Hi Guys,
I'm just in the process of a small rebuild of my PCMIG135 (mainly Euro torch connector & Dinze Earth socket) - I've given up with trying to make the standard torch work with the Euro connector (splitting the power and gas was the problem) so I bought a MB-15, and I'm at a point where I need to wire in the gas solenoid (the gas connection is 6mm push-fit PU pipe - standardised throughout so this isn't a problem).
The solenoid valve I have is a 12V one and there's a 12V transformer/power supply system on the circuit board, but I don't know if it's got enough spare juice in it to run the valve (it takes about 6.5W or 540mA) or whether I should wire in a separate power supply for it? The transformer is a ZX7-DY2-A 12V model and the regulator is a W08, which I know can handle 2A - any of you geniuses out there know the answer?
I've got a separate high power (20A) 12V feed in the workshop (mostly for lighting) but I'd like the MIG to be self contained so as to make it a little more portable.
As part of the rebuild I've moved the power input to a 16A socket on the back panel and added a 16A outlet socket to daisy chain the CT-312 off it (plasma/MMA/TIG). I'd also like to build a gas mixer chest to allow differing ratios of the main gasses to be used for different metals (and between the MIG and the TIG) - this would save me a lot of space and hassle in having to have multiple gas bottles of different ratios, if I've designed it right then I can just dial in the flow rates for a particular mix and start welding (I'm planning to have a 'mixing chamber' where the gasses can merge and hopefully come out evenly). Does anyone else have any experience of this (am I wasting my time even thinking about it or is it a good idea?)
I'll see if I can put up a couple of photos of how I'm doing soon (if anyone's interested).
