Question: hello good afternoon,  If i buy the used one, for how many years the warranty is?
Document: These small head torches with their super flexible cables are a pleasure to work with, particularly in confined spaces. Once you try them, there is no going back.I have used this unit regularly for over 6 months and it continues to impress me with its reliable solid performance and good value. It has allowed me to significantly improve my welding skills without experiencing any buyer's remorse or regrets that I should have gone for a better unit with more features or power.
And the hose coming out of the torch power cable connector is the hot water return. This hose was not long enough to reach the cooling unit and had to be replaced with a longer one.
***Update,  Everlast has contacted me about this review and offered to set up a time on a Saturday to help me determine if I have a defective unit. That kind of impressed me as I'm always stuck in the office during the week. I'll be updating this review based on the results of my experience. ***Well, i purchased one of these about 5 months ago. I did not purchase from amazon because they didn't sell the 2013 model.
After looking at several brands and reading reviews from the internet, I purchased the Everlast PowerTig 250EX. It has more than met my expectations. From welding very thin aluminum or stainless or heavy hot rolled steel, this machine handles them all with ease. Best of all, the price makes it easy to convince yourself to bite the bullet and buy a new welder.
Anyone concerned about buying an import TIG welder, really should consider this unit. I doubt that you could find better bang for the buck anywhere else, and the company definitely stands behind their products. For an inverter welder, it's a bit on the heavy side, but considering the fact that it's 250A as well as an extremely high duty cycle compared to other welders in its class, that is a pretty easy feature to get along with. I've used mine for over a year with absolutely no problems and excellent results.
Bought mine directly from Everlast -  a heavy, well built product that has a lot of options and capabilities. I'm very pleased with the product and the support from the company. Join the Everlast forum and you'll be completely in touch with a good group of guys using these products as well as company moderators.
for the price of upgrading everything that came with this welder to where it needs to be, you can have a real miller, lincoln, etc with real features and support. If everlast doesn't step up on this machine in the next month, I will be getting rid of it and picking up a miller dynasty like i should have in the first place. Money was never an issue. I wanted knobs and not buttons and menus. What I had read about everlast made me think they made good welders.
Just a hobby type shop and not a commercial welder I find this to be a perfect machine. Does everything I need to do and then some. My only complaint would be the fan is very loud. When combined with the torch cooler fan, it is deafening in my little shop.Machine performs very well, and back up support is extremely good. I've written the company on a couple problems and have gotten phone calls back from the company. Great people to talk with and work with.
It has a relatively low profile and offers a smooth, broad range of adjustment, up to whatever maximum you set with the panel adjustment knob.As for the upgraded torch, it is a water cooled WP-18 style torch, similar to the stock torch and a bit too big and bulky for the majority of my needs, however the cables are very flexible which makes positioning the torch effortless.Overall build quality of the main welding unit is very good.
The label on the control panel was wrinkled up and coming off around the screws. For consumables, i received two 3/32" collets and two tiny cups and the basic fittings for the horribly rigid torch and nothing else (not sure where they get premium or $50 value there). The biggest lie was that this machine was in fact only 250 amp. I called with a complaint about each of my issues and was treated like an idiot.
Answer: no
