Powermax45 torch control relay

[planescott]

Hi everyone,
Im wanting to find out before I buy the powermax45 with mech torch will I be able to operate the the torch on/off with a relay here are the ones I have on my breakout board, The ratings marked on the relays are: 16 amps at 120 VAC, 8 amps at 230 VAC and 10 amps at 30 VDC.

Also i am mostly going to be cutting .125"(mild steel) and thinner can the pm45 be used in a 220v/30amp receptacle if using at 30-35amps would that give a good cut on thinner material or is it best to always cut at 45amps like the charts show.

thks scott

You can operate the Powermax45 with machine torch on your breakout board output relays. The input start circuit uses less than 1 amp. The input amperage draw of a Powermax45 is rated for cutting the maximum production thickness. If you cut thinner materials, even at 45 amps output...the input amperage draw will be less than the data plate indicates. A bit of a guess here, but I suspect you can cut 1/4", maybe 3/8" all day long on a 30 amp 230 volt input power circuit.

There are two sets of consumables for the Powermax45, a 30 amp set and a 45 amp shielded set. As with any plasma, best cut quality is at the nozzle (some call it a tip) design max amperage as this produces the best energy density.

Thks for your reply Jim,

I suppose if the relay is rated at or above whats needed it wont hurt anything?

Correct. All the relay does on your breakout board is to activate the electronic start input on the plasma.....just like flipping a switch.

ok Cool, Thk you very much Jim!
