Features & Advantages of the Stahlwerk CTM 250 Combination Welding Machine

• TIG (Tungsten Inert Gas) – Shielded metal arc 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 produced.
• MMA electrode welding / ARC welding – a universal welding process. An arc causes the electrode to melt, forming the weld seam.
• Hotstart – Automatic voltage increase at start-up for better ignition results.
• Anti-Stick – Automatic shutdown of welding current when the electrode sticks, allowing easy removal.
• MIG/MAG – Metal arc welding with direct current (DC). Welding can be done with inactive/inert (MIG, e.g. argon) or with active (MAG, e.g._CO2) gases. Gas and welding wire come out of the torch head, allowing welding to be done with only one hand.
• Flux-cored wire – all our ST series units can use flux-cored wire. This allows welding without shielding gas. For this purpose, the unit can be reversed particularly easily.
• Automatic wire feed – the speed of the wire feed is automatically controlled by the set welding current and also by the selection of the used wire thickness on the device.
• Current voltage (volts) – variable voltage control to manually adjust the burn-in and burn-off of the wire. Thus, it is possible to act on the different properties of a wide range of materials.
• 4 roller drive – reliable and powerful wire feed. Thanks to 4 drive rollers, even thicker wires are fed continuously and safely.
• Manual wire push-through – no more gas loss or laborious pushing of the wire through. If a new wire reel is to be fed through the hose package, this is done completely automatically with the wire push-through button.
• Wire reel – Commercially available wire reels from 1 kg to 5 kg can be processed here. The spool mandrel can accommodate 16 mm & 50 mm spools.
• Wire Drive Roll – By simply changing the drive roll from 0.6 mm, 0.8 mm, 1.0 mm & 1.2 mm, different wire thicknesses can be used.
• Plasma / CUT – A plasma jet is generated by means of electricity, which melts the material, which is then removed by 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 14 mm depending on the material. Mild steel ST37 up to 14 mm, V2A or V4A up to 8 mm, aluminum up to 5 mm.
• Contact ignition – High frequency (HF) contact ignition for first-class ignition performance.
• Cutting current – Stepless adjustment from 15 to 50 A.
• Air Run-On – Infinitely adjustable air run-on from 3 to 10 seconds to cool the torch and reduce nozzle and electrode wear.
