Synergic welding inverter WELDINGER MEW 238 SYN puls pro

Digital professional welding inverter for MIG/MAG, TIG and MMA welding

Synergy functions for steel, stainless steel and aluminum, LCD display for parameter control

The WELDINGER MEW 238 SYN puls pro professional is a portable, single-phase (230V), air-cooled MIG/MAG/WIG/MMA welding inverter for DC welding. Its particularly user-friendly graphic display provides all relevant information about set values such as voltage, welding current, wire speed and selected special functions at a glance.

In addition, the intuitively designed menu navigation allows quick switching between welding processes and rapid setting of all desired parameters. It is controlled digitally via two push buttons. Preset synergy curves facilitate the processing of 0.8 and 1.0 mm steel and stainless steel (308, 316), as well as 1.0 and 1.2 mm aluminum. The device can also be used in purely manual MIG/MAG mode.

Additional MIG/MAG functions include two- and four-stroke, pulse, double pulse, spot and continuous spot welding. For fine adjustment, the burn-back, inductance, soft start, gas pre-run and gas post-run can be set.

The device is also equipped with a quick welding function to meet special requirements. You can select high-speed welding in normal mode or with pulse and double pulse, speed-up high-speed welding, root welding or root welding with pulse.

To switch to cored wire mode, simply change the polarity on the front of the appliance; inside, the appliance can be switched from standard to spool gun mode. A matching spool gun with 12-pin control socket is available separately (item 3148). A 1.0/1.2 mm wire reel and a Teflon core are included for aluminum welding. 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). TIG welding is possible in DC-Lift TIG mode via the Euro central connection, suitable welding torches for TIG and MMA are available as accessories in our store.

MIG/MAG functions
– Synergy operation for: 0.8, 1.0 mm steel and stainless steel wire, as well as 1.0 and 1.2 mm aluminum
– Robust metal wire feed motor, holder for D200 wire reels
– Fine adjustments for backfire control, induction, soft start and post-flow time
– High-quality hose package MB 24 with Euro central connection
– Suitable for aluminum and stainless steel welding
– 2- and 4-cycle operation, pulse, double pulse, spot, continuous spot welding
– Suitable for cored wire with convenient polarity reversal on the front of the device
– Spool gun interface 12-pin

MMA functions (electrode welding)
– Weldable electrode diameter 1.5-4 mm
– Hot Start, Arc Force (adjustable) and Antistick

Hot Start: prevents the electrode from sticking by briefly superimposing / increasing the welding current 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 welding machine is switched on but not ready for welding, the output voltage is reduced to a user-safe level. Even if you come into contact with the electrode, work safety is guaranteed thanks to VRD.

In TIG mode, the welding current is adjustable and the shielding gas is regulated externally via the separately available hose package.

In our store you will find a large selection of WELDINGER accessories, wear parts and consumables for all welding processes at an excellent price/performance ratio. The WELDINGER MEW 238 SYN dig professional offers maximum flexibility for different materials and locations.

Whether you use the inverter primarily in maintenance, for installations or in the automotive sector: Thanks to its compact and very robust design in combination with state-of-the-art inverter technology and a user-friendly user interface, the MEW 238 SYN puls professional delivers excellent results in every welding process.
