Thank you so much for your comments. It sounds very logical as the probes are indeed the original along with the rest of the insides of this machine (270 hours of on time). The entire module is offset by 50-75 degrees cooler so suspecting that the pe

You might consider buying a machine on eBay. I found a replacement the other day that came with xp. I think where it gets tricky is if you have the winkic software installed, as it is 16 bit software and seems to break on newer xp versions. There ma

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.

The nameplate specs for a 2004 Heller 1088EXL show 240V 60A, and specify Largest Heater Load of 25A. As each of the 8 heater elements is 6000W or 9.5R, how does this really work? Obviously all 8 elements on would pull 200A, so does the machine only

In no particular order: Will the failed joints wet when touched with an iron + flux? Is there flux surrounding the joint (post reflow). If no, you may be baking it out premateurely. Is this assembly wave soldered? Where is defect discovered in yo

| I have a recent design (1 component side only) that calls for 2 surface mounted antenna's (brass plated) to be mounted on a PCB. The problem arises when the PCB is 18x11.25 and has 15 to 20 PCB's in the pallet (IE weight, fixturing to hold the ant

Yep. If speed is not an issue a Heller 1500 will pretty well do you fine unless you are trying to process a brick. A Heller 1700 will not give you any more heated length, so don't get sucked in to that one. However, they are a little more fun to pl

I have a less than perfectly designed pcb requiring double sided lead free reflow. Several components from either side will detatch using the standard process. If I was using Sn63Pb37 I would just dispense some adhesive after paste and cure at the r

Hi. 1) recommend to phone up Heller for assistance on this case 2) using the wakeup profile, can you confirm if the problem remains or not when you skip the warm up of zone # 2? 3) each zone is based on 2 heaters (this is what we have on our 1809e
