Duty Cycle

The Rated Duty Cycle refers to the amount of welding that can be done within an amount of time. The Eastwood TIG 200 has a duty cycle of 60% at 190 Amps. It is easiest to look at your welding time in blocks of 10 Minutes and the Duty Cycle being a percentage of that 10 Minutes. If welding at 190 Amps with a 60% Duty Cycle, within a 10 Minute block of time you can weld for 6 Minutes with 4 Minutes of cooling for the welder. To increase the Duty Cycle you can turn down the Amperage Output control. Going above 190 Amps will yield a lower duty cycle.

What is TIG Welding?

The Tungsten Inert Gas (TIG) process is the most effective way to weld thin ferrous metals (steel, stainless steel, iron, etc.) as well as non-ferrous metals (e.g. aluminum, copper, nickel). We’ve developed affordable TIG welding machines that are powerful, easy-to-use and portable. Our TIG Welder Guide will help new and experienced fabricators select the right welder.

What to Look for in a TIG Welder

• Best TIG Welder for Beginners: A multi-Process machine like the Eastwood Elite MP140i is a multi-process welder that does TIG welding on steel up to 3/16-inch thick (or ¼-inch with the optional spool gun). Plus it allows you to MIG and Stick weld, making it a very versatile unit. Multi-Process, or MP machines, are also available in other, larger sizes for welding thicker metals.

• Intermediate TIG Welding: For more experienced bodyworkers, the Eastwood TIG 200 DC is perfect for welding steel and stainless up to ¼-inch thick. If you also need to weld aluminum, check out the TIG 200 AC/DC welder. For reference a DCmachine welds steel and stainless while an AC/DC machine not only welds steel and stainless but also aluminum.

• Advanced TIG Welding: Are you a skilled TIGwelder who needs as many controls and features as possible for the best performance? Then check out the TIG200 AC/DC Digital Welder that offers Pulse, 2T/4T Modes, AC Frequency Control and programmable settings.

Eastwood provides a 3-year manufacturer’s warranty and lifetime tech support for all of our DIY welders. Browse the Tech Library or Eastwood Garage for expert tips about TIG welding and what to look for in your equipment. We’ve been an automotive restoration and customization leader since 1978.

Application Tips

Best AC/DC TIG Welder

A 200-amp Eastwood TIG welder is the most affordable way for mechanics and other metal workers to get excellent welds on all of their projects. This AC/DC TIG welder uses a tungsten electrode to heat metals and joins them together without becoming part of the finished weld, reducing splatter and mess. The AC mode is used for aluminum, while the DC mode can be used to weld steel and stainless steel in tube, sheet or bar stock form, offering incredible versatility in a skilled set of hands. A stick-weld feature is available as well for use in outdoor conditions or on dirty metals.

Our team has designed this machine to be easy for beginners to use while still offering the capabilities that advanced welders need. It has a straightforward control panel for setting your arc, amperage and mode. The AC/DC adapter cord makes it a cinch to switch between modes. Our portable TIG welders weigh just 45 pounds so you can load them into a car, truck or trailer and bring them wherever you're needed.

Eastwood Tig 200 ACDC Welder

A Complete TIG Welding Package

Anyone with a power source of 110 to 240 volts can power the Eastwood TIG200 Welder for spot welding or fabrication on metals thick and thin. You'll get precise welds thanks to the high-frequency instant start and square-wave AC inverter that assist with control and accuracy. It is rated for a duty cycle of 60 percent at normal amperage, meaning you can weld until the job is finished.

Everything is included with this welder for doing excellent welding straight out of the box. In addition to the AC/DC TIG welder, you'll receive a shielding gas regulator and hose (gas tanks sold separately), a Flex Head WP-17 Series TIG torch that uses industry-standard consumables, several sizes of gas nozzles and collets, two tungsten rods, a gas flow meter, rocker style foot pedal for improved precision and much more. Eastwood backs each welder with a 3-year warranty and our 100 percent customer satisfaction guarantee.

Eastwood TIG 200 ACDC Welder

Eastwood 200-Amp TIG AC/DC Welder

Advanced DIY fabricators and professional body shop technicians can count on the TIG 200 for their automotive restoration work. These AC/DC welders do precise, clean welds on mild steel and stainless up to ¼-inch thick. Use our TIG welders for aluminum thanks to the square-wave inverter or switch to the stick welding mode for additional versatility. The 120V/240V adapter cord makes it easy to switch between AC and DC power supplies.

