What Hypertherm models were non-inverter types?

go to see Welding Machine for What Hypertherm models were non-inverter types?

I know the MAX40 and MAX100 were non-inverters.What other models?ThanksTom

Reply:I'm pretty sure the PM 1000  was.  Mine weighed like 200 Lbs in the box with a long cable and machine torch.  I think you might look at the improved torch as a complete assembly, might be cheaper than repairing the older technology unit you have now.  If properly maintained and used the torches usually last forever with just consumable changes as needed.   I have had mine for the better part of 5 years and I am still on my third or 4 set of consumables, but I dont cut every day or all day when I use it.  Thats pretty durable even for the older tech torch.  Just a thought so you can get over slamming the best unit on the market.  Or you could just buy a 75K laser and be done with it all and really have something to bitch about...I'm spending my Kids inheritance, I dont like him that much anyway!!!!!!Enuff tools to do the job, enough sense to use em.Anybody got a spare set of kidneys?  Trade?

Reply:Thanks for getting me straight DSW it was the MM 210 that was so heavy and I wasn't sure about the transformer or PCB's in the PM 1000 since I have never had it opened up to look and clean it out.  I have been amazed at how stable the machine is and what it cuts in my Torchmate 4X4 table.  Definately a step up from a Hobart 250A with built in compressor.  That POS was just a toy compared to the Hypertherm.  Plus the support you get is outstanding and Jim is a very valuable asset to rely on when you need answers.  If I ever have to buy another machine it will be 80 or 100 amps and be a hypertherm.BobI'm spending my Kids inheritance, I dont like him that much anyway!!!!!!Enuff tools to do the job, enough sense to use em.Anybody got a spare set of kidneys?  Trade?
Reply:All the hypertherm units I have worked on were either chopper design or inverter.All the max unit except the max 42 I believe are chopper. the max 42 is an inverter,All the powermax units are inverters. Choppers and inverters operate at similar frequencies.Both are high speed switching units.Jim can help here. I don't know if hypertherm made a plasma that was transformer only, like he TD pak 5 or some of the century/ dayton/ snap-on units.
Reply:The HT40 was a drooper....non current regulated power supply...it was designed for HVAC cnc cutting machines for the ductwork industry...it was replaced by the HT40C which was a chopper design. A chopper power supply uses a pulse width modulated transistor (FET) to control output current accurately...allowing for current ramp up and ramp down....which leads to better consumable life.For hand cutting air plasma systems....the Max40, Max70, Max80, Max100 and Max200, as well as the Powermax190, 350 and 380 were all chopper based systems...meaning they are heavier and larger than inverters.  Of these...the Max200 is still in production and still very popular.All other air plasma systems from Hypertherm are inverters. Max41, Max42, Max43, Powermax600, 800, 900, 1000, 1250, 1650, Powermax45, 65 and 85.  Hopefully I didn't miss any!All of Hypertherm's current large systems, the HSD130, HT2000, HPR130, 260, 400 and 800 are all 100% duty cycle chopper based power supplies.Jim Colt
Reply:Jeez.....and I have a Powermax30 in my shop......a very nice inverter that replaced the Powermax380 chopper.Jim
Reply:Jim did Hypertherm ever make a plasma that was transformer only. like the TD pak 5XR
Reply:Yes...the PAK5XR was a "drooper" or transformer style......our HT40 was a drooper....transformer machine as well.....however we never offered it with a hand torch...only a machine torch.  The first hand held system from Hypertherm was a Max40 which was a chopper power supply.A chopper is still a transformer power supply...but it has added output current control for a more stable cut and better consumable life.The Pak5xr used two transformers...one was a 20 amp transformer, the other was a 35 amp...there was a 3 way output power selector switch to choose 20, 35 or 55 amps.The HT40 had a single transformer rated for 40 amps output...and used a large current dropping resistor for the lower, 20 amp output range.The chopper power supplies were conventional transformer designes but had a "chopper module" that would chop up the output DC into a square wave output at a fixed frequency (16 kHZ or so) and would adjust the on time vs off time of the square wave depending on the desired current output. The Max40 from Hypertherm was way ahead of its time......and definitely led the way to todays inverter plasma systems.Actually I believe Hypertherm had the first inverter based plasma as well with the Max41. It was pretty complicated and unreliable by today's standards....but I think we beat Powcon and T-D's stack pak to the market.Jim ColtLast edited by jimcolt; 09-27-2011 at 07:40 AM.
