls.

For large workpieces, send Dabu a layout sketch and the reach you need, and ask whether a longer torch or another feeding set-up is approved. If you need a separate feeder that travels to the work, look at Dabu's split-feeder model instead. The page gives no weight, wheel kit or lifting points for the MIG350. If the machine will move between bays, ask for those details.

Preparing the 380 V supply

Buying guidance

Pass the published input data to whoever installs the machine: 380 V three-phase, 50/60 Hz, with MIG drawing up to 22 A and MMA up to 24 A. Add the full manual and your own site supply details. Ask Dabu for the installation requirements of the revision you are buying, covering protection, earthing and cable sizing.

The circuit is designed from those input figures and the site conditions. The output current on the front panel plays no part in that calculation.

Comparing quotes on the same package

Buying guidance

The MIG350 is listed for iron, stainless and aluminium wire, yet a quote may only cover one of them. Ask each supplier to list the torch, regulator, gas hose, feed parts, cables and stick accessories. Ask what has to change when you switch from steel to aluminium wire and whether those parts are in the price. Request the manual and spare-part numbers for the configuration quoted.

When you test machines side by side, use the same workpiece, filler and inspection rules for each. Note set-up changes, spool access, reach and the duty demand next to the weld result. Quantity and lead-time lines on a product page date quickly. Ask for a dated quotation stating price validity, contents, support and delivery terms.

What to pin down with Dabu

Buying guidance

Have Dabu state in writing the temperature and cycle time behind the 350 A and 271 A ratings, the torch and earth lead ratings, and the exact aluminium feeding parts for your Al-Si or Al-Mg wire. Have the dual-pulse programs for your wire named in the offer.

Request the installation requirements, the weight and handling details, and a bill of supply listing every included part. Agree in advance how the recorded sample will be inspected and what result counts as a pass.

A useful brief for the supplier

Fill in each item. Ask the supplier to respond against the same specification so two offers can be compared.

1. Base alloy, filler grade, plate thickness and joint shape.
2. Wire diameter, reel format, shielding gas and the reach you need.
3. Your three-phase supply and the distance from the panel.
4. Peak current and how long each weld runs; ask for the full duty chart.
5. Torch cooling, feed parts and a line-by-line bill of supply.
6. A recorded sample weld, the inspection rules and a dated quotation.
