View Full Version : Weird Sound from Welder
07-09-2007, 08:23 PM
Ok, I was out today working on some pipe and was expecting a good job. Then I noticed something not right. When I would begin to weld, the welder seemed to surge. It didn't maintain a consitent sound or weld. The surge was kind of like a car idling and then you would rev it up and let off and it would come back down. It would try to show me a puddle and the suge would hit and wipe it out and the process started back again. Can anyone give an idea thsi would be. Thanks you

I have no idea but couldn't even make a guess without knowing what type of welder you are working with.
TIG or stick? Engine driven? Pedal or no?

the machine is a 100 fluxcore welder. Runs off of 110 household power. Has a high range and a low range as far as dialing them up or down.

What brand 110 welder is it ?

Is it a hf brand? I have that one:rolleyes: . It might be something in an internal circuit boards but dont have alot of exsperience with that kind of stuff.

Whitey, if you are using an extension cord, try it plugged right into the wall outlet, and see if that makes any difference. Some long cords with small wire can really choke down power tools and welders, and are not to be used. :)

ok I think I may have fixed it. 1. The extension cord was to long, so I plugged up the unit straight to the socket itself. Tried again and no real progress. I then changed out the contact tip and BANG!!! This welder took off like it is suppose to do. Super Power for a 110. I guess I need to get another extension cord that is smaller, and buy some more of those contact tipsl Thank You.

More contact tips is a good idea, especially for a beginner. I hope when you refer to a "smaller" extension cord, you mean shorter, not smaller gauge wire.

Ive also noticed in the hotter months (like right now) the voltage runs lower here at my location (neighborhood). This really runs havoc with 120v welders. Do an experiment, try welding about 6-7am and then around 5-7pm. See if you notice a difference. You could also take voltage readings at the outlet before and during welding. This information may provide you with an answer. Uncrichie.
