Lotos LT3500 Air Plasma Cutter is a 35 A entry-level plasma cutter designed to meet the variable demands of DIY metal workers and enthusiasts who need their plasma cutter once or twice in a while.
Considering the price and specs, you can’t expect too much. But, Lotos LT3500 rises above the saying “you-get-what-you-pay-for”. It’s a more compact and affordable alternative to Lotos LT5000D Dual Voltage which comes with higher amperage, cut thickness, and duty cycle.
Who Is LT3500 Air Plasma Cutter for?
The ideal group of users is the one that takes the cost of buying a plasma cutter quite seriously. So, LT3500 Plasma Cutter is a wonderful pick for DIY hobbyists and professionals handling small projects.
You definitely need a more advanced and expensive unit for higher cutting capacities and mechanical performance as required by metal fabrication workshops.
Problems You Might Face
Certain questions might come up as you attempt to use this Air plasma machine. Look at the discussion below for the answers.
Understanding the Air PSI-Thickness Ratio
The answer can’t be very straightforward. For some ideas about the ratio, you can try and think about this example. Since the machine’s output is 35 A, you need to set 45-55 PSI for cutting 3/8″ using 110V.
Calculating the Right CFM for an External Air Compressor
Assuming that you want the machine to cut through 1/4″, the psi has to be 70-80 on a consistent basis. Some users have reported to enjoy working with 55 psi having a tank that holds 26 gallons. According to the manufacturer, you should maintain at least 4.0 scfm at 70 PSI.
Understanding ‘Inverter’ and ‘Air’ for This Plasma Cutter
This unit uses ‘Inverter’ as its electrical part which is responsible for allowing the plasma cutting actions to take place. The ‘Air’ blows the metal bring cut away.
Beware of Using Shielding Gas
If it were an oxyacetelene cutter, you would think of using some shielding gas. But for this unit, clean air that is free of any kind of oil or moisture is the only choice for best performance, and that has to be delivered through an external air compressor.
- A highly affordable plasma unit for cutting a variety of materials including copper, steel, and aluminum
- Standard clean-cut and severance thickness for the price
- Pilot arc with HF start for fast and precise cutting quality
- A lightweight unit with easy setup procedure for ultimate portability
- A functional cooling system to ensure the proper utilization of the duty cycle
- No dual voltage system
Lotos LT3500 Review: Features and Benefits
Except the arc system and HF start, the product comes with nothing like advanced technologies. Reasonable cutting capacities, power factor, and moderate efficiency are all you can expect.
Cut Thickness and Capacities
It cuts through three different metal types, such as mild steel, aluminum, and stainless steel. Maximum cut thickness is 2/5 inch and severance thickness is 3/5.
In practice, you may experience some compromise on the thickness measurement unless you aren’t adept at drag cutting or maintaining a steady hand during plasma cutting.
Inverter machines are no longer a surprise these days. When a desirable design such as this one comes at a highly affordable price, anyone may question its efficiency.
As in a top-of-the-line unit, this particular technology has an impact on the design and efficiency of this model. It’s not only lightweight but also draws only as much power as a small electronic appliance does.
Pilot Arc and HF Start
As an essential part of modern plasma systems, pilot arc is known for its ability to allow users to cut clean material without affecting the lifespan of the consumables unnecessarily. You would like an edge in drag cutting, relying on the pilot arc won’t hurt.
If you’re about to work on old metals with a lot of crap on its surface, the arc system makes it easy for you to get rid of the rust, dirt, and unwanted buildups. Having this feature at your disposal means you can save yourself some prep time.
The HF start may not be of much use on most occasions except for cutting aluminum in which case, you’ll benefit from the touch-less method.
Duty Cycle and Cooling System
You’ll have 35% at the full output. Nothing exclusive, you see! Here comes the built-in cooling system which is good enough to ensure that you won’t miss a bit of its duty cycle.
Speaking of a budget plasma cutter, you see that each factor on the list of Lotos LT3500 specs comes with a compromise from those of a more expensive model. Then, why is it still worth your money?
It comes at a price which is the smallest you can expect. Moving forward, you want to check on the functional features, such as cutting thickness, duty cycle, arc system, and design.
Despite being on the entry point of everything, the specifications aren’t useless at all when beginners and hobbyists want to get their hands busy doing light plasma cutting works on occasions. Now that you know when to think about a plasma system such as this one, your buying decision can’t be easier.
