MIG/MAG welder Paton StandardMIG-250

Basic data of the Paton StandardMIG 250 MIG/MAG welder

The digital Paton StandardMIG 250 MIG/MAG MMA/TIG Lift welder is intended for semi automatic arc welding in the MIG/MAG process, for gas shielded arc welding in the TIG process and for manual arc welding with covered electrodes in MMA, with direct current (DC) and with the option of using the PULSE function.

Machines in the "Standard" series are meant for home and semi industrial use. The PSI 250S holds a 45% duty cycle at the full rated current of 250A with no loss of output or weld quality. A solid build and simple operation make work with the machine trouble free, and despite the small size of the welder it gives very good weld quality. The fully electronic control used in this series rules out the weak points typical of multifunction systems. The power source comes set to sensible values, so you can start work with it straight away. For more advanced jobs the unit has been given additional functions. A mark of the PATON™ Standard series semi automatic welders is the high quality wire feeder, which has been additionally sealed, and the KZ-2 central connector of the "EURO" type, which has become a worldwide standard and lets the user fit whichever MIG/MAG torch they prefer.

Functions and capabilities of the versatile Paton StandardMIG 250 MIG/MAG welder

GASLESS WELDING FUNCTION, WELDING WITH SELF SHIELDED WIRE
All PATON MIG/MAG welders are prepared for welding with self shielded wire. Unlike the standard MIG/MAG process, this kind of welding runs without shielding gas, but it does call for a special welding wire. Such wire produces its own shield, which helps to protect the welding arc.

BRAZE WELDING, INDUCTANCE ADJUSTMENT

Paton MIG/MAG WELDERS of the Standard and PRO series can be used for braze welding thanks to a three step inductance setting. Inductance control lets you match the arc characteristic to the thickness of the workpiece. The 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 for thick parts the opposite applies (hard arc, deeper penetration).

PULSE FUNCTION IN EVERY PROCESS

PULSE in the TIG process, full control of the heat put into the material, a very useful function for welding stainless and acid resistant steel,

PULSE in the MMA process, easier transfer of material from the electrode into the weld pool, better quality of the welded joint,

PULSE in the MIG/MAG process, easier detachment of the metal droplet from the end of the electrode wire, with adjustable pulsed current parameters. Pulsed MIG welding is useful on stainless and acid resistant steels and on aluminium alloys. Pulsed welding also gives better parameters in CuSi3 braze welding

MAIN DIFFERENCES BETWEEN THE STANDARD AND PRO SERIES MIG/MAG WELDERS:

• duty cycle, welders of the Standard series have a 45% duty cycle, while the PRO series has a 70% duty cycle at the same welding current. PRO series welders also reach continuous duty at a higher welding current than Standard series machines.
• wire feeder, the PRO series has a separate wire feeder that takes spools from 15 to 18 kilos. The feeder can be detached from the power source for easier welding in other processes, for example MMA or TIG DC. The PRO series also comes in 2 roll and 4 roll feeder versions. In Standard series welders for a 230V supply the feeder is built into the machine, takes only spools up to 5 kilograms and always has two rolls.

Main advantages of the Paton StandardMIG 250 MIG/MAG welder:

• European manufacture
• Electronic thermal protection system that protects every heat generating part against overheating
• Reliability thanks to IGBT technology
• Can be run on long extension leads and from a generator
• Welding with pulsed current in every welding process
• Improved stability of the electric arc

• 2T and 4T mode switching, gas purge from the feeder function

• The machines have protection against voltage surges and a stabilising circuit, which allows correct operation over a voltage range from 160V to 260V
• Half the demand for electrical energy compared with conventional power sources
• Sound fusion and a correct bead shape regardless of welding position

5 year manufacturer warranty for consumers and for companies

Top build quality confirmed by a 5 year DOOR-to-DOOR manufacturer warranty. Models of the STD series carry a number of design solutions that raise their reliability. These include the sealed, trouble free wire feeder, the central connector of the KZ-2 EURO type and the built in voltage stabilising module.

The set you buy contains:

• Inverter welder PATON™ StandardMIG-250 230V
• Electrode holder 3m
• Earth clamp 3m
• Wire feed rolls 1x (0.6-0.8), 1x (1.0-1.2) V
• Quick gas coupling

Compared with inverter welders from other makers, this product, created by the designers of the Welding Equipment Department of the E.O. Paton Electric Welding Institute, has the following advantages:

• Broad adjustment of welding parameters:
  , MMA process, 1 (basic) + 10 (additional)
  , TIG process, 1 (basic) + 4 (additional)
  , MIG/MAG process, 2 (basic) + 4 (additional)
• Welding with pulsed current, which is also programmable, in all welding modes.
• A system that protects against voltage surges.
• Besides the protection against voltage surges, a stabilising circuit has been fitted for larger long term voltage differences in a single phase mains supply, 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 ø3 mm, or run semi automatic welding with wire no larger than ø 0,8 mm.
• Matched to a standard power network. Thanks to high efficiency the power source needs half the electrical energy compared with conventional sources.
• Adaptive fan speed, which rises at the start of welding, rises further when the welder is hot and falls when it is cool, which saves the fan and reduces the amount of dust inside the machine.
• Comfortable work thanks to the long load time at rated current, which allows welding almost without a break using ø5 mm electrodes (for the PSI 250 Standard), for example ANO-/21/36 at a current of 200 A at a temperature of 25 °C.
• Higher reliability of the welder in production conditions with heavy dust and high humidity. The microelectronic circuit has been moved into a separate chamber protected by a solid structure.
• Longer life thanks to impregnation of the electronic circuit with two coats of high quality varnish, which keeps the product dependable throughout its service life.
• The welder has an electronic thermal protection system that protects every heat generating part of the welding unit against overheating.
• Improved stability of the electric arc.
• Stepless adjustment of welding parameters.
• Efficiency thanks to the use of the latest advanced IGBT technology.
