Hey Ironworkers;

I'm one of those guilty of using an el-cheapo MIG welder and now that mine has 8+ years of heavy use, it is showing its age. It starts with poor wire feed, like intermittent. The problem is the size of the roll of wire you use. I really like the 9 pound spool, but these are so heavy and the cheep MIGs are poorly setup for this type of load -it can cause poor wire feed. This can really mess up your welds, so beware.

Another cause of crummy welds is slag buildup in the nozzle.-particularly when doing inverted position welding. Sometimes forming a short to the stinger nozzle, causing the thing to become electrically 'hot'. If you weld like I do, you occasionally touch the nozzle to the work, which may cause a temporary short circuit. The globs of steel shorting the nozzle robs your weld of heating current or at least disrupts the uniformity of the gas envelope, and can mess up your welds. . .beware.

So the moral of the story is:

-Keep your MIG stinger clean; use a nozzle protectant such as "spatter-pruf" (avoid silicone gunks and sprays) and regularly pick out the spatter globs that accumulate in the nozzle.

-Prepare weld site and vicinity to bare metal clean as possible.

-Keep on hand spare parts such as nozzles, tips, rollers, and maybe a hoze if you are rich.

Tip: add to your machine a ball bearing setup such as a 'lazy susan' to aid the wire spool in moving freely (in horizontal orientation) as the plastic arrangement will wear out, causing less than smooth feed and rough welds.

For those doing inverted position welding:

-Use your leathers, gloves, skull cap and chaps, or at least cotton jeans and . .socks. Even then molten droplets can sneak in and pock your hide.

-Use a clear protective shield over your hood's viewscreen to protect the shade coating and ensure UV eye protection.

-Keep a fire extinguisher within reach.

-Avoid inhaling welding fumes, thus 'fume fever'.

-Avoid migging in drafty locations (gas or mig).

<do penetrate deeply> =:)

-Do *NOT* use 'weld thru' coatings in vicinity of welds. -for high-current stick welding its probably ok, but for our low-amperage stuff, -it wont work.
