Paton MultiPRO 250 (15-4)

Paton MultiPRO 250 (15-4) MIG/MAG MMA/TIG HF welding machine, basic data

The digital multifunction inverter welding machine PATON^® MFI 270 MULTIPRO 230V is intended for semi automatic welding with the MIG/MAG method, manual arc welding with the MMA method and arc welding with the TIG HF method under shielding gases and mixtures with direct current. Machines of the MultiPro series have a module for contactless arc striking (oscillator) with a built in gas inlet valve.

The fully electronic control system used in this machine rules out the drawbacks typical of multifunction machines built on analogue control systems, which by definition are always aimed at one particular method, while all the remaining methods are added on and suffer from control weaknesses. In a fully electronic system the control unit has absolutely all the resources of the power source at its disposal, within its full output and regardless of which method is used. The machine of the „Multi-Professional” series is intended for industrial use, and the power source can be separated from the wire feeder for convenience of use as well as for safety.

The additional settings let you pick the welder setup that fits the job best. The power source delivers a rated current of 250 A, which is enough for work with electrodes from ø1.6 mm up to easily melting ø6 mm, and for semi automatic welding with solid wire from ø0.6 mm to ø1.2 mm. The source comes set to optimal values by default and is simple enough as long as you do not go deep into the detailed settings, which already call for more experience from the welder. For hazardous working conditions a block that lowers the open circuit voltage in the MMA method is built in, with the option to switch it on and off.

A feature typical of the PATON^® „Multi-Professional” series welding machines is the good quality sealed metal wire feeder, along with the KZ-2 connector of the „EURO” type, which has become a world standard and lets the user change the torch later as they see fit. The machine has a protection module against an incorrect level of supply voltage (surges or voltage drops) as well as against overvoltage. Because of the raised frequency of the voltage fed to the transformer, the transformer can be several times smaller. That is why the weight and the overall dimensions of the welder are several times smaller than those of ordinary machines with identical output parameters.

Functions and properties of the Paton MultiPRO 250 (15-4) MIG/MAG MMA/TIG HF welding machine

GASLESS WELDING FUNCTION, WELDING WITH SELF SHIELDED WIRE
All PATON welding machines are prepared for welding with self shielded wire. Unlike the traditional MIG/MAG welding process, such welding is done without shielding gas, but it does call for a special welding wire. That wire produces its own shield, which helps to protect the welding arc.

MULTIPRO SERIES, BUILT IN IONIZER

Welding machines of the MultiPro series have a built in HF IONIZER, which allows contactless arc striking in the TIG method. This extension is a function of the TIG torch control button. The torch button control lead is connected directly to this module. After the control button on the torch is pressed, the control signal goes to the machine controller, which runs the pre gas flow function t1 to clean the weld area before welding, then passes the signal to switch the machine on with a delay, so that welding in the TIG method with contactless arc striking is possible.

BRAZE WELDING, INDUCTANCE SETTING

Paton welding machines of the Standard and PRO series can be used for braze welding thanks to the function that changes the inductance in three steps. Inductance control allows the arc characteristics to be matched to the thickness of the welded part. This function is needed to change the rate of current flow when the arc voltage changes. The thinner the part to be welded with MIG/MAG, the higher the inductance should be (soft arc, shallower penetration), and the other way round for thick parts (hard arc, deeper penetration).

MAIN ADVANTAGES OF PATON^®:

1. 1. Broad setting of the welding parameters
      a) the MMA method, 1 (basic) + 10 (additional)
      b) the TIG method, 1 (basic) + 10 (additional)
      c) the MIG/MAG method, 2 (basic) + 8 (additional)
   2. Pulsed current welding mode available in all methods;
   3. Besides protection against mains voltage surges, the machines have a work stabilisation circuit for longer voltage changes in the single phase mains supply and allow correct work of the machine over a voltage range from 160 V to 260 V. Keep in mind that at the minimum voltage of 160 V you can weld with an electrode no larger in diameter than ø 3 mm, or do semi automatic welding with wire no larger in diameter than ø 0.8 mm.
   4. An installed module for contactless striking of the electric arc in the TIG DC method (the arc is started with high voltage in the kV range)
   5. The welding machine is matched to the standard mains supply. Thanks to its high energy efficiency the source gives twice lower electrical energy demand compared with traditional sources;
   6. Adaptive control of the fan speed, the fan runs harder when the machine is hot and slows down when the machine is not in use. That affects fan wear, cuts the amount of dust inside the machine and the noise during welding.
   7. Comfort of work thanks to the long duration of loading at the rated current, which allows practically uninterrupted work at a temperature of 25 °C.
   8. High reliability of the machine in production conditions with heavy dust and high humidity.
   9. The machine has a thermal protection system that guards all heat generating parts of the welding unit against overheating.
   10. All electronic parts of the machine are impregnated with two layers of quality varnish, which keeps the product reliable through its whole service life;
   11. Improved stability of the electric arc, which practically rules out sticking of the electrode.
   12. When the power source is separated from the wire feeder it stays small in size and the machine is mobile, which makes welding in hard to reach places simpler.
