Chicago Electric Flux 125 Welder – BUYER’S GUIDE

A few key points should be considered when shopping for a welder to ensure that you get the right one. Our welding buyer’s guide outlines the most important points.


The most important feature of a welder is the power rating. Welders come in a variety of power ratings, ranging from roughly 25 amps up to 250 amps. Higher-power welders can weld thicker metal faster.


Amps measures how much electricity the welder uses. Higher amp welders can deliver more power to the welding rod, which allows you to weld thicker metal faster.


This type of finish is very durable and offers great protection from corrosion. This is my personal preference because it looks better and lasts longer.


These finishes provide excellent corrosion resistance, but the welders won t look as good as those with powder coat finishes.


The best welders are easy to use because they have switch settings that can accommodate different types of steel. Look for welders with multiple voltage settings for different types of steel (i.e. 0.8 amperes for mild steel, 1.25 amperes for stainless steel). This will allow you to use one welder on many different metal types.


There are two main types of weld switch types, push-button and dial. Push-button switches are easier to use because you just press the button to activate the weld, but dial switches allow you to set your voltage and amperage manually, which can enhance your control over the welding process.


Some welder models offer dual voltage capabilities, allowing you to switch the voltage between 110 and 220 volts. This is useful if you plan on using your welder both at home and in a workshop where the voltage is different.


The best welders come with warranties of at least five years. The warranty will protect you in the case of manufacturer defects.


The weight of the welder will determine how easy the welder is to move around your shop. Larger welders can weigh more than 100 pounds.


Some welders come with built-in capacitive touch sensors, which make it easier to turn on the welder and reduce the possibility of sparks. This feature is mainly useful for push-button switch models.


The noise level depends on several factors, including motor type and build quality. Lower-range noise levels are possible (usually under 100 decibels).


Welders range in feature range from simple arc welders to complete electric flux welding machines with options for customization and advanced functions such as pulse control.


The welding rod is fed through the wire feeder, which controls the amount of wire that goes into the weld. Weld thickness can be controlled this way.


Heat control allows you to adjust the temperature of the welding wire, which allows you to control how hot the metal becomes during welding (materials will change properties when they reach certain temperatures).


Some welder models include fusion tubes, which are cylinders made of heat-resistant material that can be heated and used to weld curves without disturbing the alignment. This feature is useful for making jewelry and architectural projects.


A weld cup encloses the end of the welding wire, allowing you to weld on surfaces such as steel plates without having to stand in a puddle of water. The cup also creates a perfect seal when welding on flat surfaces.


A tube clamp is a device that clamps around a welding tube to secure it in place.


Some welders come with built-in capacitive touch sensors, which make it easier to turn on the welder and reduce the possibility of sparks. This feature is mainly useful for push-button switch models.
