Over built welding cart

admin

This is my second project with my mig welder. The first project I did was a fire wood rack for my parents cabin. After that I was tired of dragging the welder in and out everyday and all the tools, chop saw, etc. So today I started my cart for my miller 180. Its a little over built but the steel I got for free so thats what I used. I will get more pictures once I get some more angle from work. Here's some pictures, let me know what you think. Laying it all out. Getting is square.For some reason I can not get my chop saw to cut good 45* so this is what I get.Front and back all tacked upBottom shelf welded up 1/8" sheet.Here are some weld shots. .030" Wire C25 20CFH Here is the bottom where the chop saw and tank are going to sit.Hope you like.
Reply:design looks good.Sometimes if your down pressure on your chop saw is high, it can deflect the blade a little sometimes.  Also check that your machine is accurate at 45.just a question, are those weld beads run constant or a series of spots?The second bead looks like a series of spots.
Reply:Yeah, chop saws suck at cutting accurate 45's.  They're usually 'in the ballpark' when set up accurately, but never perfect.  If the 45 side isn't off, then the 90 side is.  That's why I got a steel cutting miter saw for doing miter cuts with.  It cuts accurate, repeatable miters every time.   I wanted a horizontal mitering band saw, but space and money didn't allow that so the miter saw was the next best thing.  Evolution Rage 3.www.evolutiononlineshop.comLast edited by DesertRider33; 09-27-2009 at 08:15 PM.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op

Reply:Cart is looking good, but your welds look like spot welds. The crater in the center and the fact they are not tied together gives it away. Work on your weave and you won't have problems with penetration as you will with spot welds on thick material.http://jackalopefab.com/MM210Synchrowave 200DXMiller XMT350 w/60series feederMiller Bobcat 250 with SGA 100 and spoolgunHTP PlasmaFull Machine shop with everything
Reply:I will look into that miter saw. That looks like a better option than the chop saw i am using. Yes those are sopt welds. I need to learn how to weave better. Thanks for all the comments. Keep them coming I need some criticism

Reply:First mistake, you decided to build a cart.  Second, you actually started the cart.  And third/worst mistake, you posted pics of the cart and encouraged criticism of your talents on this forum!    Seriously, looks like a good project and a feeling of satisfaction when done.  Keep the pics coming as project progresses.  By the way, welcome to the forum!  A few of my toys !LinuxMintManjaroMiller Roughneck 2E Lincoln WeldPak 100HTP MTS 160 Chicago Electric 80amp Inverter   Victor O/A
Reply:Oh trust me I am part of many other forums and I know what goes on. I will get more pictures up when I get more steel. Thanks guys.
Reply:Also tell us where you got free steel
Reply:Lookin good...  definitely practice the weave as it will come in handy when filling the fit up gap in your corners.  On a side note, cutting a 43° or 44° angle will give you a small fit up gap.  This is ideal, as a tight fit with no gap will cause a convex weld that protrudes from the corner of the joint.  With a small gap and the right wire feed speed, you will be able to weld the gap and have a more defined joint with less grinding.  You actually cut a good joint without trying, as the inside of the joint touches to maintain dimension, yet the outside is gapped for easy welding and clean up.Last edited by dhillis; 09-29-2009 at 12:50 PM.Danwww.hillisfabrication.com

Reply:Instead of using spot and go, keep trigger held and move. Those spots are certainly large enough you not need to weave. As for the chop saw, ya be clamping angle iron, small surface on front of vise, large surface on rear. When clamped it twists the angle iron. Thus the non 90 degree edge. try overlapping two pieces of angle in the vise to from a box. Should hold the angle iron straighter.
