Weldpro 155 MIG Welder – Top Features


The Weldpro 155 is full of exciting and useful features that you can make the most out of your projects. From small to medium and large projects – the Weldpro 155 is the perfect suit for any project on the go.

Let’s find out the top features of the device that you can make the most out of for any project to come!

Multiple Power Input

The first and foremost feature that matters the most is the multiple power input option of this device. It can be easily set with both 110/115V power source and 220/230V power input.

That means it’s capable of working in both household and commercial connections. It doesn’t matter if you are working at your own backyard garage or at your commercial welding area – Weldpro 155 has got your back.

You can carry the device around with you wherever you go and simply connect it to regular power input, and you are ready to roll! Interestingly, if you don’t have a power output of 220/230V, you can easily convert it to support the output, as well. There’s a simple hack that comes with the device package.

It’s a useful converter that can easily convert any output into 220/230V output so that you can easily get the device connected. It’s really awesome and using this device is really fun and useful.

Compact Design

While most lightweight welding machines in the market are just claimed to be lightweight, Weldpro 155 is actually a lightweight device to work with. Weighing just about 21 pounds, the device is one of the lightest welding devices we have ever come up with.

Apart from the weight, the welder is also pretty compact too. Its 14.96 x 13.58 x 6.69 inches’ dimension gives it a pretty sleek look and profile. It makes it pretty convenient for you to carry it around in the car and simply move around with it.

Being impressively lightweight, the device doesn’t put a lot of pressure on the hand, either. Its straight steel-rod handle on top makes carrying the job ever easier. All you need to do is just pick it up and move. The smooth steel construction doesn’t let your hand slip away from the handle at any time.

IGBT Technology

Weldpro 155 welding machine is equipped and powered by IGBT technology to make it even more powerful than usual devices out there. The IGBT technology is a bipolar transistor that comes with a gate terminal for insulation.

The IGBT applies a MOS structure having a control unit – both in a single machine. As for the bipolar transistor, it simply acts as the output switch.

With the IGBT technology working in the device, the Weldpro 155 offers better performance than any usual device. It can easily produce higher power results with lower-power input. So, in reality, technology saves power, as well.

Three Welding Choices

Using the Weldpro 155 welding device, you can easily weld in MIG, Stick, and Flux-cored welding techniques. That’s why it gets easier to weld on 1/4 inch mild steel pretty accurately. Apart from mild steel, the welder is also capable of welding stainless steel and aluminum, as well.

Proper Ventilation

The front side of the welder lets the hot air out of the device to keep the inner parts of the device cool. You can feel the heat getting out of it just to make sure that the device doesn’t get overheated. That’s one of the multiple safety measures that the device uses.

If you rotate the device and check the backside, you can see another large opening that also works to evacuate hot air from the device. There’s a fan attached to provide extra cool air to keep it under normal temperature.

Apart from overheating protection, it also has safety precaution systems for overloading and over-voltage issues too. It’s kind of self-sufficient to help itself out in the case of danger.

Easy Knobs

The control knobs on the front are pretty easy to use and quite simple in design. There are only two knobs to control the flow of Volts and AMS, which is quite a brilliant display from Weldpro. It reduces the chance of you getting confused with multiple buttons and knobs.

Just use the knobs to turn right and left and get the correct output as you need for your project.

Simple On/Off Switch

First of all, the device comes pre-assembled when you open the pack. The hose, the torch, and the welding machine – are all properly attached and come as a ready-to-use set of welding solutions.

Then again, if you are wondering if running the device is a daunting task, you are wrong. There’s an On/Off switch at the back of the device that you can simply click to turn the device on and off.

The red button is quite visible, and you can easily see it even in the darker areas. It makes it extremely easy to control the device on the go.


The Weldpro 155 comes with proper steel construction that gives it the due durability and ruggedness it needs. Don’t be deceived by the lightweight profile of the welder; it’s quite rough and tough in nature.

You can easily carry it to your welding construction site and use it without any delicacy – the welder won’t tear out easily. You can trust the build quality from Weldpro without a doubt.

Long Power Cord

No wonder the power cord of the device is long. The 4 feet long cable works perfectly for you if you are working on a project that needs you to move around the working zone.

You hardly need to move the welder from its place most of the time. The cord length is enough to help you move around and carry on your task without shifting the actual device from its place.

This is super convenient for professional users who need to work on multiple spots in a single area or room.
