One of the most useful items in your shop is the mig spool gun: This is a mig wire feeder and mig gun in your hand! With this gun you can easily weld, aluminum, stainless steel, carbon steel, aluminum bronze, silicone bronze, or any filler metal on a 4" spool. If you have a special application you can always spool a small amount of wire for a special job.
The AEC-200-DM is unique in the welding industry. This gun is designed to be directly installed on any constant potential (Mig) power supply. The "DM" has the drive motor, motor speed control pot, motor speed control module, and gas valve in the gun! All you have to do is supply it 24 volts (AC) and it returns a 24 volt signal to the power supply to energize the contactor! Very, very simple and easy for the end user to maintain!
