STAHLWERK 3 in 1 Combination Welder CT 550 ST IGBT with Plasma Cutter

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!

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 parameters can be set individually and separately. They indicate how long before and after ignition 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 Argon 4.6 (99.996%). An arc is created in an argon bell between the tungsten electrode and the workpiece. This melts the material and any filler material that is supplied. A weld seam is created.
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.
