Possibly, that looks a lot like the one I used (handles are identical) 
back in the later 90's but with different tips.  Two problems, the major 
one being that it STILL has a 2 wire line cord, so no static grounding 
and the heater barrels are some sort of metal that isn't conducive to 
making a good electrical ground connection to, and it needs to be run on 
a small powerstat so you can turn the voltage down to the 60-65 range 
otherwise its way the hell and gone too hot 4 or 5 minutes after you 
turn it on, and when doing the caps in a DVC-pro vcr, it will be on for 
at least 6 hours of the working day.  Even then, I found it hot enough 
to cause the pencil eraser sized caps to explode as I was removing them.  
The copper tips are always annealed and very easily bend as you compress 
that spring to bring the tips to a spacing suitable for warming both 
side contacts, and that 20 thousandths of bend puts the tips in full 
contact with the sides of the caps & they pop about like Orville 
Redenbauchers finest.

But as usual, it was the best we had at the time, so when in Rome...
