I placed an order on 9/27/2017. The invoice ID was 1553891
One of the items that I ordered was the Atten 937 Soldering Station. I attempted to use the soldering iron today for the first time. I followed the calibration procedures as defined in the owners manual. I set the temperature control knob to 400 degrees Celsius / 750 degrees Farenheight. I then checked the temperature at the tip using a Raytek MiniTemp Infrared thermometer. According to the Raytek website, the thermometer will read temperatures up to 750 degrees Farenheight. The temperature read much less than 750 degrees Farenheight. I then attempted to calibrate the temperature. Ultimately with the calibration pot rotated clockwise to its upper limit and the temperature control knob to 400 degrees Celsius / 750 degrees Farenheight, the maximum temperature the tip would reach was 250 degrees Farenheight.
Should I try something else or should I return / exchange the device?

Re: Atten 937
As a quick reference check, can you melt solder with the iron at all?

60/40 solder melts at about 370 F. Lead-free alloys are all over 400 F:

Not familiar with the Raytek unit, but most of the IR thermometers will report the average temperature of everything in their field of view. With something as small as a soldering iron tip, the measurement may be skewed by the temperature of whatever is in the background.
Also, the emissivity of a clean iron tip is going to be pretty low, So IR readings will be lower than for a dirty tip at the same temperature. IR temperature sensors need to make some assumptions about the emissivity of what they are measuring.

Re: Atten 937
While the iron will melt thin gauge solder applied directly to the tip when pressed against the leads from an led and a resistor the leads don't get hot enough to get the solder to run. That is true with the temperature set to max.

Re: Atten 937
OK. We can try replacing the unit. Please contact [email protected] with a link to this thread.
