Htp Tig 201 Inverter

[klandor]

I Sold My Lincoln Sq.wave 175 So I Could Upgrade To A Bigger Machine, With A Little More Bells And Whistles.when I Looked At The Dynast 200dx And The Lincoln V205t Inverters The Price Jumped Up A Bit. While I Was Narrowing It Down Between Those Two ,i Found The Htp Company. Their 201 Inverter Seems To Be Comparable To The Lincoln And Miller Machines, But A Bit More Affordable. I Can Purchase The Htp 201 With The Cart And Torch Cooler For About 800 Dollars Cheaper Than Lincoln Or Miller.the Amp Rating And Duty Cycle Are Almost Identicle For The Lincoln V205 And The Htp 201. Anyone Have Any Experiance With Htp Or Any Of Their Machines.

I've heard great things about HTP machines. But thats as much as I know. Does that Inverter weld AC?

Klandor,

I have an HTP AutoMig. I have had it about 25 years. Parts and service are still available. I a;ways get friendly and knowledgeable people when I talk to them.

I only have used it heavly in the last couple of years. It is a 110v mig and I love it.

In January I bought their smaller scratch start tig. Hope to learn to use it at MM05.

If you are going to MM05, I might be able to bring it along.

I used a Lincoln 175 when I was learning TIG, and enjoyed it quite a bit. When buying my first machine, I went with a Miller Dynasty 200DX, and I have never regretted the decision. It cost a bit more than the other inverters out there, but the quality is incredible. The Lincoln V205 is not a cheaply built machine, neither is the HTP- but neither one is up to challenging the Miller. I weld 3/8 aluminum plate every day with the Dynasty, sometimes for many hours, and it has yet to run beyond barely warm to the touch. I've welded up to 1/2 inch aluminum using 75% helium mix, and while the machine was maxed out, it performed the task perfectly, and without complaint. You can weld MUCH thicker sections with an inverter, as you can adjust the waveform to be 99% negative, as compared to 68% for the older squarewave machines, as long as the material is clean. The 200 runs beautifully on 120V also. The first day I had the machine, I plugged into the wall and sat at the dining room table, fillet welding 1/8 inch aluminum coupons all night.

If I were buying again, I might have gone for the Dynasty 300SD instead, without the pulser. I find the pulser not terribly necessary, and have yet to have used it in a job where it made a difference in weld quality. And as I don't carry the machine around with me, the 120V capability isn't a deciding factor anymore.

Just make sure to get a good water cooled setup if you don't already have one. I run a coolmate 3, and a Weldcraft Crafter series CS310 torch, and After having to use an aircooled stinger for a week when I had a bad hose, I can tell you I'd never willingly choose to use an aircooled torch, not on Aluminum, anyway.

Do you have to a new machine with bell and whistles? A square wave tig 255 from Lincoln(older machine made in the early 90's) has the same bells and whistles that newer machines do, and is all digital to boot.I stay away from Miller, I have been welding with them for the past 3 years with different aerospace companies and have welded with everything from the dynasty to the Aerowaves, and personally think they are junk. Why? When welding on aerospace materials you can't have arc strikes on any part other than specified by blueprint (the weld area, and even that should have an arc strike) and the Millers arc is a hot start to get the arc going. I am not saying other companies don't do the same, but their arcs don't go all over the place.

Just my pennies.
