After seeing a neighbor pick up a small thermal arc unit, I got on the web to see what was available. Keep in mind the only TIG unit I have used is a 1960's water cooled 400 amp Lincoln.
The price and reviews is what brought me to Everlast and with a few $100 Amazon gift cards, my order was placed for the 185. I very much appreciated the ability to weld using 110 volts as well as the ability to use 220 as well. After spending about 3 days watching endless youtube videos and forums, the unit showed up. A bit a time was spent hooking up the 185 and as I hit the HF button....nothing happened. I figured it was user error, but after reading the forums I checked the HF gap....and there was none. I adjusted it to .035 and still no spark. An email was sent to Everlast on Sunday and to my surprise, I had Responses from Oleg, Mark and Katay and possibly one other. The unit was sent back to Amazon and another arrived 3 days latter. Mark sent out a gas lens kit as a kind gesture and is very much appreciated. As Murphy's law would have it, the Argon pressure valve did not work, but they sent another one out asap after a few emails. The new one works fine.
I love the AC ability with this unit and the learning curve with aluminum was made quite easily by watching the countless youtube videos. Once the frequency and balance is set correct, the beads turn out great. Still trying to master the inside 90 degree welds, but am learning to adjust the frequency to spread the heat evenly.

All in all this is a great unit, and customer service could not be any better. I give five out of five stars on Everlast's rating, for product and customer service. Thank you.
