Protection against a dust

[donor76]

Hi All,
For workplaces and shops with high dust pollution, for example, the grinding dust, many manufacturers the welding equipment recommend (as additional option) to use the dust filter.
I work in enough dusty facility, from here and a question-
whether it is necessary to me to make the filter on my рр256?
On mine EWM pico 162 I use such ( buy there was no possibility, made myself)

Building your own pre-air filter should be okay, as long as , the intake surface is so large that it couldn't possibly plug up and restrict the air flow that cools the machine. Dust and sawdust are always a problem.

I understand that it is necessary to watch the filter and on a regular basis to clean,
Which I wish to do the filter very simple in service

Today has made the filter
All works perfectly,
electronics is protected

It will probably reduce the duty cycle some, which will probably create some early thermal tripping and slightly longer reset times, but it should keep everything internally cleaner...

Donor,

!!!!! PLEASE Do not use that. That filter is way too dense and interferes with the free flow of air. Also the grating/mesh that holds the filter has significant obstruction and I'd guess it is at least 30% reduction from just that! Ours are not engineered to have any obstruction.
The 256 has a low duty cycle as it is at max. You will damage the machine seriously.
ANY air restriction is forbidden and will void warranty. You must keep 1 foot clearance from any obstruction additionally to provide maximum air flow.

It's better to remove the cover occasionally and blow out the inside with an an air compressor, and and air gun/wand.
