Would A 90 Amp Flux Wire Welder from harbor freight work to fill in all the holes on a engine bay? im new when it comes to welding

 

It would how ever flux core wire (correct name), is VERY nasty wire makes lots of heavy splatter, and burns hotter depending on how closer wire is burning to tip of "whip". If it was ME i would not not do ANY flux core wiring welding on thin **** unless tou have years of practice with THAT machine. I am a cert welder and i would not use it on a bay

 

so wat do u recommend?

 

A true MIG welder with gas is the way you want to go. Unless you want to grind about 4x more than you really should.

 

.035 solid core gas wire. Looks copper but it is not copper. And mix gas.

 

I have the 90amp harbor freight flux welder. It does make a mess with slag. once you get the hang of the welder though you can lay a decent weld. Its good for what i need it for but would much rather have a real mig with gas. For the price though i't does the job on small things.

Ive noticed that it welds best on the high setting with wire speed 4. If welding thin materials it will over heat and blow through quickly on these setting but it seems to weld best there for whatever reason. Key to using this thing is good prep of you materials as with any welding and if trying to weld something thicker preheat it and it will work.

 

they told me that in 2 or 3 years i would have to do the bay again since it would rust from the inside out if i use it with out gas

 

Something like that you want a good welder.

 

good welders are pricey and dnt want to waste alot ofmoney on one sincei wont use it often

 

i did my bay with a hobart flux core and it was a messy process. it will splatter a lot but if you cover the area surrounding what you are welding you can reduce the amount of clean up. go at it with a propper grinder when you are done and it should look good. grinding takes a lot less skill than welding. as far as rusting from the inside out just make sure you clean and paint the back side of the metal you weld when you are done the welding will melt the pain on the back side off.

i think you can do it. just practice on similar size metal before you attack the bay and prep like you should.

also ask around your freinds and family someone might know someone with a welder that you could borrow that would be better than buying a cheap one.

thanks bro ill see wat i could do
i did gget disapointed when they told me not to use that welder it was my only hope since its cheap lol

 

I know you're looking at that welder because it's on sale right now and seems like the easy way out. You really don't need to spend a ton of money to get something that will do nice work, I have a Lincoln Home Depot special that's served me well for the better part of 20 years. I believe the modern equivalent goes for about $350, and you'll have a good tool that you can keep (or sell for not a ton of loss in value). The $100 HF job is going to be a piece of garbage in a couple of years, so you can count that as money pretty well throw away.

When I'm broke, I concern myself more with spending money wisely than with being cheap. I end up wasting a lot less that way too.

 

well atlongest the harbor freight one works ill be happy

 

You can find a good used welder for a little more than what your going to pay for the harbor freight unit. Mine is already haveing issues. The wire feeder doesnt feed consistantly and jerks the wire causing issues with welding. Its a constant battle that an unskilled welder will have difficulty with it. IMO i wouldnt buy this again AND I only payed for half of the purchase price as my buddy needed the welder more than I did and figured why not for a couple bucks but in the end left with a lack luster welder that makes a flippin mess of your materials your welding on.

 

See if you can find a used miller 140 or 135 they are great little Mig welders and you would be able to sell it again for what you bought it for and you would be really happy with the quality.

Also if you want to get crazy you can get a spool gun and weld aluminum.

 

HF works but I agree just get a used Miller or other name brand welder & you'll be happier. I was tempted by the cheap price tag ($100-120) and the fact that it plugged right into my standard home outlet, but it burnt right through the metal & was tricky to use.
I even had my buddy who is an experienced welder give it a try & even he struggled a bit at first.

I think the old saying holds true: "You get what you pay for".
