Is it safe to run Everlast welders from an engine driven welder.

[Jeremy]

I have a Lincoln eagle 1000 engine driven welder , Lincoln says it can be used to run inverter welder and plasma cutters ,but I can’t find any specs for THD. I have a good digital storage o-sope ,but I am not sure how to test the output other than to see if it looks like a sine wave without a lot of transient spikes. What experiences do any of you on the form have with running Everlast equipment from generators? I don’t want to risk a $1000 mig machine to get my answer until I have some more information. Can I protect the welder with some parallel MOV’s or a line reactor? I know what the manual says but what do you find that works in the field?


Thanks,
Jeremy

You could do a rough THD measurement by using a notch filter to remove the fundamental, then measure what is left on the scope. Also does your engine drive use an inverter for the aux power output?

I run my MTS250S mig and my 60amp plasma cutter off my miller 302 gas drive. I have had no problems running them. They work as good as if I had them on the grid. If your Lincoln states that you can run inverters from it then I can't see why it would not work. I used to run my Thermal arc tig/stick welder off a cheep chinese 5500 watt Harbor Freight generator with no problems.

I went to lincolns website and it does state that the Eagle can run an inverter welder but it does not state how clean the power is. I would call a lincoln dealer and insist that they get more info from lincoln than what the brochure states. They shold be able to tell you how clean the power is. But I think you will have no problem.

If lincoln says it will run inverters you are probably fine. I use a porter cable 5500 for the IMIG200 all the time. For me, the main thing is you have the amps (input amps) to match the welder. You have a good power source. But like said, call them and get the thd to be safe...

Just got the 185 tig and can not seem to find any info on how big a generator one needs to power this welder , thanks in advance for any I fo pointing me in theright direction
