Main highlights

Versatile material processing – with AC/DC TIG welding, almost all metals such as steel, stainless steel, aluminium and copper can be welded. The CUT function allows precise cutting of conductive metals such as standard steel, stainless steel, copper, aluminium and titanium.
Precise plasma cutting function – a plasma jet is generated by means of electricity, which melts the material and removes it with compressed air. Depending on the material, cutting cuts up to 12 mm are possible, including mild steel ST37 to 12 mm, V2A or V4A up to 8 mm and aluminium up to 5 mm.
Modern technology and comfort – IGBT technology, RF ignition, 2T/4T control, smart cooling and overheating protection ensure efficient work. Weighing only 15.65 kg and measuring 507 x 238 x 437 mm, the device remains lightweight and compact.
Comprehensive pulse function – the TIG pulse function facilitates the welding of thin sheet, prevents the burning of materials and reduces heat-related deformation. Adjustable pulse current, pulse width, pulse frequency as well as long and short pulse.
3-in-1 combination device – The STAHLWERK AC/DC TIG 200 Pulse Cut ST combines TIG welding, MMA or electrode welding and plasma cutting in one compact device. TIG and MMA are possible up to 200A, plasma cutting up to 45A.
