Welding MIG? Flux Core? ARC?
 
I know that mig is the way to go as far as ease of use and not warping etc, but it just makes me sick to my stomach to think i have to spend 450 at least to get a crappy setup, When welding on my patch panels can it be done with a small flux core wire in a wire feed welder? What about a small arc (stick as I know them) welder? I want to be assured the welds will hold I dont necessarily care if i have to do more body work fixing warps and things of that nature, i would rather spend ten bucks on a gallon of bondo than and a week fixing things than $450 on a welder!! Any thoughts?

i bought a wirefeed welder for abot 300.its gas or flux core.The fluxcore wire burns a little deeper and the welds arent as clean.The gas in a bottle will last a long time if you remember to shut it off.Im on the same bottle i bought about 5 months ago and its still 60 percent full.With the gas its much cleaner.One can be had for about 250 from harbour freight and the bottle is about 40 full.I dont like the stick.too messy.

well i wish my wire feed was convertable to mig but it isnt get this it is a MIG brand what a rip off. Oh well it was free. THe only way i have found to turn my harbor freight into a mig is a custom tip!! Not somthing i want to play with! I am exploring the automotive glue called fusor right now sounds like i may have a winner, it is weld strength guranteed, no rust guranteed, two hour dry time and now worries (I am really concerned if i do weld i will do a crappy job and stuff will pop out on me!) Thanks

I also have an oxy acetalyne set up. Dont know if i can do anything with that? It looks like the fusor will not work on my shaved drip rails, so will any of the mentioned methods work for this?

Forget the glues and forget oxy/acetylene unless you are an EXPERT body man. You get what you pay for, plain and simple.

If you want to do this particular project right and and to do body mods for many years to come, invest in a quality MIG system. Your $400 will definitely not be wasted but will buy you most of a quality system like a Lincoln model 120 that will last a lifetime of hard use.

If this is a one-time project, farm it out to a pro shop, you will be bucks and headaches ahead.

70chevy 04-26-2004 02:22 PM

So you say farm it out... I have drip rails cut off, gas filler to be patched, rear cargo light hole, entire lower door patch, Door handles need to be shaved, sidemarker holes on bed, and a cowl that is in two pieces that need to be seamed together. How much would all that cost at a body shop? I would probally just trust that to the same shop doing my paint, but ball park what would i be paying?

Gas welding warp it like a wash board. Arc will blow hole right through it. Before I had a MIG set up I did it with a cheap 115 volt flux core welder. It can be done but you'll want to get a wire brush to fit in a 4" grinder and clean it very well. It won't leave as much flux as an arc welder but it still will be need to be removed completely.

crazy larry 04-26-2004 11:36 PM

for what that work would cost at a shop, you could get you a decent gas mig welder, do it yourself, and the next rod you do, well hell it's free! least thats how i justify it..... btw, i'm saving up for one of these. i started out with this but it ain't got the balls to do what i want to.....

here's one on ebay
more your speed
or this

get the baddest welder you can. you WILL NOT regret it.

That is what I Figured. I do plan to buy a welder but this is my first welding job, and I have 14grand in my truck already. I am worried that my welding might popout after two years. I could take it to a shop and get it back in a week perfect. I dont have to watch my lines every day and worry. What i was thinking If i could get the loacal tig shop to do it for 250-400 I would do that and have it done in a fraction of the time and perfectly. I just dont want to risk that i will screw it up. I am going to keep buying and building so i think i will practice on my next car which will not be nearly as nice or even close to as important to me as this truck is! THoughts, Comments?

