Welding Aluminum With A MIG Welder

Welding Aluminum With A MIG Welder

Steve Martin had a little bit that was like a faux infomercial wherever he suggests, “You can be a millionaire and hardly ever fork out taxes!” The guidance ended up, “First, get a million pounds. Then,…” [Brandon’s] instructions for how to change your MIG welder to do aluminum for less than $25 is not rather like that, but you do will need the correct variety of MIG welder to make it function. In individual, you need to have an actual MIG welder that has a provision to link exterior gas. The recommendations display a Hobart Handler 140 that meets the criteria and has enough electrical power to tackle aluminum.

The principal process is to exchange the liner for the torch. The stock liner is metal which is fine for its intended intent, but it is much too tough for aluminum wire. A PTFE liner is reasonably priced and will work fantastic with the aluminum wire. If you want to do regular welding afterwards, you are going to need to set the primary liner back again in.

The other point you will have to have is argon fuel and the welder desires to be configured for good wire and gas. The chart in the welder demonstrates that you can use it for aluminum, but it does mention that it is challenging to feed with the stock liner.

Aluminum wire expands as it heats, so you require a a little bit bigger suggestion than the wire size. For example, in the online video, [Brandon] works by using .030″ wire and a .035″ tip. The reasonably minimal amperage and duty cycle of the welder necessarily mean you need a compact wire dimension.

Did it perform? It did. He did preheat the get the job done to enable the compact welder get the workpiece to temperature. It took a minor experimenting to get the ideal angles and procedure. In the finish, he points out some of the gains of possessing a equipment meant to weld aluminum. On the other hand, for occasional use, this looks like a sensible modification.

In some cases welding requires a big bang. We don’t know how to produce our personal argon, but we did see anyone make their personal carbon dioxide shield gasoline, not long in the past.
