Lincoln Electric le31mp Review

MIG welding has become the go-to choice for metal fabrication across industries around the globe. In fact, it’s estimated that more than 50% of the world’s vehicles are now being built using this method. As a result, Lincoln Electric continues to develop new MIG welders at a rapid pace. Today, we’re going to take a look at their latest model – the LE31MP. Let’s see if it meets its promises.

Which is the best aluminium mig welder Australia?

A basic household or hobbyist electric welder uses two electrodes (or rods) that touch the piece being worked upon. These wires or rods are connected to a power source which then allows electricity to pass through them into the material they are touching. In order to create sparks or heat necessary for welding, these electrodes are usually fed through a high amperage current that generates enough pressure to break apart atoms of the metals involved.

Power Source

This lincoln mig runs on a 120V power supply unit with a 20A breaker, which eliminates the 240V limitation, and it can weld in a lot more locations, making it really portable, as we said above as well. This device outperforms most of its competitors as it’s able to produce 95 amps at just around 60% power, which is quite impressive.

Wire Drive System

The wire drive system is very reliable and efficient. It provides a constant flow of wire so that you don’t have to worry about feeding it manually. You can simply connect it to the spool and start welding.

Welding Speed

This device offers a maximum speed of 10 meters per minute and a minimum speed of 0.5 meters per minute. That means that you can work on small pieces without having to slow down too much. [2]

Welding Quality

The quality of the welds produced by this device is excellent. You won’t find any weak spots or gaps in the welded parts. Even if you compare lincoln le31mp vs 140mp you’re still not going to see that much of a weld quality difference.