From aluminum sheets and steel tubes to bar stock, the Eastwood TIG 200 will Do the Job Right. Each portable AC/DC TIG welder has a long WP-17-type torch, gas lens kit, rocker-style foot pedal and ground cables to navigate any project. Fine-tune settings on the control panels so you get the best results. We offer a three-year manufacturer's warranty and 100% customer satisfaction guarantee.

Rated 5 out of 5 by from Definitely buy This machine is a great little welder. I spent 2 hours straight running test welds on every thickness and at varied amperages; I am fully impressed! I ordered the machine on Tuesday and was welding Friday night. It also came with one Red and one Green Tungsten. The foot pedal is comfortable and seems durable. I ran it both on 110v and 220v with no change in weld quality.

Rated 5 out of 5 by from Eastwood take 200 I had a Miller diversion 180. Got rid of it because it looked like it was going to be a boat anchor soon. This Eastwood TIG 200 in my books is a better machine. I am just a hobbyist, but so far I like this machine better than the Miller.

Rated 5 out of 5 by from A 1 customer service! I ordered the welder after burning up 2 yes welders in a row. Arrived before scheduled and was packaged beautifully. After using welder for 1 hr it tripped the overload and would not come out. Called customer service no questions asked they immediately sent a return label and a new machine within 3 days. Customer service is excellent. New machine works flawlessly so far.

Rated 5 out of 5 by from First TIG machine I just got it and started playing with it. Between watching all the videos I can and the help of a couple of friends, I am teaching myself how to use it. It is my first TIG welder and my comparison is, fairly or not, to my Lincoln MIG machine......Overall, it seems cheaper made than the Lincoln...maybe the TIG doesn't need to be "heavy duty" and by that I mean thickness of the steel casing. SO far it performs as advertised and I am very pleased with it. It was easy to assemble, and everything was in the box as advertised. I would recommend it, again based on my limited use and experience TIG welding.

Rated 5 out of 5 by from Tig 200 AC/DC I am new to tig welding. I had bought the Eastwood MiG 175 in 2019 and enjoyed the product so when I decided to get into tig welding I came back to Eastwood. Their product is built well and priced right for the consumer.

Rated 5 out of 5 by from Love this welder I have been running the TIG200 for about 2 years now. It does everything pretty well. I’m not an expert tig welder but it didn’t take long before I was producing quality welds in steel and aluminum. The only criticism I have is the crappy argon regulator Eastwood included with the rig. It’s terrible. I knew it wasn’t stable from day one but I didn’t realize how much it was affecting my weld quality till it failed completely and I replaced it with a new pro star regulator. I use far less gas and the flow is always stable. Don’t waste your time with the included regulator, buy a good one.

Date published: 2023-02-08
Rated 5 out of 5 by from Professional quality at a hobby price! Im still in the learning stages of tig welding but so far this unit has been awesome! Surprisingly the aluminum welding appears to be far easier to adapt to than steel but never the less we are melting metal with a smile in both cases.

Questions & Answers

I found today that the new upgraded tig 200 has been upgraded with the socket for stick welding which i was adding to my welder. Id appreciate if you can tell me if there is something else to modify besides installing the socket to invert polarity.

Asked by: PZD1
You can swap the ground lead and stick electrode holder to reverse polarity, the connectors are the same..

Is the tig 200 able to run from generator power?

Asked by: exampleMan
This unit can be run off of a generator without issues. A Transformer based generator or a Inverter based generator can be used. For peak amperage, we recommend a 12,000W generator.

? Im new to welding just wondering if I can tig titanium with the ac/dc tig 200 or  the tig lcd or what would you recommend.  I would love to weld chrome moly,stainless steel ,and aluminum please help  Thank you 

Asked by: Juice
Do you TIG titanium with AC or DC? Use Direct current. Titanium is usually welded with direct current (DC) and not alternating current (AC), so this limits the range of usable tungsten electrodes to DC-compatible ones. Eastwood 200 Amp AC/DC TIG Welder for Steel and Aluminum ... and worka with thinner gauge metals, especially aluminum or chrome-moly steel.
