OK So ive got a trailer, i went to weld on a new hitch. Switching from 1 7/8 to a 2". I went to weld the new one on and when i go in from underneath upside down it spits and sputters and welds like crap. I even had big chunks of weld down in the gun when i stopped. Here is my welder its a 110 volt lincoln wire feed i am using 75% argon and 25% co2. Its the most argon i can get where i live. When i weld upright everything is fine. do i need a flux core wire? Im not a very good welder by any means but i can lay a decent bead most of the time just not upside down. But rest assure if i can get in this winter i will be taking a welding class at my local tech school. I also have a small stick welder that i cant use because i dont know what im doing.
Thanks in advance to all who can help.
