The high-performance MIG/MAG welder with 250 A and 60 percent duty cycle

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.

In addition to the welding current, the 4-roller wire feed of the welding wire is also set simply and precisely via the rotary knob. 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.

Different 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.

The 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.

The 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.

Instruction manual

MOSFET

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.

VENTILATORS

Powerful fans ensure an optimal removal of heat from the unit.

PROTECTIVE GAS

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.

EARTHING SYSTEM

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.

GROUND TERMINAL CONNECTOR

MIG/MAG TORCH CONNECTOR

SUPPLY VOLTAGE

This device works with a 3-phase connection (400 V +/- 10 %).

WELDING CURRENT

2-STROKE

Start the weld by placing pressure on the torch button. Stop the process by releasing the button.

4-STROKE

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.

OVERLOAD / FAULT LED

The LED light indicates overheating or a malfunction.

The diverse assortment of products from Stamos enable you to cut or join materials efficiently and precisely. Our portfolio ranges from professional soldering stations to top-class welding machines and precise plasma cutters, to the matching accessories. Let us demonstrate to you the functionality, quality and versatility – not to mention the cost-effectiveness – of our professional line. Our videos show our products in action.

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.

Reviews from Amazon Customer (23 Mar 2018) Stamos S-Mig 250

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.
