Tig cooler flow, Continous or intermittant

admin

Just wondering my the 330A/BP has a coolant flow valve on it which let's the coolant flow only when gas is flowing.Why not just have the flow run continously through the torch the entire time the cooler is on.    I am thinking about connecting the supply directly to the torch instead of going thru the valve as it seems it would be much less strain on the motor.  Other idea is have to let the valve wiring control a 110vac realy instead and turn the pump itself on and offTiger Sales:  AHP Distributor    www.tigersalesco.comAHP200x; AHP 160ST; MM350P,  Spoolmatic 30A; Everlast PowerTig 185; Thermal Dynamics 60i plasma.  For Sale:  Cobra Mig 250 w/ Push-pull gun.  Lincoln Wirematic 250
Reply:that valve is designed to be hooked up to a house water line and then the water waste water is just exited when the valve is opened. this valve should NOT be used at all if you are using a circulating cooler, it will damage the pump if the valve is closed while the pump is trying to circulate. if your using a circulating pump don't use the valve in linemiller 330a bp TIGmiller dynasty 200DX TIGmillermatic 185 MIGthermal dynamics cutmaster 101 plasma cuttersnap-on YA5550 plasma cutterhypertherm powermax 30 plasma cutterbaileigh CS225 cold sawetc....
Reply:+1   Don't use the water valve if you are attaching a recirculating cooler. The water valve is for using domestic water to cool your torch. If used this way the return water is dumped on the lawn, down the drain, etc.CharleyMiller MM252Miller Bobcat 225NTMiller DialArc HF / DIY Cooler2 Victor O/A TorchsetsMilwaukee 8" Metal SawMilwaukee Dry Cut "Chop" Saw 5 Ton Wallace Gantry Various Grinders, Benders, etc.

Reply:Thanks for the info as my welder has this solenoid as well.
