Don, using an ordinary light dimmer to control any heating device such as 
shank bender, soldering gun, hot air gun and so on can be dangerous.  Most of 
the dimmer switches use resistance to control the output, the same as the 
heating devices use to produce heat.  The combined resistances can easily put 
to much load on the system and a potential for fire.

The wattage controllers work differently and are safe but the technology is 
more expensive so thats why they get the big bucks.
