input on the a tig machine for pipe welding

admin

Hey guys i am looking for a tig.machine for use in my training of one.day welding pipe in refinery . Now in my class they have miller synch 250. And I hear great things about them. Since they are out of my range I found a miller econtig on Craigslist list for 600.00.  Is this.machine a good choice to learn how to tig pipe ?? From what i hear air cooled machine are the choice for refinery welder. In my opinion I want.to keep it.close.to.the same machines that are used in the.field.  if that makes sense to you guys.

Reply:If you're looking to learn how to weld the piping trhat is out in the plant, you should learn scratch start TIG. Any decent Stick machine and an air cooled TIG torch (I generally use a 17) will work. I work in a Power Plant, not a Refinery, but I would think they are similar.
Reply:For pipe I like the miller maxstar. Make sure to get the analog not digital version. You want a llmachine with lift arc. A standard stick machine will light when you touch your tungston to the pipe, with lift arc it lights after you pull the tungston back off the pipe. It keeps you from blowing the tip off your tungston. No foot peddle is needed for carbon or stainless. Just set your amps and weld.
Reply:I only see one down side to the Maxstar for pipe training. That's the fact it will not run 6010 rods well. If you are only looking for a DC tig machine and a machine to run 7018, it's a very nice little machine. If you are also looking for a machine that can also run 6010 root passes, it's probably not the best choice.$600 for an Econo tig is fair to high from what I've seen. I've seen a lot better machines for just a bit more. Several guys here have picked up older Syncrowave 180's for as little as $800-1100, Syncrowave 200's for $1000-1400, and even a few Syncro 250's in the low $1000-1500 range, though they are probably much rarer and older machines. You can also usually find some of the bigger older tigs in the $600 range with a lot more options, like Zap's Miller 330 AB/P and some of the Lincoln and Hobart Tigs I'd seen guys pick up in the $500-900 range..No government ever voluntarily reduces itself in size.

Reply:The thermal arc 161STL would be a good alternative to the maxstar 150. Picked one up last week, does fine with 6010- did some pipe the day after I got it.
