MIG/MAG, MMA, TIG Multiprocess welding system 3Ph - 230/400V 50/60 Hz (autosetting)
High-end MIG Synergic welding machine with customizable programs. Complete adjustment of all welding parameters




The JOB 635 LAB multiprocess inverter welding generator meets professional and specialist welding needs and is guaranteed by the LAB mark of excellence. Designed and built with care at our San Marino factories.

It allows to weld in Synergic MIG / Manual MIG / WIRE No Gas / MMA / TIG Lift with great precision.

The control of the generator is simple and intuitive while offering all the performances and adjustments of a professional welding machine.

The interface uses a color graphic display to make managing the generator extremely easy and pleasant.

It is extremely flexible: in synergic MIG mode, programs for welding many metals and alloys such as: steel, stainless steel, aluminum and brazing with copper silicon or copper aluminum wires are preloaded. Through the SD card it is possible to update and add new programs. The microprocessor memory also allows you to save customized programs as well.

In MMA mode it allows the welding of rutile and basic coated electrodes.

In TIG Lift mode it is perfect for precision work.

The body is designed with professional users in mind and with attention to detail such as, for example, sturdy rubber wheels, torch holder, accessories compartment, support for 50 L cylinders, etc.

The JOB 635 LAB model delivers 330 Amps in direct current. The power supply voltage is three-phase self-adjusting on 230/400 Volt.

The main features of the JOB 635 LAB are:


  • Robust 4 roller wire feeder diameter 37 mm.
  • Gas test function: to check the operation of the pressure reducer without advancing the wire.
  • Wire loading function: to easily load the wire into the torch without gas outlet.
  • Coil housing diameter 100 - 200 mm.
  • Synergic or manual regulation.
  • Preloaded programs for many materials.
  • SD Card Reader: to update programs and add new ones.
  • Personal program memory.
  • Inductance Adjustment: This value can be adjusted to reduce weld spatter.
  • Adjustable: Burn Back, Hot Start, Wire approach speed.
  • Welding modes: 2T / 4T / spot / stich.
  • Predisposition for use of spool gun or potentiometer torches.
  • Predisposition for Push Pull torches.
  • Predisposition for remote control by foot pedal or potentiometer.


  • Adjustable Arc Force: to obtain an optimal welding with each electrode it is possible to adjust the temporary increase of the current when the electric arc becomes short.
  • Adjustable Hot Start: to obtain an optimal arc ignition with each electrode it is possible to adjust the increase of the initial current.
  • Anti-sticking: allows you to easily detach the electrode if it remains glued to the piece.


  • TIG LIFT: arc striking occurs by touching the piece with the electrode and slowly lifting it. The risk of contaminating the workpiece with the tungsten electrode is small.
  • Automatic Slope up: progressive increase of the welding current to obtain a flawless start of the welding seam.
  • Adjustable Slope Up / Slope down: progressive increase and subsequent decrease of the welding current to obtain a flawless beginning and end of the welding seam.
