add a fan to an arc welder
HI
I just bought my first arc welder. I have been doing some practicing over the weekend. I found out that my welder only has a 10% duty cycle at 60A. I don't intend to do a lot of work with it, but thought if I added a fan to it I could get more up time with it.
If I add the fan would it need to be blowing into the welder, or out of the welder (extracting air).
I am a sparky and understand the normal saftey issues.
Regards
Paul

Added a fan to my Mig welder it is a 240 volt one that is about the same size as a computer fan. it sucks the air out of the welder but it sucks the air from about 1 to 2" from the main circuit board, works well and has increased the duty cycle a lot.

Paul, maybe try posting on the metalwork forum, Graeme frequents there and is a wealth of knowledge on welding issues.
Cheers........Sean

The fan will help but a computer fan is hardly big enough although the larger fan would help. It is much better blow the heat out of the cabinet. The fan used in the small CIG unit is a fast spin multi-blade volume air move unit. You will find your unit will have a longer weld time if you use it in cold air. Summer time on hot days the work time can be very short.

A 120mm muffin type fan ( they've been round longer than computers) would probaly be the go, they shift a good lot of air.
I would argue that blowing in would be better for a variety of reasons one of which is the ability to filter the ingoing air.
You may not get a great deal of improvement as the limiting factor will be the chokes ability to transfer its heat out to the surrounding air.
But for the small amout of trouble it would be to fit a fan its probaly wort it.Any thing with sharp teeth eats meat.
Most powertools have sharp teeth.
People are made of meat.
Abrasives can be just as dangerous as a blade.....and 10 times more painfull.
