Welding Table(s)

Anything I need to watch for in a welding table?

I picked up 2 matching cabinets at work today. They have 4 wheels and drawers. They are all metal drawers and tops. One drawer is big enough for my welder to sit in. I might drill a hole in the top for the gun, drill a hole in the back for the plug to come out and just ground it on the drawer. Anything good or bad about this set up?

they were free.

Can it be painted or should I get the paint off the top.

I would take the paint off the top, and weld a tab somewhere to ground to. You don't want to just ground to the drawer, because then the current has to go through the bearing or slides and can arc and possibly ruin them, or possibly welding them in place wherever they are when you strike an arc.

You also need LOTS of airflow for the welder to cool itself. If you contain it in a close space you are going to wear it out faster and your duty cycle will go down because it will take longer for it to cool down.

If you are going to use the drawer, I would cut 6" holes on either side of the cabinet to let air circulate in and out.

Don't forget that with mig welding, you need to ground to the work piece, not the surface like stick welding. Unless you are going to tac weld your project to the table, then you can use a ground point.

I would get a piece of metal grate cover it with a 1/4 plate and put it on top over the cabinets, that way when you cut or weld on it, you won't ruin the cabinets and you have a great ground instead of trying to ground using the cabinets. IME cabinet tops are pretty flimsy and do not like to be hammered or welded on.

Look at the pic again. the top door is not really a drawer. it pulls up and out then slides back in parallel to the cabinet top. So the entire side will be opened up. But I never considered air flow, thanks.

Also I did not no I had to ground to the work piece.

As soon as you strike an arc with the ground clamped to the table, the workpiece will arc to the table. I never have to ground to the piece itself, my clamp is on my table!
I do agree with putting a thicker piece of metal on the top of the cabinet, to strengthen it.

hold on. I must not be understanding. So you clamp to the table and it makes your work piece arc to the table. that does not sound like a good thing

With stick welding, you can do that easily OR tack it to the table but with MIG the best way, and safest, is to clamp to the work.

I was taught both ways and always had better welds with clamping right to the work.

If your work and surface are clean it wont matter where the ground is. I have never had a problem using a grounded table, thats all I use, and thats all we use at school (unless we are building something big that wont fit on a table, or fixing a trailer or whatnot) for MIG, TIG, Stick, and FCAW. For Subarc we tack the piece to the table though, so it doesn't move. Unless its a large piece its usually impractical to clamp straight to it anyway.

Keep in mind if your holding the piece and trying to weld, if you accidentally move it off the table, but your hand/arm/body is touching the table you will get a tingle .

I would much rather ground to my table so I do not have to jack with the clamp, and I have never had any quality issues with my welds due to the grounding point!

I agree with rusty,if at all possible i ground directly to the work peice,i've worked with uncountable fab tables and even on a good clean surfaced 1" or more plate top can cause issues at times when the ground is just permanantly fixed to the table...example:if the peice being worked on is not totaly cleaned of steel scale it WILL effect current of the machine and mess with the amps/heat,causing inconsistent heat from trying to ground through the steel scale,plus like Kettle said about it moving,not only a shock,but if it moves the slightest bit it will cause the arc to break or cause uneven heat/amps in the weld.

Anywhere the ground ends up arcing it will effect you're heat and even cause unwanted scars on a peice ,but it can be easily ground off.

But then again i'm a "picky" weldor when it comes to heat and consistancy when welding,i like it to be smooth and steady.

I think schitzangiggles had a great idea on using some grading and some plate over top of it for those cabinets,it won't be near as heavy as a solid peice of plate but yet just as strong if you at least weld 50% of the plate to grading inside the little squares to keep it from warping from heat.
Personaly i wouldn't go with diamond plate on top like the picture shows though,i'd use plate steel,diamond plate might be aggravating to work with when trying to build something true and flat.

Thanks IW709.

Around here the diamond plate crap is much cheaper than flat plate (go figure) juat flip it over and tack to the grating. The other nice thing about usind the grate is it gives some standoff if (when) you happen to cut through it with a torch/plasma and keeps from catching what is inside your cabinets on fire. I also put a sheet of that Hardie Board tile backer (fiber Cement board) on top of my wood work bench for those times I have to use it to support some over size work, as nothing with a flame will burn through it (all of my benches are the same height).

I don't have any problems clamping my ground to the table as long as I clamp my work piece to the table to get a good current flow.
