Hi posted this in another part of forum , didnt know which section would be appropriate !, , just bought a ( chinese ) welder of e-bay , seems to run o'k' , the rather poor user manual says it has automatic thermal protection , and a cooling fan . What id like to know is does this fan operate continualy , or does it engage after a certain operating temperature is reached ?. The welder is branded Air Tuff 250amp arc welder ( model/ bx1-250c ) , i have welded three 4.0mm rods at 150amps and fan did not engage , actually the machine did not seen to get hot and the welds were good on 6mm plate
