Professional welding inverter WELDINGER MEW 300 SYN dig puls pro (400 V)

With digital control, pulse and double pulse

Synergic standard programs for mild steel, V2A, CuSi soldering, aluminum and cored wire

The WELDINGER MEW 300 SYN dig puls pro is a portable, three-phase (400V), air-cooled MIG/MAG/WIG/MMA welding inverter for DC welding. Its ultra-modern menu navigation provides a perfect overview of set values such as voltage, welding current and wire speed as well as selected special functions for every welding process. It is controlled digitally via two push buttons and two push buttons.

Preset synergy curves facilitate the processing of suitable material. The LCD display allows welding parameters and auxiliary functions to be set quickly, as well as an uncomplicated, quick change between welding processes. The polarity is conveniently reversed on the front of the device for cored wire operation, and the device can be switched from normal to spool gun operation via the menu navigation. A matching spool gun with 2-pin connection is available separately.

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) (electrode holder cable with 13 mm mandrel is available as an accessory). To be able to work in DC LIFT TIG mode, you need a separately available TIG hosepack with external gas control and 13 mm mandrel (item 5604).

The inverter has been technically optimized and now also comes with an extended supply cable (4 m), pulse, double pulse and synergic CuSi function.

MIG/MAG functions
– Synergy mode for 0.8, 1.0 or 1.2 mm steel wire, V2A, aluminum welding wire, MIG brazing wire or cored wire
– Robust four-roller drive made of metal, can be used for D200 and D300 wire rolls (D100 optionally available with magnetic adapter)
– Fine settings for voltage correction (in synergy mode), induction, arc length and post-flow time
– soft start for wire feed, feed button in the device
– high-quality MB 24 hosepack with Euro central connection and ergonomically shaped torch handle with ball joint
– stainless steel welding possible in standard MIG mode
– 2- and 4-cycle operation
– flux-cored wire welding
– spool gun interface

MMA functions (electrode welding)
– Weldable electrode diameters 2.5-5 mm
– Hot Start, Arc Force, Antistick and VRD

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 emits the set maximum current to prevent the electrode from sticking and annealing.
VRD: reduces the voltage applied during welding breaks. This minimizes the risk of electric shock if you accidentally touch the electrode.

Hot Start and Arc Force are adjustable.

TIG functions
– Lift TIG operation (DC)
