Massive mig welder hell to move

I guess the only way to find out is to use the thing.

Good idea.

One thing with these cheap welder they never tell you is about a thing called duty cycle.

Duty Cycle is how long you can use it at what setting. Look on the plate at the rear and it should give you some figures as a percentage.

The adverts says 150 amps but Screwflicks blurb says 140 amps for this model ?

So just guessing it will say something like 70 A @ 100%
90A at 80%
110A @ 60%
120A @ 40%
140A @20%

What this means is that the % figure is based on 10 minutes, so at 70A you can weld all day and at 140A it's weld 2 minutes, rest for 8.

For obvious reasons they don't make a big fuss of this. The more you pay the higher the figures.
