Analog Voltage Gauge:

admin

Howdy,I've incorporated an analog current meter into my old Hobart machine which works fine and am wanting to incorporate the same type gauge for voltage. Should this thing be installed to read welding voltage, or power output voltage at the consumer receptacles? the receptacle power is 115VDC when the machine is run at high idle or during actual welding. It's never had gauges in the past and I've not used a machine with them so kind of a new thing for me.....Thanks,SlobPurveyor of intimate unparalleled knowledge of nothing about everything.Oh yeah, also an unabashed internet "Troll" too.....
Reply:They're installed to read welding voltage.Different manufacturers connect them in different places, but generally pick up OCV until the arc is struck, then drop to welding voltage. Ones I've seen connect between the rectifier and output terminals on static machines.Expert Garage Hack....https://www.facebook.com/steven.webber.948
Reply:Thanks man,These are NOS "Hobart" branded gauges and fit with the machine well. I installed a 400A shunt and it drives the current meter nice and linear for welding but haven't air arc'd as of yet. Should look pretty neat once everything is refinished and freshly stenciled. If I peg this meter I'll install a 500A shunt but don't think I will. Got my B model Mack welding rig started last week for the first time in a dozen or so years. Still runs well and will get onto the bed build pretty quickly with warmer temps being a large motivator.I have a job upcoming a little east of you and will look you up when in the area.SlobSlobPurveyor of intimate unparalleled knowledge of nothing about everything.Oh yeah, also an unabashed internet "Troll" too.....
