TROUBLE SHOOTING:
Soldering Gun doesn’t heat properly:
If your Weller
® Soldering Gun appears to be heating, but not hot enough to
perform the job, try loosening and re-tightening the tip. It may become
necessary to clean the connecting area of the tip ends with sandpaper or
possibly install a new tip. (Refer to Replacing Tips section). A good
electrical connection between the tip and the soldering gun is essential for the
tool to heat properly.
Light bulbs don’t light up:
Try tightening the bulbs in the sockets. If problem still persists, then
replacement bulbs can be purchased. (Part # 7333).
