Hi, I'm new to the forum and also have limited experience welding.
I have owned this Sealey Supermig 150/5 for years now but have used it very infrequently, the last time being maybe 7 years ago. It's still almost like new.
My query is, when selecting zero on the wire speed controller and then activating the torch trigger, wire still comes out of the nozzle at quite a quick rate. Is this normal or should there be no feed at this setting. Turning the wire speed up increases the speed as it should right up to maximum.
The reason I ask is that when attempting to weld I seem to be generating way to much heat even with the wire speed at zero and the power setting at level 2. This causes blow through even on a new substantial section of exhaust pipe and it's almost as though the wire speed is too high and thus increasing the heat.
Does it sound like the controller or POT may be faulty or is it normal for wire to still feed when set to zero.
Thanks for any help or advice and remember that I am a rank amateur at this. Darryl
