Input:
Question: It says optional water cooler, does it come with it, or do i have to find it? How how thick of metal can i weld with this?
Document: The gas hose seemed flimsy to me, but everything else is super heavy duty. After installing everything, I found the  gas hose was more than adequate to do the job. The torch comes prepared to accept 3/32 electrodes. Beware it does not come with electrodes.I read the included (quick start) guide and was welding within a few minutes.
I dont need to weld cans together but on DC with 5 amps I could do razor blades just for braggin rights .
5/32" rod produced a very good weld puddle and high quality weld.Check out the 200DX stick mode video i did on Youtube.http://www.youtube.com/watch?v=mOGD1ffzFEkThis makes my 3rd Everlast machine all have performed great.
box was in rough shape on arrival. got it all unpacked and was dismayed when it wouldn't strike an arc on tig. I thought "oh no, I should have never purchased a Chinese welder" but called tech support and they suggested I check my input voltage. Being experienced with electrical wiring I knew the machine was busted and it wasn't my wiring. lo and behold the terminal on the receptacle I put in for the welder had come loose on one of the 240v legs. Fixed that and it works great.
I recommend this welder. I've been welding for over 2 decades, this machine is the real deal. It gets the job done and has great power. I use this almost every day to weld up stainless steel roll cages. I also do plenty of aluminum trailer repairs. I have a Miller welder in the shop and this Ever-last does just as well as the blue and the red. i am happy with this machine.
I am however very pleased with my purchace of my Everlast 200 DX Tig , I have been welding for about 22 yrs and used many many machines . I am mostly a mig welder guy , but currently employed as an industrial mechanic in a food processing plant and I fequently tig weld stainless . But I bought the 200 DX for a home project for weldingup a extra hoop on my paramotor frame and cage .
Although I have had just a short time with the system, it has outperformed my older &#8220;Name Brand&#8221; unit. I am a weekend warrior when it comes to welding, you know the type, weld for a bit then move on to a different project.The unit arrived in the original packaging and upon opening the box the main unit was well packaged for transport. The accessories were loosely packaged in a separate box that allowed the items to shift during transport.
The 1st unit I received was defective, with no inverter output. After talking with Everlast tech service and going over setup issues to determine that it was indeed defective it was returned for replacement. I promptly received the replacement unit and it functions correctly. The machine has good weld characteristics, stable arc, good control through foot pedal or trigger switch. Set up for weld parameters is easy, although the amp control is very touchy.
I use to be an iron worker and spent years welding and attended Lincolns welding school. I no longer weld for a living, just do some stuff at the house. For the weekend enthusiast this is a great machine! I could not justify paying $2,000.00 plus for a 200amp ac/dc tig welder, because I may not use it every weekend. I wanted an inverter machine so I could run it off a generator and make some side money.
Note: Upon cover removal I found stainless steel sheet metal screws (holding green cover at bottom) to have slightly stripped-out internal frame anchor - nutplates should be employed. I used 1-size larger SS screws upon reassembly.Two decals on rear of unit caught my eye, an "Inspected By" and a "Tested By". These Decals are not placed there for `show'; they shout Management's effort to meet/exceed pre-established quality and reliability Standards.
