I started welding on an old buzz box that was parked in the corner of our shop for as long as I could remember. The paint was scratched and the faceplate was barely legible. But, it worked. In fact, that old buzz box is still burning rod and making equipment repairs today - almost 20 years later, without a single repair. Now that's impressive.
Traditional welding machines were very simple devices. Even the most advanced used the same basic design. They were constructed of a steel core wound with copper (and sometimes aluminum) to transform high
voltage shop power into high amperage welding current. Machines used off-the-shelf parts like diodes, relays and potentiometers for various process controls. Even AC square wave and balance were
possible with these simplistic designs.
sources. For the most part, that's a good thing. Inverters
provide more output control and can help on tough welds. They also tend to be smaller and lighter weight - so they're
more portable and easier to move around the shop or jobsite.
require a trained technician familiar with electronics to for proper diagnostics and successful component replacement. Fixing an inverter is not as simple as changing out a relay or swapping a potentiometer. No, repairing an inverter requires a precise and methodical approach ... and often
involves replacing high-tech PC-boards, IGBT's and other expensive components.
If you're in the market for a new machine, make sure to consider the total cost of ownership and include repair after the warranty period. You should also have a preventative maintenance program in place with a trusted service provider so you can increase the life expectancy
of your machines.
