The simplicity of the Forney Easy Weld 140mp is perhaps its best feature. It is essentially a three-in-one welding device that allows you to perform several welding processes with a single rig. It may be used for MIG welding, TIG welding, and stick welding. But why use up too much storage space when you can get one welder to do it all? TIG welding can only be performed in direct current mode.

But you can’t get anything more from a home welder. This also ensures that you will be unable to solder aluminum with it. However, the unit has a lift arc start, preferable to a scratch start because it protects the tungsten. It’s worth noting that the TIG gear is also available separately.

The strength of the Forney Easy Weld 140 MP is undeniably outstanding. Incredibly, the unit can have 140 amps at 120 volts. Multi-process welders, especially home welders, typically do not have that much control. You should expect to get 90 or 100 amps at best.

The Easy Weld 140 MP is ideal for first-time welders. It is straightforward to use and switch between processes. Only one switch can be set to three different settings: MIG, TIG, or Stick. It’s that easy! The only thing you have to do manually is set the polarities and the welding torch.


  • Compact to carry
  • Multi-process unit
  • Adjustable speed


  • Low duty cycle
  • Separate gas cylinder

Things to Consider while buying Welder For Automotive & Chassis Fabrication

Purchasing the first welding machine or locating a replacement can be a difficult task. The number of brands and types of welding equipment available from online welding retailers is daunting and can be a total minefield.

Therefore, we’ve compiled a list of important factors to remember while shopping for a new welder:

1) Power Source

The power supply in your workshop or garage affects the welding equipment you can use. If you only have a domestic 240V mains supply, the size of the welding power source you will use would be much reduced.

A system up to 110 – 130 amps will usually operate on a domestic supply with a conventional 13 amp 3 pin socket. Any larger, and you’re looking at 16 or 32A supplies, which are available for your electric oven or stove.

Welding inverters requiring more than 250 amps would need a three-phase power supply, similar to those used in manufacturing units. A three-phase electrical supply may be constructed in residential houses, but a qualified electrician must do it.

2) Inverter Welding Machine Vs. Transformer

There are now mainly two kinds of power sources for welding. There are the traditional transformer devices or the well-known welding inverter. Let us examine the advantages and disadvantages of each:

Welder with inverter – Inside, an inverter is similar to a computer and frequently has features that transformer machines do not, such as infinitely variable wire feed speed. These features can be helpful in fine-tuning during the welding process.

Transformer welder – These devices contain big and heavy Transformer Welder wound transformers, just as defined. The fact that these robots use tried-and-true technologies is one of their advantages. A transformer system is often phase governed, which means it is operated by phased switches rather than infinite control.

3) Cycle Of Duty

The duty cycle of welding equipment indicates how long it can operate before stopping and cooling down, such as 120A @ 35%. In this case, the welding system can operate at 120 amps 35% of the time. This is usually 5 minutes, but this unit will run at 120A for 35% of the time (1.75 minutes) before having to cool down.

In general, cheaper, less efficiently cooled power sources would have shorter duty cycles. This is a thing to remember because it will be rather inconvenient to weld a little, pause to cool off, and restart.

4) Weldable Material

What are you hoping to weld? This has an effect on the machine used as well as the welding process. If you’re welding mild steel, MIG, TIG, and MMA (Stick) will all fit as long as you have the right welding supplies. However, you must also weigh the setting in which the material is being welded, the aesthetics of the appropriate weld, and the process’s productivity rate.

If you needed to weld aluminum, you’d need either an AC/DC TIG welder or a MIG welder. I suggest a MIG welder because it is tedious, and you will need a spool on or push-pull torch and a pulsed MIG system depending on the aesthetics.

5) The Budget

The first and perhaps most important consideration when purchasing something is budget. You get what you pay for in life, so it’s vital to buy well and buy once. Look out for your budget first and checkout whether the machine you are going to buy is cost-effective or not.

Even though many cost variations are there, you have to buy whatever feels easy in your pocket. After all, you never want to buy something burdensome over your pocket.
