I'm sure you did right - 180 MXE's fetch up to £500. What age is yours? (first figures of the serial number contain the date) Other factor is whether it has the spot and stitch facility. They'll be shown on the cotrol panel, but are operational only if you have the relevant circuit board.
Hi Marty,
You can download the handbook for the Automig 180 MXE, and the parts list from Migatronic. Go to:
http://www.migatronic.com/login/welcome%20service%20site
and look for "OBSOLETE PRODUCTS WITH LIMITED SUPPORT"
So I just checked, and it looks as though they no longer do the 180 MXE...
Hi Mechman,
Here, thanks to the persistence of Dave C. of this list, is the circuit diagram of an early MX180 machine, which I think will be very similar to yours, if not identical. Certainly, it is of the 'discrete component' age, unlike later models, which although logically similar use...
Migatronics usually have very low minimum current settings. Mine (180 MXE) goes down to 20 amps. Worth checking before you assume it won't do this.
There is a circuit diagram for the early 180 which is based on discrete components. Sent to me by a member, and I've cleaned it up a bit to make...
I remember that, too. But I checked the date on both my cylinders - I think the 150-bar one was 2006, (cant remember the exact date, but it certainly wasn't 2014), the new one has 2011/06 stamped on it under SGS LTD. At least, I presume that is the date? My supplier did say that they'd had...
I just bought my first (10L) bottle the other day. I've had to wait a bit before using it, because my new-to-me Migatronic welder needed its PCB repaired, and this has taken longer than expected. Came back not working, should have come back again today, but didn't...
Expecting to be using it...
A little update - I learn from Migatronics that the three boards are as follows:
76116982 MPS-4TF Continuous welding, spot, stitch, latching, current control. Available @ £180.00
76116983 MPS Continuous welding, spot, stitch, the version you have I think, but this one is obsolete.
76116984 UPS...
I see 76116983 in the parts list for the MPS Std? This seems to be one of a series which are shared with the current Migatronic 183 (although while the -982 and -984 are listed, the MPS Std 983 is not. Do you know what MPS and UPS stand for?
Les at Technical Arc says the braking transistor...
Something of an update...
Dave on this list pointed out that the power for the wire-feed drive comes from the positive of the torch - obvious from the wiring diagram, but I hadn't spotted this. And when I replaced the (black) wire from the motor with a wire to the earth clamp the motor spun...
Hi Cager,
I've the circuit diagram for the 180 MXE, which I've tidied up a bit and made the wire colours coloured to make tracing easier. See below (I'd love a diagram of the control board if you've found one?):
Well, by wy of a start, I checked the voltage on the wire-feed motor (by removing the red and black lead and putting my meter in place of the motor):
After switching the machine on the voltage skittered around a bit (probably the meter autoranging around) and settled on about 500 mV. Pilled...
Hi Dave,
Could I also have a copy of the circuit diagram? I have an Automig 180 MXE which seems to have wire-feed trouble, despite a reconditioned board. My email is tony 'at' you-me-and-us dot com.
Meanwhile, I've made a clarified and coloured version of the Wiring diagram (as opposed to the...
Got the wire loaded, and connected the machine up for the first time...
I set the braking on the feed spool to what I thought might be a sufficient amount of drag - which required the nut to be wound in quite a way. Then I fed the wire through and tried to set it such that I could still push...
For nearby (surely not darkest?) Somerset:
So your Tech Arc has a similar feed-spool arrangement, with greased-plastic clutching elements loaded by a spring and nut? Surely the nut must be locked in some way, otherwise you'd get a birds-nest every time you stopped?
I've read somewhere about...
Hi, I've lately taken on an MXE 180. It came with a blown circuit board (now repaired) and missing a torch (4 Metre Binzel 150 bought) and a mains lead (found the correct rubber-sheathed cable to match original, and wired it in with a 16A plug. Annoyingly, the little Camloc catches for the...
