    Looking at doing some body panel replacement was wondering if anybody has recommendations for a good spot welder. I have a Lincoln 110 V wire feed that I’ve used before to do a series of plugs welds. Would preferred to use a spot welder if space permits and wire feed if necessary.
    Thanks for any suggestions

        I have put on many full quarters with a hand held spot welder from harbor freight.

          Thanks
          I will start looking. Is there any trick to aligning the electrodes to each other?
          I would guess good clean metal and a good eye. How does it work with weld through primer?

          I purchased the 220 volt Harbor Freight spot welder and it did well. I had a problem with the switch early on and they replaced the spot welder. The key to success is clean metal and practice on some scrap.
          Good luck.

            They're cheap, but you get what you pay for.

            yep I spot welded two pieces then clamped one end in a bench vise & the other end to my hydraulic puller. It took a couple of times to get the right weld for a really good hold. What I mean is how long to hold the electrodes together & how tight. If that makes sense. Do some test panels. The only places I couldn't use it was the door jambs & rear sail panel. For the wheel wells I had to buy other electrodes & cut them shorter. Just like any other welding all 4 sides have to be very clean.

            You used a harbor freight unit and changed the electrodes to a sorter set.
            Where did you purchase the short electrodes?
            Thanks for your input.

            I borrowed a Miller 220v hand held spot welder last summer to weld quite a few panels on a dart at work. Worked really well and the welds are strong and look factory. I liked it so much I bought the identical one. $2000cdn from the local miller dealer.

            I have the old school turquoise greenish blue Leno panel spotter as pictured originally in the first couple of posts along with a Miller 18" tongs spot welder. They are both probably 25 or 30 years old and still work great. I bought them used and have had them almost that long..

              The new Lenco 4000 Is rated for 20 gauge automotive steel max. You guys say you had no problems? I would think it wouldn’t work welding 2 pieces of 18 gauge?
