Today my aunt gave me a migatronic 5000 MX she found when clearing out my uncles outbuildings, he passed away last year. She was uncertain exactly when he got this machine but seem to think it was sometime late 80s early 90s, the welder was used to make a set of gates and then what to put in storage only being used a handful of times in the last 30 odd years. The power cable is perished on the outer armour but the wire insulation was fine so I taped it up but it wants changing imminently, only thing missing and trust me we looked everywhere is the euro torch, but I do have a spare which I fitted. I just had some new wire and coupled up a bottle to it, and did a little test run about 2 inches long and see some I'll spea about 2 inch long on a piece of Steel well with the wire feeder little and it was perfect. I did not push it longer than a couple of minutes the fact it had Sat untouched for so long in a cold brick building covered in had me a little concerned about the transformer or other electrical components having moisture in themthem, now I could well be overthinking this perhaps a little too cautious but I thought a couple of days in a warm dry building might help prevent any problems occurring. Logic tells me I am probably being a bit too careful because I think if anything has been majorly wrong it would have gone already in the first few seconds. So with a bit of background into this machine and its history, any thoughts or advice on what I should be looking at with regards to it being sad so long, and any preventative maintenance that could help me here would be appreciated. Also I have no manual on the machine it seems fairly simple to me if I've read the bit on the front properly it looks to be 2 it looks to be 25 150 amps but that is all I know about it Physically the only things I can see wrong ide physically the only things I can see wrong at the aforementioned cable and the paintwork could do with a bit of tidying up the top having no pain left at all the sides have fared better and everything is straight and solid, and I'm a well repainted just because I can. General thoughts and observations on this machine and any must do maintenance or specific idiosyncrasies please.
