10. Mophorn TIG-200 TIG Welder
- TIG machine or arc welder
- Infinitely adjustable amperage knob
- Amperage range 20 to 200 amps
- Dual input voltage 120/240
- Compensates for power fluctuations
- Simply flip switch for TIG or stick
- 8-foot torch lead
- Only weighs 20 pounds
- Inverter powered
- Lift-type arc starting
- Hand controller only, no foot pedal
- Reports of faulty overheat protection
The Mophorn TIG-200 welder is our Budget TIG welder in this roundup because for the money, there’s a lot to like here. Dual 120/240 dual voltage input power, 60 percent duty cycle and 200 amp power output on a machine in this price range is simply amazing.
It also offers the ability for either TIG or stick welding process, a wide 20 to 200 amp TIG operating range, hot start and an infinitely adjustable analog amperage control.
One significant disadvantage is the lack of a pedal control. The TIG-200 uses a fingertip control instead. Unfortunately, it does not accept any available pedal system, either.
This isn’t a deal-breaker given the price, but just think about it. The TIG process already takes a hand to use the torch and a hand to feed welding rod into the puddle. An added hand control doesn’t make a difficult job any easier. The foot pedal has its place in TIG work.
With that said, users reported smooth welding and many were amazed at the price vs. performance value of this TIG machine.
Our TIG Buying Guide
Whenever you’re shopping for the best TIG welder, the main factors that should determine your choice are:
- What types of projects will you do the most?
- What specific functions do you need?
- What is your budget?
What Types of Projects Are You Planning to Do?
TIG welding is most suitable where bead appearance is important, like in bicycle frames or on truck bumpers, lawn furniture and the like. It also is the most appropriate way to weld very thin sheet metal, because stick and MIG processes put too much heat into the metal and result in burn-through.
Aluminum and stainless steel are the other main places where using a TIG welder is the best way to get the work done, because of its penetration and lack of contaminants in the weld.
What Kinds of Functions are Required for Your Work?
Although it’s possible to weld aluminum with DC current, you will frequently see the rule that you must use AC output to weld aluminum. One reason for this is that AC welding allows the use of high-frequency pulses that keep the weld puddle clean. Another reason is that a primary advantage of TIG welding is heat control, a highly important factor in welding aluminum.
Options to look for in regard to available functions are AC vs DC capability, plasma cutter, ability to select the AC waveform, for example square wave or true sine wave and an adjustable pulse rate.
Multi-Process Machines Offer More Functions for Your Money
A multi-process welder can give you more versatility for the same money. Sometimes they can offer MIG or plasma cutter ability along with TIG.
How Much Can You Spend on Your Machine?
In the end, there are enough functions and technology choices available when buying a TIG to drive welder costs to the same level as building a house.
It’s important to decide what functions and equipment are most important and staying under your final number to find the best TIG welder for the money. Don’t forget to take the length of the warranty into account.
What to look out for
Some equipment is essentially necessary, such as a foot pedal to control heat or a flow meter-type gas regulator.
Does the TIG welder you’re looking at include these items?
Will you need to buy higher-quality pieces to get the real potential out of the welder?
Check The Duty Cycle Rating
Check the duty cycle rating of the welding machines and the output power they’re rated at for that percentage.
Duty cycle is the percentage of 10 minutes in which the welder can operate continuously before overheating.
A 40 percent duty cycle means you can weld for 4 straight minutes at the rated power. That’s actually quite a long time to weld continuously. You will find that the more expensive American machines seem to have much lower duty cycle ratings than the less-expensive Chinese-built welders even though they cost more.
Remember the old adage about something seeming too good to be true.
This has to do with ratings methodology and the fact that the expensive big-name companies are more cautious because their equipment is used by professionals on long shifts over years in tough environments.
Don’t forget to budget in gas cylinders, the cost to fill them and optional but important parts like water cooling.
This is the Big Leagues
TIG welding is a big step up from basic welding skills, and TIG machines cost a lot more than other welders, offering obscure features not found on other machines. Educate yourself at welding forums and manufacturer’s websites on what terms and functions mean before spending your money on something you don’t even need.
With those factors taken into account, we believe the Miller MaxStar STR is the best TIG welder as it offers the most bang for the buck and it is designed for professionals in mind. Features like memory card storage, wireless remote control, Miller’s legendary customer service and the lengthy warranty are some of the big reasons why we selected the MaxStar as our Pro Choice in this guide.
If you are not a professional, then both the YesWelder TIG-250P and the Eastwood TIG200 offer AC/DC TIG, stick welding, a nice selection of features, quality and power at affordable pricing. Both include foot pedals and a wide range of settings as well.
The YesWelder TIG-250P is almost entirely digital, so if that’s something that bothers you, the Eastwood TIG200 features a wide range of analog settings. The YesWelder’s main advantage over the Eastwood TIG200 is that it’s generator-friendly with its tolerance for power fluctuations.
The PrimeWeld TIG225X is also worth a look with great customer service in a similar price range.
