Electrode Welding Machine - 250 A - 230 V - IGBT - 60% duty cycle
Manufacturer: Stamos Basic | Item number: EX10020135 | Model: S-MMA-250-I
At a full 250 amps, the welder can achieve a duty cycle of 60 percent. If the power is reduced to 194 A, the duty cycle is increased to the point where you can weld without interruption. The MMA welding machine does not require shielding gas, so you can work precisely even under adverse conditions, such as in high winds.
Show more Show lessThe welding current can be smoothly and precisely set between 20 and 250 amps—and the dial allows you to do so even when wearing welding gloves. The large LED display where the selected parameters are clearly visible offers maximum control for precise welding results.
Show more Show lessThe welding machine enables you to correctly install and maintain railings, stairs, gates, doors, containers or metal machinery. With the MMA welder, you can weld materials such as steel, iron, cast iron, nickel or copper from 0.5 mm thick.
Show more Show lessThe electrode welder's hot start function ensures an automatic and short-term increase of the welding current at the start of the welding process. This hot start optimally and instantly heats the weld at the starting point, which prevents the electrode from sticking and guarantees stable and clean welding results from the first moment.
Show more Show lessThe air cooling and overheat protection (displayed next to the control knob) guarantee the long-lasting functional reliability of this MMA welder. The device can be used nearly anywhere that can be supplied with electricity via a socket with a 230 V / 1-phase connector. The welding machine is equipped with a shoulder strap for convenient transportation.

Electrode Welding Machine - 250 A - 230 V - IGBT - 60% duty cycle
Powerful IGBT inverter technology, compact design and simple-yet-precise operation are the advantages with which the electrode welding machine S-MMA-250-I from Stamos Germany excels. The long-lasting 250 A make the electrode welding machine not only suitable for welding in the workshop or on the factory floor, but also for mobile repair and maintenance work outdoors.

- Instruction manual
IGBT = insulated-gate bipolar transistor. IGBT is a bipolar transistor with an insulated gate electrode. This semi-conducting device is being increasingly used in power electronics because it combines the advantages of two transistor types: the easy controls of the field effect transistor and the fast switching and high breakdown voltage of the bipolar transistor. The IGBT also offers some robustness against short circuits because it limits the electrical continuity. IGBTs are a further development of MOSFET technology.
Show moreShow lessPowerful fans ensure an optimal removal of heat from the unit.
On the back of every welding machine is a screw with an earthing mark. Before use, earth the unit via a cross-section cable, which must be at least 6 mm².
This device works with a 1-phase connection (230 V +/- 10 %).
Through automatically boosting the tension at the ignition of the arc, this function facilitates the electrical arc ignition. After ignition, the unit automatically returns to the pre-set voltage.
