Here's my MIG. I know it's not much but it was my Dad's. I'm new to welding and need to weld frame rails and torque boxes on my 68 Mustang. The steel is probably less than 1/8" but I can't seem to get any penetration. I'm using .023 wire (AWS A5.18 ER70S-6) with shielding gas and all I can seem to do is tack the heavy sheets together. I am having to weld upside down so gravity is not helping the puddle to form and flow.
Am I expecting too much from this welder or is it me?
