Weld Table Rust?

[dieselscout80]

It seems to be the wire speed as the issue, I only have .030" wire and the tables on the door only cover .030" and .035" wire but if you went down to .023" or .025" wire that would increase the speed so I think you'd be in better shape. I have monkeyed with the settings from recommended by increasing the speed to just over 100in/min and dropped the voltage a touch and it welded better, would just take some playing with settings... If you understand what is going on and are aware of it I'm sure it's something that can be overcome, the welders are solid units and weld very smooth. The gun on my 170 has a switch issue I haven't dug into too far yet but I got that thing in an open box sale for like $125 so I've taken to trying to break it kinda, it's been ran on a 4000 watt generator to the point of stalling the generator several times, used in the sand dunes camping fixing wheeling rigs several times, only issue I've had is the trigger recently...

Thanks

I guess if I can keep my old Craftsman 120 volt / 140 amp mig until I got it figured out.

My old weld duty cycle only 20% and that’s a pain to deal with.

Has it ever cut off from thermal overload? I've given zero care about duty cycle on any welder I've ran... sure I've thought about it but haven't acted on it

It's hard to beat an old transformer unit unless you have to drag it around since they're bigger and heavier... If you don't need to be more portable I'm not sure there's much of a difference if it still works...

Yes it shuts off due to thermal and have to wait for it to cool down and start again.

Running mostly 5 cylinder manifolds at work is similar because all cylinders will equalize.

If a cylinder could talk as some I come across date from the early 1900’s

I’ve posted before the picture of a Linde medical Oxygen Cylinder dated 1930’s with ******** imprint… maybe on a U-Boot or Africa Core?

When cylinders no longer hydro they make awesome wind chimes.

They also make excellent bowling ball cannons that I won't allude to on here...lol

I'll keep my old transformer style Ben Parsons 160amp unit. It's never cut out due to any "heat/duty cycle", and I've ran it hard sometimes. I never could get .023" wire to work. It wouldn't feed and would just turn into a wire ball. .030" works well for everything I've welded up (body work too).

Since I was welding some dumb thin stuff yesterday (pull start housing for a 10hp Briggs) I looked at the chart and had to play with the settings and there's settings for .025" wire and those speeds should feed fine

You might consider a light coat of WD-40. It is not a lubricant, its purpose is water displacement. In addition to spray cans you can purchase it by the gallon.

From the WD-40 website:
"WD-40 Multi-Use Product protects metal from rust and corrosion, penetrates stuck parts, displaces moisture and lubricates almost anything. WD-40 Multi-Use Product 5-Gallon Pail is best used for heavy duty industrial jobs uses that require repeated treatment."

I mean, you can always let it surface rust a little and just take a flapper wheel on your angle grinder to it once or twice a year to clean it up. A damp rag of WD40 should hold it off for a while tho. But some of you guys sound like you keep yours slathered in oily carcinogens, lol.

The original WD40 waxy-film is non-conductive when dry. That's why it works so well drying off wet spark plug wires.

That's a good point. It'll keep the rust dampened but then you may not have good conduction.
