1. The Invertig-160 DC is small in size but big in output. Since it can operate on either 110 or 220 volts it is a perfect setup for home use or to take from job to job. The power cord is 15 feet long and needs an end cap depending on your setup (you pick the power outlet 20-30 amp). The foot pedal and the torch each come with 25 foot long leads. Also the Invertig-160 DC comes with the Flowmeter with a 6-foot hose for the shield gas (Argon). Also you can get the starter kit that includes Tungsten, collets, collet bodies and alumina cups for the torch in four different sizes for around $50.
