Hi all, We run an old Seho 1135C wave solder with a 63/37 pot at 250°C. It has been running well for a couple of years but we have noticed lately that all of the larger pads (terminal blocks, transformers, etc.) require additional solder to be appli

We're not sure the specifics that BLT Circuit Services Ltd referenced, but many companies use dross reducing agents in their wave solder pots. Among dross reducing agent suppliers: * Fry [4100 Sixth Ave, Altoona, PA 16602; 814-946-1611 F814-944-8094

Florin, Not sure if this will be helpful or not, but I have completed a couple of pot height retrofits for these waves and I seemed to remember that one of my clients spilled some solder and shorted out the 24vdc power supply. I am pretty sure this

We have a Delta Max (leaded) and a delta wave (lead free) and a soltec Selective solder. The software that runs the selective solder is much different than that of the wave machines. We have fitted our selective with a leaded and lead free pot to han

The heat you are putting into it is replacing heat it loses. The greater the delta T the greater the heat loss. You lose less heat if the pot is cold. Yes you need to use more heat at the start of the day but it is less than the heat needed to keep i

Hi, Thanks for all the info. Do you have a Nitrogen generator for the selective soldering machine? How does the cost of running that compare to the cost of keeping that big pot in the Delta wave hot? Have you ever experimented with check the costs

Hello all, I have a problem with the wave 6622c . The temperature of solder pot and preaheating zones 1 and 2 is not increasing. the strange thing is that the machine is not display no error. Can you help me with some advices?? regards

We installed a Soltec Delta 3 a few months ago and have been trying to run with a VOC free no clean. We're using SN100C in the pot. We are spraying the material and have top/bottom preheat. Evaporation of the water in the flux is a bit of a stru

Sure. Treat it like wave solder. Top side wetting is generaly harder to achieve than wave so don't over look it. On most selective solder machine, the delta-T is also something to look out for. Most move from preheat to pot. And snce the pot por
