Greeting, I'm doing a patch on my truck frame. Welding store recommended upt612. What do you thing 140st at 60 amps dc+. My patch will be 5/32 cold roll. I want to do a vertical pass on each side and call it a day. What do you guy's and gal's think.

[MinnesotaDave]

I wonder why they recommended a 6013 rod?

What size did you buy?

[AKweldshop]

I'd recommend a 3/32" 7018 at 90amps DC+.

6013 on a frame is like an accident looking for a place to happen. The guy at your LWS is an idiot

Buy a handful of 3/32" 7018. You'll be glad you did.

[Timothysvec]

Thank you for the quick replies. 3/32 is the dia. On the upt612. Also if you mouse over the pic, you can see what I am up against. I'll be cleaning up everything before the patch. It's only one spot on my truck. But super rusty. Ok 7018

[AKweldshop]

Yeah,
You might try 80amps.
About 45deg uphill push, and move the rod straight up the joint.
That's how I'd do it anyway.

Let us know how it turns out.

I will, it'll be two week's before I'm ready to burn...... But will keep you'll posted . Thank's again for the advice.

Ok, I have made my patch. 1/8 black generic steel. Am practicing up hill verticle and will be prepping the truck frame on my next day off. My question is, do I have to do anything in regard's to my 94 gmc, to protect it from the weldng process. Battery, computer ect. I will have a fire extinguisher.

[Otto Nobedder]

Yeah, you should disconnect the battery. In a '94, that should be sufficient. '94 GMC, will still have an OBD1 system, so the battery should be all you need to unhook.

Steves right anytime u weld on a vehicle disconnect the battery or u can fry computers or wiring. As far as the welding goes I second the 7018 i like Lincoln rods myself. Id turn the dig up if u have that function an just weld it vertical...Id do it with a 90° rod angle myself...but its ur choice to make

[79jasper]

Not only disconnect battery (side note: negative should be first off, last back on)
But also ground to the piece you're working on.

Forget the 6010.
I would follow the instructions on disconnecting the battery and I would use 7018 between 75- 85 amps.
I would practice weld a sample of the material You plan on using as a Patch , before the actual weld.
