Powerful combined welder for all common welding situations
The powerful professional combined welder S-MULTI 300 from Stamos Germany proves itself with its universal applications and high-quality welds with a low error rate. Whether you are welding with or without shielding gas, the combined welder's four welding methods, MIG/MAG, TIG, MMA and FCAW, offer the perfect solution for every welding situation.
The combined welder's digital menu navigation facilitates precise welding values
With a duty cycle of 60 percent, the welding current has a maximum power of 300 A. If you turn the power down to 230 A, then you can weld without interruption. The clearly arranged control panel with two LED displays gives you maximum control over the required welding parameters and is also easy to use while wearing welding gloves. You can freely adjust the amperage and the voltage (MIG), specify the inductance, switch between 2-stroke or 4-stroke operation, or choose the welding process you require.
MIG/MAG - fast, effective and universally-applicable
When it comes to MIG / MAG welding, the welding seam is protected with gas: inert gas for MIG welding, and active gases for MAG. You can easily specify the inductance via a control knob when MIG/MAG welding. Other knobs allow you to set the wire feed between 2.5 and 24 m/min and set the welding voltage. For aluminium welding, we recommend using the spool gun SP-01-3M, also available from Stamos Germany.
FCAW - weld smaller metal work with flux-cored wire
FCAW welding produces a weld seam by means of a cored wire, without the need for additional gas as protection. Its versatility makes it suitable for a wide range of small metalwork, repairs or base welding work on cars.
TIG - tried and tested with cutting-edge lift-arc ignition
The S-MULTI 300's TIG welding process uses gentle lift-arc ignition to activate the arc, which can be used even in the presence of sensitive electronic devices such as computers and control systems and which is distinguished by fewer ignition problems. You can easily control the TIG welding values via the control panel.
MMA - flexible electrode welding without extra gas
No additional gas is required for MMA (Manual Metal Arc) welding, enabling you to use it outdoors even in strong wind. The arc force and anti-stick functions ensure optimal welding results. The VDR function can be enabled for increased security through voltage reduction, especially when you need to weld in damp environments.
The MMA welding machine is equipped with an undercarriage which makes it especially easy to transport. There is space above the rear wheels for a gas cylinder which can be secured with a bracket and two chains.

Does this device have anti-stick?
Yes, the device falls back on anti-stick during MMA welding to prevent the electrode from sticking.
I'm looking for a welding mask, can I get them from expondo?
You can find a wide selection of welding hoods from expondo under "Welders", in the subcategory "Welding Accessories".
