So I am welding in the Tangerine Racing inner consol reinforcement. If I have the welder set on three it doesn't bite into the ear. If I have it set on four it bites but it blows holes in the new piece. I was able to get two holes filled and they are definitely welded on. However, I am wanting to know before I do more if going on the four setting will be right and not damage anything. Three just doesn't seem to cut it.

I know this is going to sound silly but run a hundred foot extention for the welder and use #4 setting.

Really? (IMG:style_emoticons/default/confused24.gif)
Now what kind of extension cord are you talking about? |

If you turn it up to 4 can't you increase the feed rate to make up for the heat? |

the extension cord is actually good advice.
or... I'd set it to 3 and then turn up the wire speed with the 3 setting more wire speed equals more heat for me. |

I thought more wire reduced the heat?

Really? (IMG:style_emoticons/default/confused24.gif) Now what kind of extension cord are you talking about? Between the wall and your welding machine. Cuts down on the amps making it to your welder. |

(IMG:style_emoticons/default/confused24.gif) Now what kind of extension cord are you talking about? He's right... and it depends on the draw of the welder; but as a general rule of thumb the heavier the cord the better. If you just have a little home welder that runs off of 110, a 12 or 10 gauge extension cord should do it; if it runs off of 220 or higher, get your billfold out and be prepared to pay. Even a 25 ft cord can get expensive. |

Thankfully it is a 110 and I already have some heavy duty cords. Just needed to know what kind of cord. I have a 100 ft general garden type cord or two 50 heavy duty cords. I'll use one of the 50 footers (IMG:style_emoticons/default/beerchug.gif)

Isn't the longer extention cord going to blow the breaker?

Instructions, aren't they like asking for directions, anti-manly?

It would just burn back into the tip.
I guess I just start where I left it last and make little adjustments until I happy with the balance. Now I have to pull out some sheet metal and experiment. |

here are some tricks of the trade to help prevent burn thru:
CLEAN YOUR GROUND POINT BETTER. clean your weld area better. use a heat sink pc of copper or an AL backing plate to absorb some heat. put several clamps close to the area to suck out some heat. a stack of pennies under a clamp workds also. add small spot weld dabs to the surrounding area first to increase metal amount near area. this helps absorb heat. the 4 click number thing is voltage while wire speed controls amperage. increased wire speed increases amperage AKA heat to panel. |

pre-heat the area with a torch. it does several things:
removes moisture burns away contaminants that cause poping |

So are you saying if I have it on four but slow the wire speed that may help as well? The clamp thing makes sense as well. Thanks

not that simple. teh wire speed and voltage must match teh conditions. use teh guide as posted. back off on wire speed by 10%. your suspension ear is rusted from teh inside. the rust is iron oxide. teh oxigen expands violently. the pop blows the molten puddle away. I think the tiny spot welds to build up some material will be teh trick for you. welding to rusty metal is never text book proceedure.
the extension cord will make your welder put out less power on teh #4 setting but amperage will increase proprotionately...maybe, try it. my Miller digital welder is not fooled by such shenanigans. |
