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   We've also added a digital display so you know exactly what your settings are.
Use It On 120 Or 240 Volt Input Power
Miller's Multi Voltage Plug (MVP™) allows you to connect to common 120 or 240 V power receptacles without the use of any tools. Simply chose the plug that fits the receptacle and connect it to the power cord.
Utilizes Latest Inverter Technology
By utilizing an inverter-based AC/DC power source, a more efficient (less energy is used) and consistent welding arc is provided compared to older transformer based TIG machines.
Torch Designed for Maximum Operator Comfort
The package comes standard with a Diversion Series foot control and the Weldcraft A-150 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.
Light Weight = Portability
Whether it's in the shop, garage or at the race track, at only 50 lbs it can be taken anywhere. You can't do that with those heavy transformer machines!
Reduce Noise, Maintenance and Operating Costs.
Our Fan-On-Demand™ cooling system only operates when needed. This cuts down on fan noise, along with reducing 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.
Dependable Arc Starts
Provides HF, non-contact arc starting to eliminate tungsten and material contamination time after time.

Not Included

  • Argon shielding gas
  • Filler rod
  • Personal safety products (helmet, gloves)
  • Your local welding distributor can provide shielding gas, filler rod and a full product offering.

Reviews & Ratings

Rated 1 out of 5 by from Don't buy unless you can replace the main board I bought this welder 180 Tig 5 years ago and have since replaced the main board. The first one quite working so we bought a new board. This second board fried the 4 IGBT Transistors. Were in the process of replacing these transistors. We also replaced the foot pedal. I sent an email about this welder to Miller and no reply from the company. Gee, what a great company. Can't even reply to a customers email. These main boards cost any where from $1000 to $1600 Can. We probably have used this welder a total of a maximum of 12 hours if that over the five year period. It Cost around $2500 to purchase and now on the second main board which now needs repair. I have never bought a product that has been this problematic. On a positive note we have the Millermatic 175 mig welder that has been fine and has worked flawless over the last 6 years..

Rated 2 out of 5 by from Welds nice, when it works It is a nice machine as long as you realize it has a 10% duty cycle and if pushed it will pop the main board, bingo 1000.00 replacement, and boards are only warrentied for 6 months. I used the machine for 30-40 amp stainless sheet and it poped 2 boards in 4 years, so for whats its worth that's the story on the 180's. My advise, stay away from inverter machines, my other (old school)miller stuff has never given me any issues.

Rated 1 out of 5 by from failure I purchased this product used from someone who was upgrading. After getting it home and set up I attempted to lay my first bead. Within the first inch the machine made a loud pop and died. I checked everything I could and later took it to a local miller authorized repair facility. After two days the verdict is that the circuit card is fried and possibly other parts. How or why they can't say but the replacement part is over $1000 plus labor. After doing some research online I have found a few forums with people talking about the same problem. I could only find one site selling this part and the price is close to the same. I have two older miller products and have had no problems with them but this one, I think its a 2014 model, and its failure and the fact that others have had similar problems I will be reevaluating my future purchases of miller products. I think a $2000 name brand machine should last longer than three years especially when lightly used for hobby welding. I bought this to practice and learn tig welding with hopes of upgrading in the future when finances allowed. Now I am left with two choices, save more money to cover the repair and hope the same won't happen again or cut my losses and save for a machine from another manufacturer. If anyone needs a pretty blue paperweight for parts let me know.

Rated 5 out of 5 by from Taught myself TiG Had my Diversion 180 a year now and like it a lot for small/medium sculptures in steel. It eliminates much grinding that was needed with MiG. Knew no TiG at the start, but read a bit, took a morning of instruction, and then began practicing. Love the (foot pedal) control of TiG and also, ability to do autogenous welds.

Rated 5 out of 5 by from Perfect Machine for the Job! I bought this machine to repair leather cutting dies for two local manufacturing plants. The dies are thicker on the backside and taper to a sharp edge on the front. The "180" performs perfectly and the foot pedal gives me complete arc control. I own three Miller welding products and needless to say I'm a very satisfied customer.

Rated 5 out of 5 by from everything I had hoped for Having no experience with tig welding I bought this particular model based on the recommendation of my local Miller dealer , they even sent out a VERY experienced Tig welding guy to get us started which was priceless. I could'nt be more satisfied with this purchase, the welder does everything we hoped it would do. Thanks, Miller

Rated 4 out of 5 by from Great welder at a reasonable price I recently purchased the miller diversion 180 for some mild fabrication work. The machine is well built and easy to use especially for the beginner welder. It welds both steel and aluminum with ease and the transition is push button. In my opinion the only downfall is not having detachable leads. With that said the leads are very durable and I have not had a problem packing it up going mobile with it. Another amazing feature is the 110/220v power converter. All in all great machine.
