MIG/MAG Welding Machine - 250 A - 400 V - duty cycle 60% - with cart
Manufacturer: Stamos Basic | Item number: EX10020021 | Model: S-MIG 250
The full 250 amp power results in a duty cycle of 60 percent with which even difficult repair and renovation work can be reliably mastered. The welding current and the corresponding voltage are determined using a rotary control; both values are clearly displayed on two separate LED displays. The MIG/ MAG welding machine is designed for all metalworking projects in production, workshops, metalworking shops or trades.

The resulting constant wire feed enables welding work to be carried out with maximum accuracy—which can also be exactly repeated during subsequent welding work with exactly this controller setting. In addition, you can effortlessly switch between 2-stroke and 4-stroke using a toggle switch.
Show more Show lessDifferent shielding gases are used in MIG and MAG welding, making it possible to process various materials. In MIG welding, inert gases are used for copper, magnesium and other non-ferrous metals and their alloys; MAG welding with active gases is optimal for structural steel, steel and most of their alloys.
Show more Show lessThe compact design of the technical interior in a stable metal housing protects the device from mechanical damage. The device is also mounted on a cart with front wheels that swivel 360 degrees for optimal mobility. Above the rear wheels there is a storage area on which a gas cylinder can be conveniently placed and secured with a chain.
Show more Show lessThe device is cooled with a powerful fan whose efficient air circulation protects against overheating and thereby contributes to the longevity of the welder. The cooling system is supported by the illuminated display on the front of the welding unit. The warning light provides information at a glance about malfunctions or when standard operating cycles have been exceeded—one of the main causes of unwanted temperature peaks.

The MIG/MAG welding machine S-MIG 250 from Stamos Germany with proven, reliable and powerful technology is a true all-rounder in metalworking and processing. The infinitely variable regulation of the welding current in the very broadly defined range between 50 and 250 amps guarantees maximum flexibility for every requirement of efficient welding with the optimum heat at the welding seam.

- MIG torch 4 m
- Ground cable with clamp, 3.5 m
- 3 contact tips (1 x 0.8 mm, 2 x 1 mm)
- 2 gas nozzles
- Instruction manual
The welder is equipped with a MOSFET transistor. This technology represents the highest standards of performance combined with compact and lightweight design. The result is 93% efficiency! The welding current is very stable and thus ensures a perfect weld.
Show moreShow lessPowerful fans ensure an optimal removal of heat from the unit.
TIG/MIG and MAG welding require a protective gas. Inert gases, such as argon and helium, as well as active gases (for example carbon dioxide) and other mixtures can be used. The solenoid valve regulates the flow of gas. The valve is operated via a button on the torch.
Show moreShow lessOn 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 3-phase connection (400 V +/- 10 %).
Start the weld by placing pressure on the torch button. Stop the process by releasing the button.
By pressing the torch button the solenoid valve opens. allowing the gas to flow in. The gas pre-flow ignites the arc at the pre-set current. Releasing the burner button initiates a rise in the current to that of the pre-set welding current. The welding process stops once you press the burner button again.

What shielding gas can I use for this welding machine?
For MIG welding you will need inert gases such as argon or helium, while for MAG welding you need active gases such as carbon dioxide.
Is there a warning when the device is threatening to overheat?
There is an indicator light on the unit that warns you if a malfunction occurs or if the permissible duty cycle has been exceeded. In both cases you should interrupt the welding process and wait until the warning light goes out. Only then can you continue welding.
Bin sehr zufrieden......das einzige Manko ist gewesen das das Stromkabel zu kurz ist ....hab aber gleich ein längeres montiert jetzt ist alles super.....

Danke für Ihr positives und hilfreiches Feedback.
Wir freuen uns auf ein Wiedersehen. Bis bald und einen schönen Tag noch!
Zeer tevreden over de verkoop en service .
Die Lieferung kam einen Tag später an als angekündigt. Die Ware war sehr gut und stabil verpackt, beim Zubehör fehlen jedoch das Schutzschild und der Schlackehammer, was aber zu verschmerzen ist, für mich jedenfalls. Das Schweißergebnis ist für eine Maschine dieser Preisklasse überraschend gut, ruhiger und stabiler Lichtbogen, kaum Spritzer in allen getesteten Schweißpositionen, überkopf, waagrecht und steigend. Wünschenswert wäre es die eingestellten Parameter direkt am Display zu sehen, diese werden jedoch nur während des schweißens angezeigt. Aufgrund des guten Schweißergebnises und des guten Preises trotzdem zu empfehlen.
