Like new Tekton 1/2" drive torque wrench. 25-250 ft-lbs. Part number 24340. I've only used this one once but I'm getting rid of tools I have more than two of to prepare for a move.
Located in West Sacramento - $30 plus shipping or local pick up. PM me for a shipping quote.
If you're welding 1/4" plate with a 120v mig using shielding gas, you better prep the hell out the joint by beveling it and make multiple passes while being mindful of the duty cycle, which at that point would be maxed out.
