high freq box question?

admin

I have a M250-1 high freq. box I use with my trailblazer to do occasional aluminium work. I have a miller maxstar slt 150 I like to use in the shop. Can I link my maxstar with the high freq box and weld aluminium? I read somewhere that the inverters do not require ac to weld aluminium, is this possible?Miller TrailBlazer 251Miller HF-250-1Miller MaxStar 150 STLHyperTherm PowerMax 380 plasmaLincoln PowerMig 180Millermatic 252Miller Diversion 180
Reply:Wow, alot of confusion here.Your Maxstar has DC output only.  No need for high frequency on DC, unless you want it for the start, but your 150STL already has lift start.Some AC inverter tigs don't use HF to weld aluminum.  Your Maxstar is not an AC output inverter, so that has no bearing on your machine or situation.Yes you can tig aluminum in DC, with helium gas on thick plate.  Still don't need a high freq unit to do it though.  Not many people tig aluminum with DC.  AC is the preferred and common way to do it.  Get with member WIlliam McCormick if you want to learn about DC aluminum tig, he does that often.  I tried it and it was complete disaster.  Also, your high freq box, if it is a Miller, is called an HF251D1 or 2, depending on whether it runs on 110v or 220v.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
Reply:thinks guys for the info. My HF unit is a miller hf-250-1, it has the five pin connector and runs on 110v. I have always used hf on aluminium an assumed it was a per- requisite.Miller TrailBlazer 251Miller HF-250-1Miller MaxStar 150 STLHyperTherm PowerMax 380 plasmaLincoln PowerMig 180Millermatic 252Miller Diversion 180
Reply:I don't have the HF box.  I didn't know they made a 250 model.  Thanks for clearing that up.I could just imagine all the water shorting some big capacitor to ground while standing in the puddle of water in flip flops...   I'll stick to pressurized air.

Reply:Wagin, no, I'm not a Miller rep, I'm just another fool tryin to make a living melting metal and like using their equipment to do it with.     Millermatic 252 will do for the spray transfer.Steve, haven't had much work for it but I am happy with the Optima.  Still haven't fooled around with solid steel wire with it yet.   I don't expect it will be much different than the 350P with steel wire.I'll be sure to dry em off real good if I get the idea to use the hose the shop machines.   The Bobcat gets hosed off when I wash the truck.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
