    1st Tig Welder and its awesome

    Some things you just have to go with American made. I looked at the Imports for a long time before going with this one. I purchased a Lincoln Mig 175 15 years ago and it was flooded in Hurricane Katrina. Lincoln repaired the circuit board for nothing and the welder is still going today. Given the quality of this machine - I'm sure it will last just as long. You know its built well just by looking at the connections. Everywhere it counts - Its metal and not plastic. The Flex-head that comes standard is a real bonus, and the Amp-control - foot pedal is awesome. I purchased the refurbished unit to save a few hundred, but it still has the same warrantee and I know Lincoln will stand behind it and then some. So far I have about 6 hours weld time doing both tig and stick and have had "ZERO" issues. One more thing - the dual voltage is a really nice feature and it comes with the plug for each 110, and 220. Great job Lincoln, and a great value!

  • Most critical review

    finally able to use it today, and it won't start up.

    I'm very disappointed in this machine. I was finally able to get it set up and use it for 1st time today (5/3/18) and all it does is flash. I can't adjust anything on it. I can't change settings, mode, nothing. I used Lincoln in my welding classes so I was expecting to fire it up and get to work, but nope.

  • Good product, good quality, lightweight with great features

    I don't use it already at home because i had to change electric wall socket to use 20 A plug.

  • Lincoln Square Wave TIG 200

    The welder looked brand new out of the box as did all included accessories. It worked exactly as I expected and needed. DC TIG function was easy to setup and functioned perfectly with 12,14 &16 gauge square stock and 1/8th inch mild steel plate materials, using 3/32, 2% Ceriated Tungsten. I used a 230 volt power source and had no duty cycle issues @ 100 Amps. A quick tap on the pedal out of arc range starts gas purge/pre-flow. Apparently gas post flow is regulated by factory presets although I couldn't find any info in the manual addressing pre and post gas flow. Experimented a bit with the pulse settings but personally find the arc flutter distracting. I have not used the machine in Stick and AC TIG modes or tried the machine with 110 volt power source but expect to at some time. I do not plan to use this machine daily in commercial or heavy duty welding so I can not address those points. In my opinion it is a great machine for the price and my purposes.

  • needs one more setting:

    A little disappointed that it doesn't have a setting for post gas duration. Wastes a lot of argon, but I made my own system to shut down the gas. Other than that, good machine

  • Small shop perfect!

    I have a small repair shop this machine is perfect for the work I do. The versatility of this welder is outstanding. It gives you the ability to repair weld anything, from cast iron to cast aluminium.

  • Great welder, but

    I love this welder. It all came in great condition except the foot controller came broken. I had to re solder a bunch of connections in the cable to get it to work.
