Auto-Set™ A breakthrough control that automatically sets your welder to the proper parameters. Auto-Set offers all-in-one MIG minus the guesswork! Simply set the wire diameter, set the material thickness and start welding!	Smooth-Start™ This technology provides a smooth, spatter-free start. The best starting machine in the small MIG category! No more pop-gun starts or spatter to clean up.
Manual Mode Gives you the flexibility to manually set the machine when welding aluminum, stainless steel or anytime you want to set your own parameters on mild steel.	Durable Cast Aluminum Drive System Incorporates dual groove quick-change drive roll and spring-loaded tension arm with calibrated tension knob, all designed to make setup easier and faster.
Thermal Overload Protection Shuts down the unit and activates over-termperature light if airflow is blocked or duty cycle is exceeded. Automatically resets when fault is corrected and unit cools.	"Tip Saver" Short Circuit Protection Shuts down output when tip is shorted to the work. Extends contact tip life and protects internal components from damage. Trigger reset permits quick reset at torch rather than unit
Standard Built-In Solid-State Contactor Circuit Makes wire electrically "cold" until trigger is pulled. This makes the unit safer and torch easier to position before starting to weld.	Easy Access to Output Studs Provides convenient polarity changeover when switching from solid or flux cored wires

Rated 3 out of 5 by Parttimer Poor communication I purchased this product online on a Sunday afternoon. after 3 days I had received no communication about my order. I did not know if it went through was rejected or whatever, absolutely no after the online purchase communication. I finally called and they said it was a good order and would ship shortly. The product was exactly what I expected but expected a lot better customer service buying factory direct and paid a premium purchase price for that option without the better service April 1, 2013
