MIG-MAG/TIG/BRAZING/MMA Mastermig 275i welding machine, 3Ph, 400V, Telwin

MIG-MAG/TIG/BRAZING/MMA Mastermig 275i welding machine, 3Ph, 400V, Telwin

Product code: 816196

Brand: Telwin

This welding machine is a source of current for arc welding with 250A current, made specifically for MAG welding carbon steel or weak alloys with CO2 protective gas or Argon/CO2 mixes, using full or core electrode wires (tubular). It is also ideal for MIG welding stainless steel with Argon gas containing + 1-2% oxygen and aluminium and CuSi3, CuAl8 (brazing) with Argon gas, using electrode wires that are suitable for the workpiece to be welded.

Product description

The welding machine can be used for TIG welding in direct current (DC), with arc striking upon contact (LIFT ARC mode). It welds all types of steel (carbon, low- and high-alloy) and heavy metals (copper, nickel, titanium and their alloys) with a gas shield of pure (99.9%) Ar or, for special uses, with an Argon/Helium mix. It can also be used for MMA electrode welding in direct current (DC) using coated electrodes (rutile, acid, basic).

Key features

  • Dynamic display for monitoring and setting values
  • Can be used with 300mm reels, max. 15 kg
  • Adjustment of multiple parameters of the TIG welding torch. 2/4 stroke operation.
    • 2-stroke for quick and easy welding tasks, which allows an immediate stop when the trigger is released.
    • 4-stroke for longer, continuous welding jobs, where the process can be stopped with the second activation of the trigger, thus reducing user fatigue and improving the quality of the seam. 
  • Adjusting the reactance during MIG/MAG welding enables fine-tuning of the inductance of the welding circuit. By adjusting the reactance, the welder can optimize the behavior of the welding arc when welding different material thicknesses and types, improving the quality of welding and facilitating the welding process.
  • Particular construction of the ventilation system which, following a dedicated tunnel, allows preservation of the electronic components from dirt and dust.
  • Flexible use with various materials (steel, stainless steel, high strength steel, aluminium, galvanised sheet metal) and wide variety of application fields (sheet metal, maintenance, installation, bodyworks, etc..).
  • The Mastermig 275i is equipped with comprehensive protection features including thermostatic protection, overvoltage (+15%), undervoltage (-25%), overcurrent protection, and compatibility with motor generators (+/-15%), safeguarding the machine against potential damage and extending its service life.
  • Robust construction, resistant to impact and dust
  • Reduced weight and size.
  • High energy savings.

MIG-MAG
- Operating modes:
- 2T manual;
- 4T manual;
- Electronic reactance (INDUCTANCE), welding voltage and wire feeding speed adjustment.
- Set welding voltage shown on display.
- Set wire feeding speed shown on display.
- Welding current shown on display.

MMA
- Arc force (DYNAMIC ARC) and welding current adjustment. This helps maintain a stable arc even in difficult conditions, such as dense welds. With the Arc Force function, the inverter automatically adjusts the current depending on the length of the arc. If the arc accidentally touches the workpiece, the current increases, so it does not stick. If the two are too far apart, the current will be reduced and the arc will not extinguish.
- Set welding current shown on display.
- Welding voltage shown on display.
- Anti-stick protection.

TIG
- Welding current adjustment.
- Set welding current shown on display.
- Welding voltage shown on display.
- Start LIFT. The electric arc is struck by moving the tungsten electrode away from the piece to be welded. This strike mode causes less electrical-radiation disturbance and reduces tungsten inclusions and electrode wear to a minimum.

PROTECTION
- Thermostatic protection. A heat-sensing system that shuts down the machine if the temperature rises too high, preventing overheating.
- Protection against accidental short-circuits caused by contact between torch and earth.
- Protection against irregular voltage (power supply voltage too high or too low).

STANDARD ACCESSORIES
- MIG torch
- Return cable complete with earth clamp.
- Torch holder stand
