:hi, I had a sureweld mono mig which worked ok in uk .Sent it to my brother in Estonia but we found it did not weld as good there.. it just lays the weld on the work.We checked the volts coming from the supply ,it was coming out at 230 to 239. We cleaned the contacter and fitted new mains cable to it.It got a bit better but still just lays the weld on the top. We butt welded some flat steel together and we tried to break the weld and it would not break, but still geting no penetration. can you help?
