I was doing a welding repair that involved laying a lot of beads. I was using 3.2mm bohler fox ohv rods on my Thermal Arc inverter DCEP set at 120a. I was getting really nice beads, even some peelers!
I had some long runs to do so I brought out my box of Murex Vodex, the longer rod would mean less breaks. But try as I might I couldn't get them to run nicely. They were a pig to get started & every bead I tried had slag inclusions! I tried the amps up & down but no different.
It's not damp rods, the vodex are kept in the hotpress. The box of bohlers has been laying in a damp garage for months & they were ok.
I can only put it down to needing to use a different technique. It has been a few years since I used the vodex & I think I struggled last time I used them, can anyone advise me what method works best? Do they run better on AC, I can use my oil cooled welder for them?
