    I think it will be OK as long as you're not doing long production welds. An Idealarc 250 is 50% duty cycle at 200 amps. I'm pretty sure they have a high temp. cut out as well.

    Re: Everlast plasma?

    Interesting thread. Funny how Harley Davidson got the Gov't. to put higher import tax on the larger displacement bikes coming from other countries. Then they tried and I think were successful in...

    Re: Fixing a bushhog...

    Hate to sound like a broken record but for 99% of any welding that will be done by the people on this forum, a rod oven for 7018 is NOT required. Keep them dry and don't store them in a high moisture...

    Re: Dump trailer hydraulics

    My old 3 ton dump truck hoist used the cylinders as a reservoir but also had a vented cap on the steel hyd. tank. Maybe this system needs a vent in order to fully extend? If it's single acting, the...

    Re: Fair Warning on DiscountHydraulicHose.com

    Just saw this thread and am wondering if the back ordered fittings are an odd type fitting that isn't very common? Maybe the factory had to wait for a production run or something? Seems to me like...

    Re: small dc welder for scratch start tig

    I don't know if Everlast has something or not but Thermal Arc which is now labelled Tweco has some small inverters than run on 120 volts. They have standard models and TIG models. I think the...

    Re: 7014 rod

    I think pretty much every stick electrode has something in the coating/flux that goes into the weld metal. All rods can pick up hydrogen. I think I read 6010 is actually more prone to picking up...
  95. Re: What is the trick to making leak free welds?

    There's a big difference between welding pipelines and welding hydraulic tubing. Hydraulic tubing is usually silver soldered and/or uses flared fittings.

    Re: Help me improve my welding...

    5P+ is a much improved 6010 over the original 5P. Lincoln added something to the flux to make them burn smoother but I can't remember what. It should say one or the other on the package but 5P isn't...

    Re: I had to pu the shield on.

    I can't see the other end so don't know if it could have been roll welded but looks pretty good for not having done it in awhile. A little touch up with a file on the edges and it will look really...
  99. Re: What is the trick to making leak free welds?

    Wait and see if the repair lasts over time. The tiniest bit of moisture, oil or back pressure can cause a pinhole. I welded a crack on a ripper frame on a cat and while it was cooling cracked open...

    Re: 7014 rod

    For probably 98%+ of the projects welded on here, hydrogen cracking won't be a concern and 7018 only needs to be in an oven when doing critical code welding. It has to be kept dry and away from...
