SKU: 1042
GTIN: 4260294080423
Category: TIG DC welding machine with plasma cutter

The STAHLWERK CT-550 ST is a TIG and E-Hand combination welder with 200 Amp and 50 Amp plasma cutting function. The CT-550 ST is equally suitable for processing thin sheet metal and thicker sheet metal. Thus, the areas of application are very diverse. The 3-in-1 combination unit achieves a cutting performance of up to 12 mm with plasma cutting. Stainless steel sheets and metals with flash rust and paint can also be cut very well with the CT-550 ST. Despite its extensive functions, the CT-550 ST combination welder is powerful and reliable thanks to advanced IGBT technology. In addition to a comprehensive accessories package, the CT-550 ST - like all STAHLWERK units - comes with a 7-year warranty.

Device Funktions & Components

DC TIG welding – Direct current (DC). Welding of almost all materials such as steel, stainless steel, copper and many more.
Plasma/CUT – With electricity, a plasma jet is generated, which melts the material, which is then removed with compressed air. So all conductive metals such as e.g. steel, stainless steel, copper, aluminum, titanium and many more can be cut precisely.
Cutting power - Dividing cuts are possible depending on material up to 12 mm. Structural steel ST37 up to 12 mm, V2A or V4A up to 8 mm, aluminium up to 5 mm.
3 in 1 combined device – TIG and MMA welding up to 200A, plasma cutting up to 50A.
IGBT Technology – The latest and most modern transistor technology enables high performance welding! No transformer, no MOSFET, state-of-the-art IGBT!
Lightweight & compact design – only 7,5 kg and dimensions of 420 x 180 x 290 mm. Innovative IGBT transistors save space and weight compared to the old MOSFET technology. No heavy carrying!
Attention – Bottle connection: W21,8 x 1/14“ – Gas cylinders from the Netherlands and Great Britain may have a different connection! Please check the connections for compatibility before purchase!

Device Features & Benefits

HF ignition (TIG) – allows non-contact ignition and ensures a much better welding result. No LIFT ARC, no-stroke ignition!
Cutting current (CUT) – stepless adjustment from 15 to 50 A.
Air post-flow (CUT) – Automatic voltage increase upon the start for better ignition results.
Gas post flow (TIG) – protects the tungsten electrode against excessive wear and protects the weld from oxidation. The parameter can be set individually and separately. It indicates how long after ignition ends gas should flow.
Hotstart – Automatic voltage increase upon the start for better ignition results.
Anti-stick - Automatic shutdown of the welding current in case of sticking of the electrode which allows an easy removal. It also prevents annealing of the electrode.
Highest efficiency & performance – Single phase current (230 V) supplies the device and allows an output power of real 200 amperes.

Smart cooling & overheating protection – modern technology, built-in overheat protection and high-performance cooling allow you to get maximum performance.
TIG (Tungsten-Inert-Gas) – Inert gas welding with inert / inactive gases such as e.g. Argon 4.6 (99.996%). The glowing, non-consumable tungsten electrode causes the workpiece to melt and allows the addition of the filler material that forms the weld.
MMA / Stick electrode welding – an universal welding process. An arc causes the electrode to melt, forming the weld. No protective gas is needed.
Note:
- The unit is not intended for use in residential areas where power is supplied by a public low-voltage power supply system. It may be difficult to ensure electromagnetic compatibility in these areas due to both conducted and radiated interference.
