Wire Welder

When we started to revamp our mad monk prop, we decided to make the legs much stronger by reinforcing them with metal.

This turned out to be our first project that involved welding.

David already had some experience with gas welding but was new to arc welding. Dennis had no experience whatsoever in welding.

Expect us to make a lot of mistakes!

Overview

A "wire welder" is a form of electric arc welding:

• A low-voltage, high-current power supply throws an electric spark (arc) between the torch and metal that you are working on.
• The spark causes instant heating, melting of metal, and blinding light.
• The welding machine contains a spool of special "welding wire" that it feeds out of the torch. This provides metal, flux, and a continuously fresh electrical contact.

Dennis Buying A Welder this wire welder at Harbor Freight Tools.

The grounding clamp attaches to the work, close to where you want to weld, but far enough away so it doesn't get in your way or get damaged by spattering metal.

Dennis does some welding, seen from the back where you won't get blinded by the arc.

Consumables

A wire welder contains a spool of special flux-core wire that is electrically charged and automatically pushed out of the torch.

This spool of wire came with the welder.

Replacement spools are readily available.

David loads the spool of wire into the welder.

Accessories

If you plan to do welding, you will need a way to pefrorm certain types of preparation and clean-up. You need an Angle Grinder.

You should also have a wire brush to clean the working surface, and some wire cutters to trim the wire coming out of the torch.

Buying A Welder

On our Philosophical and Social Issues page, we discuss some issues like name-brand tools versus house-brands, and inexpensive imported tools versus high-end tools. We raise the issue and let you make your own decision. We basically consider the cheap tools to be disposable. And that's easy to do with a screwdriver or a drill bit.

But what about expensive specialized tools like air compressors and welders?

• We didn't want to get something that is so poor that we would regret the purchase.
• We didn't want to spend large amounts of money for a machine that has bells and whistles that we may never use and might make learning hard.
• We wanted a michine that would run on ordinary 110 power for convenience. (That alone means it won't be a professional model.)

We came to the conclusion that an inexpensive wire welder from Harbor Freight Tools would probably be "good enough" for the foreseeable future and "good enough" to learn on without handicapping us.

After trying it out, we believe that this model isn't "disposable". It is a very competent "starter model".
