Very clean, fully functional, great design and comfort grip. The Junior Weller 8100 soldering gun looks like a toy but performs well at 1.1 AMPS, 120 Volts, 60 cycles. The large Weller D550 works at 260/200 Watts, 2.5 Amps, 120 Volts, 60 cycles. Both of these vintage soldering guns are easy to open (3 screws). Allows easy maintenance.
