Hi all, I've been after a used arc welder, and a Cebora 210 dual voltage has come up for reasonable money. I have been using my Cebora Boxer mig for odd jobs, but found that I wasn't getting enough penetration when I tried welding a bracket to my trailer. What's the consensus of opinion on used arc welders. Do I just need to avoid and invest in an inverter? Any help much appreciated!
