- Welds 32 gauge sheet up to 1/4-inch plate
- Infinitely adjustable controls
- Generator friendly
- Standard Tweco-style MIG gun
- Doesn't come with a gas regulator
- Needs additional parts for TIG
The Forney Easy Weld 140 is a high-quality multi-process MIG, flux core, DC stick and DC TIG welding machine. Because it uses 120 volt input power, it’s convenient to use just about anyplace that has household current available. This machine has an all-aluminum wire feed drive that holds both 2 pound and 10 pound wire spools.
The 10 foot torch connection and electrode clamp allow plenty of choice for placing the machine in the work area, which lets you move around and do better work. One drawback with this particular machine is that to take advantage of the MIG process you have to buy a gas regulator. The same is true of the TIG process, which requires an additional torch, electrodes and gas mixture.
With infinitely adjustable wire feed speed and amperage controls from 10 amps to 140 amps, the Forney Easy Weld 140 can use these processes on sheet metal as thin as 32 gauge on up to 1/4-inch plate steel or MIG 1/8-inch aluminum with a spool gun.

The Lincoln Electric PowerMIG 210 MP is a versatile and powerful machine. It offers MIG, DC TIG, DC arc welding and flux core processes with a very wide output range from 20 amps up to 140 amps when running on 120 volt input and 210 amps on 240 volt input. At 20 amps, you’re able to weld as thin as 28 gauge with MIG and flux core, even thinner with TIG. At the other end, using 240 volt input, running 210 amps you can go to 5/16-inch thick steel plate.
One quality control issue with this machine is the wire feed spindle can be out of round, causing jams when the wire won’t feed smoothly. This is a warranty issue. Lincoln will replace it, but you need to make your claim while the machine is under warranty. The only other real drawback is the lack of a TIG heat control pedal.
On the plus side, Lincoln Electric is well-known for excellent build quality and durability. The Lincoln PowerMIG 210 MP continues these traditions and Lincoln backs this multi-process welder with a 3-year warranty.
6. Lotos LTPDC2000D Multi-Process Welder
- Plasma cutter, stick and TIG
- Able to weld 1/2-inch steel
- Dual 120/240 input voltage
- 50 amp plasma, 200 amp welding
- 1-year warranty
- Pulse width modulation
- Wide 15-200 amp TIG range
- High frequency no touch arc start
- 13-foot torch connectors
- Air regulator built in
- No TIG foot pedal
- Reports of build problems
The Lotos LTPDC2000D combines a 200 amp DC TIG welder, 50 amp plasma cutter and 200 amp stick welder into one machine. It uses either 120 volt or 240 volt power. 200 amps is enough power to weld 1/2-inch steel in a single pass. 15 amp TIG is fine enough level of control for confidence in welding 24 gauge sheet metal. 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.
7. Lincoln Electric LE31MP Multi Process Welder
- MIG, Flux-cored, Stick, DC TIG
- 30-140 amp welding range
- 120 volt input power
- Cast aluminum gear box
- Brass to brass torch connection

- 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.
8. Everlast PowerMTS 211Si MultiProcess Welder
- Dual 120 volt/240 volt input power
- Burn back wire feed control
- 10 amp to 200 amp output power
- MIG, DC TIG, flux core and DC stick
- 5-year warranty
- High frequency lift start
- 2T/4T trigger lock
- Adjustable arc force control
- Includes MIG and TIG torches
- Comes with TIG pedal control
- Some owners complain of poor service
- While stick welding, the MIG gun is live too
The Everlast PowerMTS 211Si is a very capable machine with MIG, flux core, TIG and stick welding processes. It’s a pretty advanced machine that works as either a high frequency no-touch arc starting when you use the included TIG foot pedal control or with a lift type arc start using the torch trigger. Everlast has equipped the PowerMTS 211Si with a 2T/4T trigger switch, allowing the torch to lock the arc on action for long welds.
This machine has what’s called synergic design, meaning that it automatically adjusts wire feed speed and amperage levels while you’re welding to maintain a better arc. The burn back feature resets the wire electrode stickout to the optimum length automatically when you stop welding.
While this machine offers an incredible value between multiple processes and a great equipment assortment with TIG and MIG torches and regulators, there are serious complaints with build quality and customer service issues. To be fair, there’s a 5-year warranty on the Everlast PowerMTS 211Si so it should be possible to work out any problems you might have along those lines.
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 savings 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 setttings 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.
