weld pak 100

admin

have a lincoln weld pak 100 that i will be converting to gas but my big question is would i be able to weld car frames with it and if so what type of was mixture should i use to get beter penetration. just need to do 1 frame,not for every day use.
Reply:Have you compared the stated metal thickness capabilities of the welder to the thickness of the car frame metal you want to weld?  If you're welding 3/16" or more, it's likely that no gas mix will give satisfactory penetration for that welder.  These small 115VAC welders usually can weld thicker metal with flux core filler wire versus gas anyways.  If the proposed frame weld is critical and/or load load bearing I'd be looking for a higher amp welder and possibly some professional help.TeddCoHTP Microcut 400 & Invertig 160DC  Smith Dual Guard MD-510 OA Rig  Lincoln SP135+  Hobart Stickmate LX 235/160
Reply:I think you'll need to specify what part of car frames you want to want to weld.If you want to cut, shorten, and reweld car frames... the answer is no.***************************************Lincoln AC225 stick welderLincoln HD100 WeldPak flux core wire feed welderThree of the cheapest grinders money can buy
Reply:well i want to cut and shorten a frame but i got confuse when i seen some other people talking in this forum that the weld pak can weld 1/4 thick metal and might be able to handle 1/2 with gas but i will just wait untill i upgrade to a biger welder
Reply:I want to say the thickest rating is 1/4".  No way in hell you'll be good to 1/2"Most frames are only around 10ga so I believe you'd be ok assuming you know what you're doing.  Probably have to have some splice plates too.  The fluxcore wire will be hotter.DewayneDixieland WeldingMM350PLincoln 100Some torchesOther misc. tools
Reply:co2 gas is said to have more penetration then fluxcore. would that be a better way to go?

Reply:thanks guys for the info
Reply:Since you already have the welder, and since you will likely get more penetration with flux wire, why not just find a local fab shop that will sell you some scrap cheaply and get some of the same thickness as the frames you intend to weld and try it. Or, if you have an old frame piece try it on that. Once you weld some cut it apart and otherwise bend fold and mutilate it to see what kind of penetration you are getting. This will convince you one way or the other.
Reply:I have used my 100 pak to do some welding for my truck parts.  I made a set of rock sliders with it.  I can jack the truck up by thiese sliders with no problems.  I have done 1/4 inch with no problems.  Just gotta burn SLOW and make a few passes.  I use flux core.  One of these days I will be doing a rear bumper for the truck, but that I will probaly just tack then take elsewhere to have it done right.  BTW I never welded before I bought that welder.
Reply:Ok heres my input, i know a sp100 is rated for thin welding, but a few years ago i had to fix a box scarper on a john  deere i added 2 inches of halt inch plate, using flux core 0.35, its still in servise today, i just V groved it when i welded, I also welded 3/4 cleats on to a case 450 dozer's drive sprocket, when the guy got it down a canyon and rolled all the teeth off, a Quick fix to get it up the hill for proper repairs lasted four months and 3 jops later, until the owner could buy new sprockets, again used a V grove weld, as for a solid core wire i run 0.25 wit co2 and weld bumber mounted trailer hitches to 1/4 inch stock, useing 3 passes along each weld, I pull a 32 foot toy box from sacramento Ca, to Sandmountain NV al the time, its never failed me yet, just over a year on the new hitch. anther hint for flux core is to turn the wire speed way down, so the base metel melts more, and if you realy want to play, turn it almost of and feed oxy weld rod into your puddle, try diferant things on scarp to see what you like and what penirats best, for your needs. then practice practice practice.Last edited by bill104; 06-16-2007 at 01:14 AM.
