The Best Multi Process Welder Buying Guide

Like any other machine you buy, you want to get a multi process welder that will last for years and get the best value for your money. When purchasing a multi process welder, here are a few things to look out for;

i. Versatility

The main idea behind a multi process welder is the ability to support different types of welding processes and remove the hassle of switching between different equipment. A multi process welder should be able to handle the basic kind of welding processes, and also it should allow you to switch between different processes easily.

Most units in our review support the basic welding methods, including MIG, Stick, and TIG welding, while some models can handle flux core, plasma cutting, and a few other processes. So, if you do a lot of welding, you'll need something that excels in every kind of welding and has a variety of features for different processes.

ii. The Display

Most multi process welders have a display for proper control of the inputs and outputs. Parameters such as wire speed and amperage can be controlled via the screen, while in other models, the display is used to guide the user through the setup process. Most models are equipped with a digital display, while others may have an intuitive color LCD display. Additionally, the simplicity of use should be a major consideration, so ensure the unit you choose is easy to set up and has simple instructions.

iii. Type of material

The type of material or the nature of your weld has a significant effect on the multi-purpose welder you need to buy. For instance, when dealing with aluminum, you'll need a machine with both AC and DC capability, so you might need to be more careful with your selection. When it comes to materials such as steel, most models are designed to weld handle steel and stainless with ease as long as you have the right consumables and settings.

Other than the type of material, the plate thickness is also going to determine the amperage range of the unit you need. For example, if you only need to weld thin sections, a machine that welds up to 140 amps is an ideal option instead of spending so much on a welder with a wide amperage range. The bottom line is that you need to identify the materials you work with most and buy a machine with excellent capabilities.

iv. Extra Costs

Multi process welder often comes with extra costs in the form of the accessories needed to operate the machine optimally and safely. These include various consumables for various welding processes, foot pedal for TIG welder, air compressor, among other accessories. You'll also need to consider safety equipment such as welding helmet, gloves, masks, and other equipment that helps to prevent accidents from occurring when working.

v. The Portability Aspect

Often portability is a main consideration when you need a machine to carry from one place to another. This is especially important when you plan to take on a wide range of projects if you intend to move it around the workspace often. On the other hand, commercial and industrial welding does not involve a lot of movements, so heavier modes are just fine. However, you can invest in a welding cart to help you move from one place to another. You'll also need to consider the working space so that you don't buy a large unit if you are working in a limited space.

A Final Word

From the above reviews, it is clear that multi process welders come in handy in various situations from professionals involved in more than one welding process at once to those unsure of the welding process they'll be involved in. They may indeed cost more, but they are worth the price considering their versatility. For users who want our recommendation for the best multi process welder, we suggest the Forney Easy Weld 140 MP multi process welder. This machine is a perfect mix of portability, speed controls, ease of switch between various processes, and it is the best in terms of durable construction. However, all the multi machines in our review will get the job done, so it all depends on the features you consider essential and your budget.
