Reviews & Ratings

Rated 1 out of 5 by from On 5th Whip in under 2 years I have had this for under 2 years. Machine works well but the torch REALLY sUCKS! I'm on my 5th torch! If you use it every day the wires in the torch whip short out. I've spent more on whips than I've paid for the machine. It does cut extremely well... when it works. The 3 year warranty only covers the machine so beware.

Rated 5 out of 5 by from performs perfectly, exactly as described and represented Manuals are tops and online info is what sold the unit. We needed something that would cut 1" stock and this really performs. Its clean and easy to use. The value is superior to competitors of similar specs, so the choice to purchase was made for us. The reliability of other miller products we use also helped in the decision.

Rated 5 out of 5 by from Another great product from Miller I've owned a Thermal Dynamic, a Hypertherm and now the Miller 875. Each one newer and more updated version than the previous so a direct comparison wouldn't be fair. However, the Miller is my favorite of the three. It's a higher output machine than the previous machines, it runs great and Miller is a top notch company to work with.
