Also thread bump: my wire speed was perfect. Heat felt perfect. Clean material. Clean ground. BUT once I got to the second side it felt like the wire was getting jammed or wasn’t coming out smoothly. The feed wasn’t kinked or anything weird. Tip was as clean as normal. Any ideas? Maybe duty cycle? It wasn’t running long welds but the welder was on while I was prepping. Has a brand new spool motor as a piece broke cause some retard (me) pried on the wire guide and broke a piece that Lincoln doesn’t sell alone. (Power mig mp210)
You can tell in the unpainted pic the weld on the left is inconsistent and than its smooth it was acting up and than the wire came out just fine.
A lot has to do with gun position as it pertains to the shape of the hose.
Often times most don't pay attention to the shape of the hose when welding in different positions. As straight as possible is best.
Keep feed roller as clean as possible.
And most machines I have come across have the feed tension set way too high.
The lower the better to avoid bird nesting the wire, as well as it will teach you to pay attention to your hose configuration.
Vertical uphill I typically leave the heat at the normal setting for that thickness material for a flat fillet weld, but increase wire feed speed and increase travel speed. Helps keep the puddle from running.
Overhead welds I go a little faster in both wfs and travel speed.
If you hit your duty cycle, either the machine will not weld, or every function will drop off dramatically (depends on machine).
