welding help
i am trying to weld recovery loops to the hitch off my xj. the problem is i can not get the weld to penetrate the hitch nor the loops? i tried preheating and that did not help. the welder is a hobart 140 mig useing 75/25 gas. i am no "expert" welder by any means. i worked at an exhaust shop about 5 years ago, so i know my way around a mig welder but this welder is new to me. i also do minor fab stuff here and there. so anyway, any help or advise would be appreciated. and before i get flammed, i know recovery points is a touchy subject with some and i get it, but i am looking for welding help not recovery point advise. thank you

1. Make sure you have a very good ground, free of rust, dirt and paint.
2. Keep a tight tip to work distant 1/4" to 3/8" is normal. Sometimes 1/16" is required for these low power Migs.
3. Turn your feed speed/amps down and volts up for a well penetrated weld with a shallow weld bead.
4. A drag or pull gun technique will give you a bit more penetration and a narrower bead. A push gun technique will give you a bit less penetration, and a wider bead
5. Remember you are using a Low powered welder. The welds will be small and multiple passes may be required.
Also, you may want to consider changing to Flux core or Flux core with Co2 gas. That Combo will give you maximum penetration out of your welding rig.
Co2 will be cheaper than your 75/25 mix as well.
Good luck
