A 110 welder question

[blazer2007]

I have a lincoln 110 wire feed welder with gas but it has the A B C D heat settings.I,m trying to patch some rust on floor boards but if I have it set on C I get good heat on the new metal but get burn threw on the old metal and if I go down a setting I just get a blob sitting on the metal with little penitration.So how can I compensate for this ,more or less wire speed ,hold gun back further ? I seem to do OK on thicker metal but having trouble with this 16 gauge

I'd be interested to know this as well. I was told the Lincoln 110 was not ideal for this kind of work.

One of the things I might try would be to put a "backer" behind the thin metal, similar to when a piece of copper is held behind the material when filling holes.

For each power setting you will have a wire speed for each material and each size of wire. For sheet metal I use .023 wire. When you go down on heat slow the wire speed down. Any time the metal you are trying to welt is thinner than the wire it will burn through. Also when you do thin material you can pulse the trigger to get small sections of weld at a time to help reduce the heat into the material. I use this method using what a lot of folks call stitch welding. Weld a small area and move down a bit and weld another small area. Slowly filling up the areas in between each run of welds.

did you cut the rust back to thicker metal? Good tips there on quick tack welds, move to another area... otherwise too much heat for the thin metal.

i used a 110 flux core welder for most of my truk; mustII x-member down to bed modifications
sheet metal is always tricky for any welding machine
the trick is to tack move an inch and tack, move, tack.
keep moving and tacking eventually everything gets welded.

all my bed mods were with fluxcore 110v lincoln welder

metal cut back good

wire size might be my problem.How important is it to have your brass nozzle and gas shield[at the end of the gun] in good shape?

Check out Frizzel Frie's work if you think a 110V ABCD welder is the wrong tool to use. You will soon have a different opion. And Orgre's (now that I know what he used).

It's not the tool, it's how you swing it. Tack, skip, tack, skip... cool, grind, hammer, grind, hammer. Back to tacking.

Move down to .023 wire. It takes a lot less heat to melt the wire which stop you from ending up with blowthrough. You will have to experiment with temp and wirespeed. .023 is best for sheet metal in any welder. If your nozzle and tip aren't clean then clean them. Tips are cheap and you will need a new one for the .023 wire anyhow. The nozzle can be cleaned off with a pair of wire cutters easily.
