The WELDINGER MEW 250SYN alu is a portable, single-phase (230V), air-cooled MIG/MAG/WIG/MMA welding inverter for DC welding. Preset synergic programs facilitate MIG/MAG welding of mild steel. All common metals can be welded in MIG/MAG mode. Rutile, stainless steel, steel and basic electrodes can be used for manual metal arc welding (MMA). To be able to work in LIFT TIG mode, you need a special TIG hosepack with external gas control
Its clearly laid out display allows welding parameters and auxiliary functions to be set quickly and makes it easy to switch between welding processes. The polarity is conveniently reversed on the front of the device for cored wire operation, and a spool gun interface is also available for even more flexibility when welding. For MIG welding of aluminum, a Teflon core and a wire guide roller are already included in the scope of delivery. A matching spool gun is available separately.
– Synergy mode for 0.6, 0.8 and 1.0 mm steel wire (gas-shielded arc welding only)
– Robust two-roll drive made of metal, holder for D100/D200 wire rolls
– Fine adjustments for burn-back control, induction, hot start and arc start
– Automatic adjustment of the other value for voltage and welding current setting
– High-quality hose package MB 250 with 3 m Euro central connection
– Aluminum welding
– 2- and 4-stroke operation
– Flux-cored wire welding
– Spoolgun interface
We recommend WELDINGER cored wire 0.8 mm/1 kg (9857), 0.8 mm/2 kg (article 4378), 0.8 mm/5 kg (4382).
MMA functions (electrode welding)
– Weldable electrode diameters 2-4 mm
– Hot Start and Arc Force adjustable
– Antistick and VRD can be switched on
Hot Start: prevents the electrode from sticking by briefly overlapping / increasing the welding current (adjustable from 0-10 A).
Arc Force: automatically regulates the current value to keep the arc constant for as long as possible.
Anti-stick: shortly before the short circuit, the system delivers the set maximum current to prevent the electrode from sticking and annealing.
VRD (Voltage Reduction Device): When the device is switched on but not ready for welding, the working voltage is automatically reduced to a safe level, which prevents injuries if the electrode is accidentally touched.
For electrode welding, we offer a suitable electrode holder cable as an accessory (article 2003).
– Lift TIG operation (DC)
A suitable WELDINGER SR 17 V TIG hosepack with external gas control and 13 mm mandrel (item 5604), as well as all accessories for MIG/MAG, TIG and electrode welding can be found in our store. As a practical MIG/MAG starter kit, we recommend the WELDINGER MAG-Set 2 wear part set (item 4192).
The WELDINGER MEW 250SYN alu is ideal for welders who want to weld aluminum or stainless steel as well as steel. Multifunctional welding processes offer maximum flexibility for different materials and locations. Whether you use the inverter primarily as a workshop device for work on vehicles or as a mobile device with cored wire/electrode: Thanks to the robust technology, useful auxiliary functions and its exemplary compact design, the MEW 250SYN alu delivers the best results with unsurpassed working comfort.
