weld not penatrating

[Tofudude]

well i hope i spelled that right, any ways i got a miller 130 and i was using it to weld my sliders on. As i tried to weld the sliders to the frame it stuck on, but a quick jump test showed that the welds broke clean off. When i welded the tubes to the actuall slider those were super strong and the actuall welding process was rather smooth compared to when i was welding to the chassi. I was wonder if it was the welder not being strong enough to penatrate or if it was a ground problem and ideas? (paint was brushed off when this was done)

Grind the paint off so its clean, get a good ground and set the welder tto the proper settings

[mkyhmltn]

Was the paint removed where you had the ground attached too?

[Tofudude]

i did grind the area where the ground was connected to and the area that was to be welded.

forgot to mention the circuit breaker kept going off when welding the sliders to the chassi but not when welding the tubing toghether.

That's always a pain in the ass.  Are you using an extension cord?  Cause that will do it sometimes

Weld vertical up, practice before hand, see how hard it is to break, weld one side only on some plate. You should be able to do it no problem with that welder. If needed, preheat. Its fusion you arent getting btw.

X2. I used a little miller to sas my runner, and then purchased a lincoln 140 and have had absolutely no problems.

Do you have a picture of your weld? we may be able to get some more information from it to help you figure out your problem, whether it is a technique issue or settings issue.  Another thing to consider is if you are using a shielding gas outside in a windy condition your sheilding gas may be being blow away and not providing what it needs to which would lead to a crappy weld.

I am no welding expert by any means and don't necessarly know all the problems or terms, but I can weld what I need to.  Just trying to help you out, I don't mean to come off as a smart ass or condesending.

x3 listen to jerry he knows his

I'll collect some scrap metal i got and give it a go. As for the power supply even directly connected to the clothing dryer socket, its triggering the circuit breakers. all snap a photo for you dingman tomorrow.

thanks for the help also

Is the dryer 110 or 220?

[Cheesemaker]

A quick search of a Miller 130 shows that it is a 110 volt welder.  And I'm not a welder, and have no experience, but that welder is more for thinner metal.

[mudmaster]

A 110 welder should be able to do it.

[Dingman.]

Not should.  It will do it if its a good welder and the welder has the skills to do it.

[junya92toy]

110 is just fine for that.

[pumkin toy]

a 110 welder will do it just fine but you will deffinately want it set to the highest setting for what you are doing.  sounds like when you were welding the sliders to the frame, that the majority of your weld was laid down on the tube without an equal part on the framerail. Most of the voltage (heat) probly penetrated the tube and didnt actually burn into the framerail.  try focusing the wire more on the framerail and flowing the bead down onto the tube.  it sounds like you have done everything else right (as far as cleaning and prep).  try it again and see if you can get it to burn into the frame better

[Bigredwelder]

Coming into this one a little late.....one question I noticed wasn't addressed was what type of shielding gas you are running?  As long as everything (welder setting, technique, prep, etc.) are done properly, you should not be having this issue.

Posting a pic or two may help.

Depending on if you are using Solid wire or Flux core you have to change the polarity in the Welder to either DCEP or DCEN. This may or may not be your problem.

[Tofudude]

everything has been setup correctly, found out the socket that was assumed to be the 120 socket for the dryer was actually a standard one or something, swapped the plug to the actuall one and now the welder works like a charm. i feel slightly stupid-er lol

[Bigredwelder]

Hey, at least you figured it out! 

[81 toyota]

hey when welding on the frame rails weld verticle down aka down hill it is a less strong but if you weld up it can screw up your frame rails

[IronClad]

but if you weld up it can screw up your frame rails

... What?

[mudmaster]

 

[yotaneck13]

thats my problem

[junya92toy]

I think he means burn a hole in the frame, if you do its not the end of the world, let it cool off, then just put some weld on the edge of the hole for a sec, let it cool, and keep doing that over and over again until its filled. To keep from burning through, travel a little faster, turn the welder down a little, and remember when welding up, you have to move side to side, pause on the edge for a sec, but do not stop or pause in the middle.
