SMT line expansion - new oven and selective solder

If your ovens are 480V you may be able to convert them back to 240V by changing out the elements? There are industrial suppliers for oven elements out there. sarason

So do you guys really not like running oven's this large at 240V? Or do you just not like the two ovens specifically that I mentioned?

FYI, in my experience, programming and fine tuning select solder is usually quick and painless.

Oh no, it's rated at a max of 120A at 208V. We have the power for that. At least the Vitronics is, not sure on the Heller.

In my experience Heller makes a great, no frills oven that just runs. The only Vitronics oven I've dealt with was over-engineered and gave me nothing but headaches.

What we did not talk about is Mycronic machine. Great choice for small batches.

We have 3 Heller 1800 units. They run great. Our building is 208 3ph. One of ours is running 480v, so we bought a transformer to convert. I am not familiar with the other oven you mentioned.

You might be able to get a step up transformer although I would not recommend that unless it is a good solution for you. What is the input voltage to your facility? It is probably 600V (or something close). If so then you could get a step down transf
