I will be happy to buy one of them. We purchased a used 1800EXL just recently and it did not come with any manuals. I will appreciate any help you can provide. I can be contacted at (954) 424-4554. Best regards, Aybars Ocal

Thank you Bilal, i am aware that you can't run 3x240 machine at 3x380V, that is why i have delta-delta transformer. It was phase sequence after all, and machine is now running. Thank you all for your help.

1. Why isn't an electrician doing this? 2. Did you measure phase-to-phase voltage between each phase at the machine? 3. Phase rotation only affects the 3-phase motors. If it's out of sequence, the motors will spin backwards but everything else sho

If machine serial tag referring to 3Ph, 208-240V then you cannot apply 3Ph, 380V. In order to use 3Ph, 380V supply you have, machine needs to be retrofitted to work with this voltage. If you apply 380V without voltage conversion, you will damage som

I am wondering if anyone has had issues with their Heller oven rails warping. It appears that our 1800EXL and 1900W oven rails sag after time. They eventually contact the safety mesh and then create hestitation of the chain, thus creating defects.

hello everyone, I got a Heller reflow oven that operates at 3x240V and a delta-delta transformer since my grid is 3x380V. the problem I have right now is that there is no neutral line at delta-delta transformer, also there is no neutral line at oven

Good Morning SWAG, We have had similar problems with our Heller 1800 EXL's when the chains would build up oil and debris. The only way we could get them clean was to put them into a self cleaning oven and carbonize the residues. We then rinsed them

We just bought a new Heller 1800 EXL reflow oven for reflowing SMT boards. We us a low temp RMA solder paste with 2% silver. Everything we build is to IPC Class 3 specifications. We have approximately 600 different types of circuit boards we build

We have the same issue. It was present with our old 1500 and is even more present with our newer 1800EXL. For us, it seems to be related to the blowers, not the heaters. If we are in cooldown or wakeup the issue is still there with the heaters off.
