Convert Hobart Handler 135 to 175

Greg

Take a look at the parts list in your owners manual. The machines have several components in them that are different. The most important component right off the top that is different is the transformer. The input and output power on the HH 135 is much lower then on the HH 175. So, the manufacturer can cut cost on the HH 135 by using a smaller transformer. More then likely, if you try to run your 120 volt HH 135 on a 230 volt power source all you will end up with is a very expensive boat anchor after you have totally fried the machine.

Welding at higher current, as the 175 does, does not require double the arc voltage, so what you need is more step-down, along with heavier wire in the secondary.

Greg, I suspect that the transformer is different. You can post this at Hobart's site and see what the Hobart/Miller guts say.

Hell, hook it up and try it. What's the worst that could happen?

Is your insurance current? oooooooooo bad pun ..........

No, you can't. If you look in the parts list, you'll find that different transformers, reactors, rectifiers, gas valves, fans, and control cards are required for the

Reactors - comes from Reactance - based on XL from Inductance and XC from Capacitance. X = |XL-XC| is the reactance of the circuit at any one time. Based on frequency.

XL = 2*pi*F*L (Hertz*Henry)

XC = 1/2*pi*F*C

Anytime there is a reflection of impedance there is a reflection of voltage and current.

Therefore, current is always somewhere between pure resistance and the resultant X value.

It's another term for a power inductor.
