Cold contactor safety feature keeps welding wire electrically “cold”

The Cold contactor safety feature helps to keep the wire electrically “cold”. Regardless of the type of welding wire, this safety feature ensures that the welder stays safe while welding. In addition, a cold contactor is a great choice if you don’t always want the wire to come into contact with the arc.

Flux-cored wire

When it comes to welding, flux-cored wire can make a huge difference. Typically, this wire comes in a thin strip that’s rolled into a “U” shape. The cored wire then has a cavity filled with flux. The seam is then tightly rolled closed. Some cored wires are butt-joined, while others are lap-joined. The latter is sturdier and protects the weld pool from moisture contamination. Typically, flux-cored wire is intended to be used with direct current electrode negative, but some flux-cored wires are designed for positive polarity.

Besides flux-cored wire, you should also invest in a good shielding gas. This gas helps in preventing slag, which is not good for welding. Additionally, flux-cored wires are much easier to weld because they have a smaller diameter.

Flux-cored wires come in a wide range of diameters, from 0.030″ to 0.035″. A 0.030″ wire will weld to a maximum thickness of 3/16″, but a 0.035″ wire will weld down to 20 gauge steel.

A high-quality flux-cored wire will provide a superior weld and improve your weld quality. The right wire will also improve the look and feel of your weld. You can purchase flux-cored wire at your local home depot.

Flux-cored wire is more expensive and may be difficult to clean. However, you can buy a more affordable, lightweight alternative, such as the Goplus MIG 130. This kit comes with a gasless welder, basic mask and brush, a spool of flux-cored wire, and a basic welding spool. It’s an ideal starter set to learn the basics of flux-core welding, but more experienced welders might want more power.

Cast iron

MIG welding is a versatile and easy method of welding metals. It produces a high-quality weld in a short time, with little cleanup time. In addition, it can work with metals that are difficult to weld using other methods. In particular, this method works best with thin metals like copper and aluminum.

An arc-150 is an ideal choice for home projects. It features AC generator power and is capable of handling 1/8-inch stick electrodes, up to 1/2-inch thick steel, and 3/16-inch thick steel in a single pass or multi-pass process. This welder also supports wire thicknesses up to.045 inches and has a high-quality arc for better fusion.

The Weld-Pak 90i MIG is lightweight and compact. It is suitable for beginners as well as professionals. Although designed for professionals, it is easy to use by anyone, regardless of skill level. It can handle basic welding jobs and can be moved from one location to another. If you want more power, you can opt for the Eagle 10,000 Plus. It features 10,500 watts of surge AC generator power and an LP gas hose. It also comes with a how-to DVD.


If you’re in the market for an aluminum mig welder, you’re in luck. This tool is perfect for home projects, light fabrication, and auto projects. It features a two-knob control, which makes it ideal for welding thin and thick steel. You can use it on both the top and bottom of a welding project, and it also has an adjustable heat control.
