I have a Craftsman Stick Welder mod. 113.20245

It does say it is primarily a TIG welder. My guess is the the sticks are too heavy gauge for it. Did you get a manual with it?

That depends on whether you're able to make the necessary alterations,and if the machine is large enough to handle stick welding currents.

wrong
gasless mig welders are used the same as gas /wire migs
the only difference is the polarity of the leads to the hand piece and the work ground and this is indicated by the plug in the machine for the ground lead
what the "someone " would have been referring to is the duty cycle of the unit
every welder has a duty cycle because of the heat generated in the welding process by the electronic components and transformers and if that duty cycle is exceeded the machine stops working until it cools down or damages the circuits
it is stated as a % of time in use so a unit with a 20% duty cycle means that for every 20% of use it has to cool for 80% of time
as an example ---if you were using a stick welder, the time taken to burn the stick would be 20% and the time taken to insert a new stick and clean the slag off the weld to resume the process would be the 80%
It also depends on the amps being used for the weld
on a machine with 120amps capacity and you were using 15 amps to weld sheet metal--body panels - the length of welding time will be considerable compared to using 115 amps where the weld time would be a few minutes
there are plenty of helpful hints in the operators manual and other technical publications on line

Elmer, If you remove the gun assembly from the machine, if the machine is now not feeding wire, the problem is most likely the gun trigger is faulty. The switch contacts heat up and start sticking over time. If able too disassemble and clean trigger contacts. Check the attached links,instruction and guides, Good luck

commin problem with wire feed welder
Wire won stop feeding

The Rossi 220bz mig welder comes set up to use gas welding, that is with the Mig electrode connected to the positive terminal, inside the machine.
To use gasless mig wleding, the mig wire must be disconnected from the positive terminal inside the machine and reconnected to the Negative terminal - inside the machine. Open both the side coveres of the welder using a phillips screwdriver. Use a 13mm spanner to undo the hex nut holding the thick copper Mig lead to the terminal named positive, then lead it through the machine to the terminal on the oppisite side of the machine, labelled negative and screw it in place there with a 13mm hex screw. Be carefull not to bump any of the many electric parts inside the machine.
If you run the Mig welder in gasless mode with positive earth and positive elecrode it will blow the household electric fuse.
If you run the Mig welder in gasless mode with negative earth and positive electrode it will work, but the end of the Mig gun tip will get very very hot and start smoking abnormally from excessive heat.
But if you take the side covers off and rewire it (takes about 10 minutes) to negative Mig Electrode, the Mig gun tip remains cool and does not overheat. You will have to cut just one white cable tie, to get an extra inch or so of free Mig cable, so the thick copper Mig lead will reach accross to the terminal on the other side of the machine named negative. Stick the earth lead at the front in the positive terminal.
I did this on my Rossi 220bz mig welder.

Hi:
Your machine overloaded and the Fuse F1 must be open, just change it. Here's the link to the owner's manual:

Check section 6-4 for more details. ' Good Luck!

you have to use the gas 75-25 for steel and cast iron 100% argon for welding alumanuan

I bought a good working Lincoln 225 about 2 years ago with the extended leads for $ 35.00 at a garage sale

.04 tips with .04wire with .04 liner etc.........
.025 tips wire .025 wire with .024 liner etc.....

I think most of the older Craftsman welders were made by Century which is now owned by Lincoln Electric Company. If this is a wire feed welder you adjust the wire feed speed so that the arc sounds like eggs frying, the voltage setting (if any) will depend on the thickness of the material you're trying to weld. If it's a stick welder there will just be a current range control that you set depending on the thickness and type of material you're welding.

Rank me if this helped,
