STAHLWERK CT550 ST, compact TIG MMA welder with plasma cutter, up to 12mm, 200 amp TIG MMA 50 amp CUT (no ALU welding)

SKU: 1041-001
GTIN: 4260294080416
Category: WIG DC welding machines with CUT

The STAHLWERK CT-550 ST is a TIG and MMA combination welder with 200 ampere and 50 ampere plasma cutting function. The CT-550 ST is equally suitable for processing thin sheet metal and thicker sheet metal. The areas of application are therefore very diverse. The 3-in-1 combination device achieves a cutting performance of up to 12 mm during plasma cutting. The CT-550 ST is also ideal for cutting stainless steel sheets and metals with rust film and paint. Despite its extensive functions, the CT-550 ST combination welder is powerful and reliable thanks to its advanced IGBT technology. The CT-550 ST is supplied with an extensive accessory package.

Device functions & components

DC TIG Welding - Direct Current (DC). Welding of almost all metals, such as steel, stainless steel, copper and many more. Note: Not suitable for aluminum - this requires an AC/DC unit.
Plasma / CUT - A current is used to generate a plasma jet that melts the material, which is then removed with compressed air. In this way, all conductive metals such as standard steel, stainless steel, copper, aluminum, titanium and many more can be cut precisely without any effort.
Cut thickness - cut-offs are possible up to 12 mm depending on the material. Mild steel ST37 up to 12 mm, V2A or V4A up to 8 mm, aluminum up to 5 mm.
3 in 1 combination unit - TIG & MMA welding is possible up to 200A, plasma cutting up to 50A.
IGBT Technology - Latest and most advanced transistor technology enables high power welding! No transformer, no MOSFET, state of the art IGBT!
Lightweight & compact design - only 7.5kg weight and dimensions of 420 x 180 x 290mm. Innovative IGBT transistors save space and weight compared to old MOSFET technology. No more heavy carrying!

Device features and advantages

HF ignition (TIG) - enables non-contact ignition and provides a much better welding result. No LIFT ARC, no strike ignition!
Contact Ignition (CUT) -High frequency (HF) contact ignition for first class ignition performance. A brush over the workpiece is sufficient.
Cutting current (CUT) - Stepless adjustment from 15 to 50 A.
Air after-run (CUT)-After cutting is complete, air flows in to cool the torch and reduce nozzle and electrode wear.
Gas after-run (TIG)-protects the tungsten electrode from excessive wear and protects the weld from oxidation. The parameter can be set individually and separately. It specifies how long gas should flow after ignition.

Hotstart - Automatic voltage increase at start-up for better ignition results.
Anti-stick - Automatic shutdown of the welding current when the electrode sticks allows easy removal.
Highest Efficiency & Power - Single phase AC power (230V) supplies the unit and allows output power of true 200 amps.
Smart Cooling & Overheat Protection - State-of-the-art technology, built-in overheat protection and high-performance cooling allow maximum power to be retrieved.
TIG (Tungsten Inert Gas) - Gas shielded welding with inert/inactive gases such as Argon 4.6 (99.996%). An arc is created between the tungsten electrode and the workpiece in an argon bell. This melts the material and any filler material added. A weld seam is formed.
MMA electrode welding / ARC welding - a universal welding process. An arc causes the electrode to melt, forming the weld. No shielding gas is required.
Note::The device is not intended for use in residential areas where the power supply is provided by a public low-voltage supply system. It may be difficult to ensure electromagnetic compatibility in these areas due to both conducted and radiated interference.
Note: The connection may vary depending on the rod electrode. Therefore, please observe the connection specification of the type of rod electrode used! When welding common DC electrodes, the connection is made as shown on the welding device. When processing DC+ electrodes, the connections must be exchanged.
