Category: Sale

The STAHLWERK CTM-250 ST is a combination welding machine that covers the TIG, MIG/MAG, MMA and MMA processes and has a 200-amp and a 50-amp plasma cutting function. One of the many advantages of this multifunctional device is that numerous welding and cutting parameters can be set individually. The device is suitable for processing thin sheet metal and for flux cored wire. CuSi3 soldering is only possible in TIG mode. When plasma cutting, the 4-in-1 combination device achieves a cutting capacity of up to 14 mm. The CTM-250 ST is also very good at cutting stainless steel sheets and metals with rust film and paint. Despite its numerous functions, the CTM-250 ST is very compact and is powerful and reliable thanks to its advanced IGBT technology. The CTM-250 ST is supplied fully equipped with an extensive accessories package.

Functions

DC TIG welding - direct current (DC). Welding of almost all metals, such as steel, stainless steel, copper, brass and many more. Note: Not suitable for aluminum - this requires an AC/DC unit. 4 in 1 combination unit - TIG + MIG/MAG + MMA / E-hand welding up to 200 A possible and 50 A plasma function.
2T/4T (TIG/MIG/MAG) - determines mode control and provides advanced control over current flow. In 2T mode, high frequency (HF) ignition remains active until the button on the torch is released. In 4T mode, pressing and releasing the button once ignites the arc. After pressing and releasing again, the ignition is terminated.
Gas follow-up (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.
Lightweight & compact design - only 14 kg weight and dimensions of 450 x 250 x 350 mm. Innovative IGBT transistors save space and weight compared to the old MOSFET technology. No more heavy carrying!
HF ignition (TIG) - enables non-contact ignition and provides much better welding results. No LIFT ARC, no strike ignition!
Highest efficiency & power - single phase AC (230 V) powers the unit and allows output power of true 200 amps for TIG + MIG/MAG + MMA.
Smart Cooling & Overheat Protection - State-of-the-art technology, built-in overheat protection and high performance cooling allow maximum power to be retrieved.

Features & Advantages

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 feed - no more loss of gas or laborious pushing of the wire through. If a new wire reel is to be fed through the hosepack, this is done completely automatically using the wire feed button.
Wire spool - Commercially available wire spools from 1 kg to 5 kg can be processed here. The spool mandrel can accommodate 16 mm & 50 mm spools.
Wire drive roll - different wire thicknesses can be used by simply changing the drive roll from 0.6 mm, 0.8 mm & 1.0 mm.
Plasma / CUT - A plasma jet is generated by means of electricity, which melts the material, which is then removed with compressed air. This allows all conductive metals such as standard steel, stainless steel, copper, aluminum, titanium and many more to be cut precisely and effortlessly.
Cutting thickness - Depending on the material, cuts of up to 14 mm are possible. 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 behavior.
Cutting current - Infinitely variable adjustment from 15 to 50 A.
Air after-run - Infinitely adjustable air after-run from 3 to 10 seconds to cool the torch and reduce wear on the nozzle and electrode.

Note: The appliance is not intended for use in residential areas where power is supplied via a public low-voltage supply system. It may be difficult to ensure electromagnetic compatibility in these areas due to both conducted and radiated interference.