Hey 70...you posted about starting your own custom shop... in order to get good and do well on rods and customs you HAVE to know the 'business' inside and out- meaning... ya GOTTA weld!! Get the best welder you can possibly swing- beg, borrow or sell something and practice, practice, practice. The investment will more than pay for itself in a short time and the experience will be invaluable. If you are concerned that you will mess something up the fear will stick with you and you will never succeed- GO FOR IT! Take the chance- I cut the roof off my car when NO ONE could tell me how to chop it- I just planned and figured it out. Spend your money on tools and not the 'bling-bling' like Play Station and DVD and big rims, etc. ( my opinion only- not dissing it just trying to help!) Get that experience and actually build it, others see it and want the same and you make the $$$ you need for bigger and better! Never be afraid of failure- success comes from learning by your mistakes and doing better the next time. Like has been said- 'Do it yourself and Save!" - the more money you give somebody else the less you have... good luck and get out in that garage and weld, man!! YOU CAN DO IT!! ( again- just trying to give you confidence and lead you down a winning road!):thumbup:

I'm normally a fan of learning to do it yourself but it seem that your under a time limit and you got so much invested in this that the job should be perfect. However when school is out of the way I would recommend that you try a complete do it yourself job. For your first attempt I would stick to rust repair or very minor crash damage. When your totaling up how much you've spent on a job there really is no way to put a dollar value on it when someone asks you "Who did the paint and body work?" and you answer I did.

Man....you sure got me confused! When you say you wish you could turn your wire feed into a MIG. A wire feed machine IS a mig or more correctly a short-arc. A Mig is a mig whether you use a gas shield or a flux core wire!

I'm sorry but if you keep complaining about not wanting the tools to do the job right, I'm going to have a hard time sympathizing with you. I guess I just woke up on the wrong side of the bed this morning.

yeah The welder I have is a cheapo welder and it does not have a place for gas output It is a harbor freight cheapie it is only like 110 bucks or somthing. I want to start but i just dont feel this is the place to do it. I am going to be welding all summer...My summer is filled with building fences. My GrandFather is going to spend a week teaching me to weld properly and then turn me loose. So i will learn the trade I am sure. A lincoln 110 is my next tool purchase. I have a lot of the rest of the body tools. Welder and a High VOlume air compressor will be about all I am lacking for basic necessities. I Have not decided either way which I am going to do (Farm out, Buy Welder) I am only vocally exploring my options. I have exhausted every means I possibly can to borrow a welder. Everyone is running arc systems around here (farm country). I will definitly keep on updating my situation here. I feel like I am not living up to a true "Hotrodders" standards.

I can lend my 2 cents..

I bought a Campbell-Hausfeld Mig welder off of ebay for 235 bucks with shipping. It took me about a month to get the basics down from sheetmetal to 3/16" thk. plate. I've replaced the front driver and passenger floor pans, the cowls vents, shaved the driprails, and am currently working on the rear quarters. I promise you, you won't regret buying one. You may regret farming it out if they do a crappy job that you have to redo later. I've been welding for about 3 months now and check out the fruits of my labor. I built this in about a months time and this project alone has paid for the welder and then some. (Hint: It's the rotisserie)

I little cash extra up front is worth it in the long run,

That is awesome. I get that i Need to weld I need to know what is going on. I am just learning mechanics as i go. My dad is the one who knows what to do there. I ABSOLUTLEY have to have this truck Finished by the end of JUNE. My dad is leaving for a month and wont be back until 2 days before i move out. I wish i REALLY REALLY wish that i had the time to do this myself. I just dont think it can happen! I have two months and I am starting two jobs Next Week. Every Spare second will be used just finishing what I already know how to do. I just dont think i can learn to weld well enough and finish what i need welded on my truck as well as what all else i have to do.

When I could only afford the cheaper 115 volt flux core welder I noticed that even though it had no gas valve it did have a set of plugs that a gas soleniod could be wired into and that the it had a place on the back end of the torch hose to plumb the gas into. Norther tool had a cheap generic conversion kit. The gas valve hooks directly to the cylinder and the wires follow the gas hose into the welder. I was still left with a live wire welder instead of a dead wire welder. I probably could have rigged up a contactor to work off of the same set of plugs but I've stepped up to a 230 volt machine.
