Hi All, I’ve been using my crossfire on and off since the Feb 2020 and have hooked it up to the Australian design Specialised Welding Supplies (SWS) Speedcut 50. It’s a great little unit and has been working perfectly so far and the SWS customer service is excellent!
The unit comes with an internal 4-pin plug (both halves) so you can tap into the fire circuit and THC capability. The THC is at 1:1, but SWS can supply a 50:1 voltage divider at extra cost.
I’ve cut some 6.35mm (1/4") mild steel plate and mainly thin sheet (1.0-1.6mm) and a kerf width of 1.5 that seems to work well up to the 1/4".
The thin sheet can be a bit tricky if not perfectly flat and as stress is relieved during each cut. This isn’t really a function of the Speedcut 50, but rather a thin sheet issue in general.
Here’s a link to their website: https://swswelding.com.au/
I’m not sure what the criteria is to add a cutter to the approved list, but this one is a safe bet.
I’ll get some pictures up of how I integrated the torch fire control soon.
