Blow Out Your Welder!

It’s a good practice to take the skins off your welder every so often and blow the inside out with compressed air. I do mine ever second roll of wire. Mine uses 33 pound rolls of wire, so adjust accordingly.

Metal dust can accumulate in the circuit boards and contacts and wreak havoc.

Dusty!!

 

Agreed! I worked at a tech school for a while and did this twice a year. Filthy every time.

 

Great tip, never considered that

One 33 lb roll is probably a lifetime supply of wire for me.

 

I think I have four of those rolls in this 3a alone.

 

Do the same with your air compressor motor. Blow all the dust out every now and then. A few months back, mine wouldn't start. The centrifugal switch had too much dust built up.

How practical would it be to add a filter?
It's a catch 22 from a manufacturer standpoint as to having a filter or not, typically boils down to cost.

 

I’m not sure. Every machine is different, but on mine in particular, I think a lot of the dust comes in through the louvered discharge vents and around the edges of the panels when it’s not running. So not only would I have to fit little filters on the front and sides in addition to the main rear fan, but also seal off all the panel seams with weatherstripping. Maybe it would make more sense on a machine with fewer vents and a tighter seal.

Then there’s the issue of weld spatter and grinding sparks burning holes through the filter media.
