High frequency, no-touch arc starting is great for welding or cutting rusty or painted steel.
The 50 amps of plasma cutting juice will go right through 1/2-inch steel. The TIG and plasma torches both have 13-foot connections for a lot of working room. Unfortunately, this machine doesn’t include a TIG pedal but can connect one. Some users complain of quality problems and aren’t happy with the customer service, but these are not consistent problems. There are enough of them to raise an eyebrow, but not enough to be a deal-killer given the 1-year warranty.
The Lotos LTPDC2000D comes with a built-in regulator and offers pulse width modulation, allowing the width of the TIG bead to be set, affecting quality control and appearance of the final product.
8. Lincoln Electric LE31MP Multi Process Welder
- MIG, Flux-cored, Stick, DC TIG
- 30-140 amp welding range
- 120 volt input power

- Mexico made, not Buy USA certified
This is one very impressive multi-process welding machine. The Lincoln LE31MP features a solid aluminum, adjustable gear driven wire feed that can fit either 1-pound or 10-pound spools of wire. It has an internal gas solenoid that will regulate gas when you pull the trigger for TIG use. For MIG gas, the LE31MP multi-process welder comes with an external regulator.
There’s almost no downside to this versatile machine, which offers gas MIG, DC TIG, stick arc and flux core welding. One downside is that to use the LE31MP’s highly-praised TIG process, you need to buy a TIG torch and heat control pedal separately. Another is that even with high build quality, it’s made in Mexico and can’t meet the Buy American standard required by some government contracts.
Users love the welding quality and the construction of this machine, praising every process it runs. It’s able to run from 30-140 amps output power, enough range to go from 24 gauge sheet metal straight to 3/16-inch thick plates. Lincoln backs the LE31MP with a 3-year warranty.
Reasons why multi-process welders make sense:
1. Labor savings from multiple processes immediately available.
2. Space savings by combining multiple machines.
3. Cost less than purchasing several single purpose machines.
Multi-process welding machines make the most sense for small fab outfits, auto body specialists and home DIY craftsmen.
One-man operations can save a lot with one main and one backup machine that still cost less than a whole set of specialized machines.
Which Functions Do You Need?
There is no single standard that determines which welding processes are included. Some only have MIG and stick processes, others have several like TIG, flux core and MIG and still others will add a plasma cutter.
TIG is the best process for sheet metal, hands down. MIG and flux core can both perform well with sheet metal, but only when the arc is easily controlled and the minimum output is below 20 amps. Many sheet metal professionals prefer TIG welders that get below 5 amps.
If you intend to weld thick steel plate, stick arc and MIG processes get the best penetration. Plasma cutters are extremely useful to fabricators. It really saves money on labor when you only have to flip a couple of switches and connect a torch to cut metal right where you’re working.
Saving that walk across the shop to pull a cut adds up to quite a bit of saving over two separate machines.
What’s the Main Process?
The nature of welding technology is that any welding power source can run just about any process. The difference with high-end machines offering every process and multiple settings when compared to cheaper machines with two processes and basic settings is simple. One costs more.
You should decide which welding processes carry the highest priority. Each manufacturer will emphasize a primary welding mode to keep costs down. Be sure the primary function of a given machine is in line with your priorities.
Do you need to do heavy-duty welding, cut quickly and keep moving? You need a MIG or arc welder with a plasma cutter.
If you’re not cutting on a frequent basis, it might be more cost-effective to buy a plasma cutter separately and get a multi-process machine with MIG, TIG and stick.
What Kind of Work Are You Doing?
If you want to TIG weld aluminum, you need a machine with AC TIG welding. The best looking welds on aluminum with the greatest strength are from AC TIG machines.
If you’re going to do a lot of outdoor work, you need to put a priority on flux core or stick arc processes.
Accessories and Options
If you don’t already have the proper TIG or MIG torch, or if you need a heat control pedal for a TIG machine, these should be taken into account when comparing prices. Some machines have features like lift-type arc starts or high-frequency no-touch arc starting for plasma or TIG electrodes. These features actually help to save money by reducing the rate at which consumables wear out. You may find you don’t need dual voltage input and get by with 120 volts input power.
