• Very affordable for a 200-amp welder
• Quality arc performance
• Good duty cycle rating
• Lots of built-in features

Cons:

• No high frequency start
• Foot pedal not included
• Argon regulator could be better quality

Primeweld TIG225X

With a max amperage of 225, the Primeweld TIG225X offers ample power for welding projects. It’s also packed with advanced features. Key details include:

Pros:

• Powerful 225-amp maximum output
• Excellent arc stability
• High frequency start capability
• Foot pedal included

Cons:

• More expensive than lower-amp models

• Argon regulator could be higher quality

Comparison

When comparing the top affordable TIG welders, the Amico TIG-160DC stands out for its balance of value, performance and features. It provides a max output of 160 amps, which is ample for most hobbyists and home garage use. The arc is smooth and stable. And it includes handy controls like AC balance and pulse welding.

For more power, the Lotos TIG200ACDC bumps up the max amperage to 200 amps. This extra capacity does come with a higher price tag. But it still represents a great value TIG welder with advanced features.

The Primeweld TIG225X is the most powerful of the three, with 225 amps maximum. It’s the best choice for welding thicker materials. But the higher price makes it less “cheap” than the others.

Overall, the Amico TIG-160DC hits the sweet spot of price versus performance. For most hobbyists, its 160-amp output will handle a wide range of materials, all while coming in at a very wallet-friendly price point.

Frequently Asked Questions

What thickness of metal can an entry-level TIG welder handle?

An entry-level TIG welder with around 160 amps of output, like the Amico TIG-160DC, can typically weld metals up to around 3/16 inches thick. For thinner gauges from 24 gauge up to 1/4 inch, it will perform very well.

What are the benefits of an AC/DC TIG welder?

An AC/DC TIG welder allows you to weld a wider variety of metals. The AC mode provides the cleaning action needed for aluminum. While DC mode works on steel, stainless steel and other alloys.

Is pulse TIG welding better than standard TIG?

Pulse TIG welding can offer benefits like easier arc starting, good puddle control, and reduced heat input. This makes it preferable for welding thinner materials. But for many applications, standard TIG welding works very well.

Can I plug a TIG welder into a 110V outlet?

Some TIG welders run on both 110V and 220V power. However, 110V will limit the maximum amperage. For example, the Amico TIG-160DC can output 160A on 220V, but only 130A on 110V.

Is argon gas required for TIG welding?

Yes, to TIG weld you need an argon tank and regulator. Pure argon shielding gas is used rather than argon mixes like C25 or C50. Argon provides optimal arc stability and corrosion resistance.

Conclusion

Finding a high-quality, affordable TIG welder comes down to carefully comparing specifications, features and value. The welders profiled here offer the capabilities and reliability hobbyists need, all while fitting within a budget. For most, the versatile Amico TIG-160DC hits that sweet spot. But the Lotos and Primeweld models also present excellent options. The right welder comes down to matching its amperage range, features and price to your specific needs and wallet.
