Easy-to-Understand Operator Interface.
It's as easy as "1, 2, 3" to set your machine and start welding! 1. Power-up2. Select material type3. Set material thickness range
Utilizes Latest Inverter Technology
By utilizing an inverter-based AC/DC power source, a more efficient (less energy is used) and consistent welding arc are provided compared to older transformer based TIG machines.
Whether it's in the shop, garage or at the race track, at 50 lbs it can be taken anywhere.
Dependable Arc Starts
Provides HF, non-contact arc starting to eliminate tungsten and material contamination time after time.
Reduce Noise, Maintenance and Operating Costs.
Our Fan-On-Demand™ cooling system only operates when needed. This cuts down on fan noise and reduces power consumption and contaminants drawn into the machine.
Eliminate Waste of Expensive Shielding Gas
Our Auto-Postflow feature optimizes postflow time based on welding amperage. This allows for proper shielding of both the weld end zone and electrode every time without waste of gas or need for adjustment.
Fully Adjustable Amperage Setting
The full amperage range is available from 10-165 amps on both DC and AC output.
Torch Designed for Maximum Operator Comfort
The package comes standard with a Diversion Series foot control and Weldcraft WP-17 TIG torch. This 150 amp, air-cooled torch features a compact and durable design ideal for both the professional and hobbyist welder.  The Diamond Grip head design has ergonomic contact points for thumb and fingers, provides a more comfortable grip, and reduces operator fatigue.

Reviews & Ratings

Rated 1 out of 5 by from Only lasted 7 1/2 years... I bought this TIG welder as my first TIG machine in March of 2009. I thought I was buying a quality machine, from Miller's name and reputation. 2 weeks ago it stopped working and it started showing the "low voltage input" error code from the troubleshooting guide. I took it to the closest Miller authorized service... after 2 days... I got the call... the call like a girlfriend was breaking up with you... even worse... like she was breaking up with you by a text message. Over $1000 to fix the machine, the man said on the other side of the phone. My heart sank. I thought to myself, "Miller, Miller, why have you forsaken me?!" I told the man, of bad news, that I would think about it and call them back. As I sit in my own dark hold of Miller depression, I ponder if I should just let this Miller go to the welder graveyard. Based on the inner accountant in me, this machine has cost me $179 per year. Could I just buy the main board myself and replace it, saving 300 bones? What to do?

Rated 1 out of 5 by from Junk! I have had nothing but trouble with my welder! Over the last year I go to start the arc and all I get is a quick "spark" and nothing. At one time I was able to turn off the welder and back on and I would get my arc, but now NOTHING!!!...Going back to Lincoln!!!!!

Rated 4 out of 5 by from Great for light DC. Needs AC balance. The machine really shines welding stainless motorcycle exhausts. Also good for mild steel, but why not use mig. I've had the machine for 5 years with no problems. I bought it before the 180 came out so I would have bought that instead. I want to get AC balance and freq adjustment for welding dirty castings, so I'll be selling this.

Rated 3 out of 5 by from AC failed Purchased the unit a few years ago and used DC several times with great success. Just tried the AC and all I got was the high frequency starting arc, no power arc. I was able to tough start the power arc. I of course checked the warrenty period and I am a few month past the deadline. This is the first time I tried the AC - My Bad! Robert

Rated 5 out of 5 by from nice machine I would recommend this welder for any body that makes motor cycle or car parts. I mostly make stainless steel parts, but once in a while i weld aluminum and it is nice to be able to weld aluminum with the same machine. One thing i would recommend is to buy the foot control, i find this much easier to use then the finger control on the torch.
