Electrode Welder - 250 A - IGBT - 80% duty cycle
Manufacturer: Stamos Pro Series | Item number: EX10020019 | Model: S-MMA-250-PI
At a full 250 amps, the welder can achieve a duty cycle of 80 percent. If the power is reduced to 220 A, the duty cycle can be increased to the point where you can weld without interruption. With its high performance, the welder can even weld thicker metals up to 10 mm quickly and precisely.
Show more Show lessThe welder is equipped with an 8 metre-long MMA cable and earth cable, which together correspond to a product value of approx. €50 and are four times the length of standard welding cables. The unique range of the cable assembly gives the device maximum flexibility while welding. You can also use it even under adverse conditions, such as in high winds, because MMA welding does not require shielding gas.
Show more Show lessThe arc welder is equipped with practical and cutting-edge features such as an IGBT inverter, which enables you to quickly produce clean, safe welds with little effort. You can smoothly and precisely set the welding current to between 20 and 250 amps using the control knob.
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 1.5 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.

- 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.

Tester en rutile 1.5 et en rurile de 4 de 60a à 200a pour tester il fait de belle soudure et a 200a sur de la tole de 100mm sa crache j'ai même exagéré pour voir il a vraiment de la puissance je ne suis meme pas monter a 250a car a 200a sa fait déjà trop de projections en baguette de 4 il m'aurait fallu une baguette en 5 pour le tester à fond.
Par contre deux remarques :
- visses déjà rouillées sous le poste donc stockage à revoir.
-colis avec un impact interne non visible à l'extérieur, le polistyren est casser et le plastique de la façade du poste aussi mais bon je l'ai recoller il soude trop bien je le garde malgré tout
Funktioniert mit 16 A Steckdose einwandfrei einziges manko sind die Schweißkabel sind aus Alu ohne Aderendhülsen mit dem Elektrodenhalter verschraubt die ummantelung ist nicht hitzebeständig außerdem sollte man auch offen den Hersteller angeben Polen !ag9yE
