Query: Love my 140watt Weller soldering gun, this one only 150watt

Got this as a higher power compliment to my 100/140 watt Weller soldering gun. Keep in mind that this is the gun only, in a cardboard box, no case or accessories, which was fine with me. It is new. Didn't seem much more powerful in use. Checked it with a watt meter and it only drew 125/150 watts. Yes, I know the first click is high, and fully pulling the trigger is low. Cleaned and tightened the tip, no improvement. On the good side, the return process was great. This was my first Amazon return. Print the label, box it up (in the box it came in), take it to the UPS store, they put the label in a clear plastic shipping label thing, slap it on the box, done. Practically easier than taking it back to Home Depot.
