Used Arc Welder...

Hi everybody,

Recently, I was given a used Arc Welder from friends of mine. They thought I might be able to get some use out of it. Well, it has been about 4 years since I've done any Arc Welding. Needless to say, I'm going to be a bit rusty. I have all the literature from the class I took at the Community College, so I think I'll be okay.

What I'm wary about is the condition of the Welder and the electricity. This welder has a couple of areas where there is black electrical tape wrapped around some cord, and wondered if this is something I can have replaced and if it is going to be costly. The clamp for the electrode seems a bit melted, but I'm not sure if this something I should really be worried about.

The last is the electrical currant needed to run the welder...it needs 225 AMPS, which I know is standard for this welder. Is it possible to have an outlet installed in my garage (I won't be welding in there), so that I can run the leads to the yard to work on small projects.

I thought this would be good for small projects that won't require strong structure. I though of making some small sculptures and some small jewelry stands. I've got the gear needed for Arc Welding....I don't have a MIG welder otherwise that would be my first choice.

What should I do? Please check out the photos and let me know what you think. ;-)

Cheers!

Welder

Hi Jamie,
Some of the things mentioned may be only cosmetic, but it good to be sure.

The 225 amp is output from the welder, but less than 50 amp at the input. For small jobs you may not reach that load, so a 50 amp outlet from the power panel will be enough. You may need a longer power cord to reach outside.

The next thing is lots of practice. Hope this helps.

Thanks Don,
I appreciate the info on this. I'll see what I can do! ;-)

Tape on Cord

Hi Jamie,
The cord with tape on it should be replaced. I would at least remove all the funky tape and redo the repair with some fresh tape.Have fun.

Arc Welder cables

Jamie, You should remove the tape from the cables and inspect for damage to the copper, if it is damaged you should have it repaired and taped up securely. Or replace the cables. This could be causing the overheating and melting you have observed.
As for the 220 volts outlet, you could run a 220 extendsion cord from you kitchen oven to the yard, but do not try to operate the stove and weld at the same time. Your cloths dryer is 220v also but usually only 30 amp. (this is not a good idea). You should have atleast 50 amp breaker.
Best wishes,
Stephen Kishel

Thanks Stephen, Thanks for

Thanks Stephen,

Thanks for the info on the electrical part...last winter I had to go without a heater in the house and overloaded the circuit (not thinking) with a portable heater and the fan on the fireplace going at the same time and well, we had a problem...LOL! Thanks for reminding me!

Jamie, Ah, the venerable

Jamie,

Ah, the venerable Lincoln tombstone buzzbox - one of the most reliable welders ever built. It iwll do fine for most of what you want to do.

The burning on the stinger (rod holder) is nothing to worry about, just happens when you run the rod too short. Should last another twenty years or more. The tape one the ground clamp is something I'd pull off and make sure the cable isn't frayed. If it is, just cut it off and re-connect to the clamp.

The tape on the leads should be pulled off and the cables checked for fraying or breaks. If you find any, get some splice ferrules from your welding supplier and splice the frayed spots. If the fraying is very minor, I'd just re-tape it and not worry too much - it would only have an effect at the highest current settings which you'll probably never use anyway.

You'll need a minimum of 30 amps service to run that welder. 50 would give you room for more extension cord length, but you can definitely get by on 30 if you don't try to run a long extension cord. If you do use an extension cord, make sure you use at least 8 gauge for a run under 50 feet and 6 gauge if you go over 50 feet but under a hundred feet.

You'll want to get some rod that is suitable for the work you're going to do and for AC use. I'd suggest 6011 rod for a good all-around rod that will allow you work out of position if you need and cut through rust and scale, too. Don't get anything bigger than 1/8" rod to start with. The box will burn 3/16" rod, but you only need that for really heavy work and it will give you problems on medium sized work. If you're going to be only doing mostly flat welds, you can get 6013 AC rod that will give you a very smooth weld bead and is easy to run. It is no good for out of position work, however, as it is a slow-freeze rod. The 6011 is a fast-freeze rod and doesn't make as pretty of welds, but is better penetrating and works in all positions.

Enjoy your new welder - it will do yeoman duty for you, believe me. The Lincoln buzzbox has been around for fifty years and run a million miles of welds just perfectly. In fact, I found a Lincoln AC/DC tombstone (named for the shape of the box) in the dumpster three days ago. It looked like it had literally fallen off the back of a truck going down the highway! The case was in three pieces, the innards were flopping around loose, the leads had been cut off and one knob was missing.

I brought it home, banged out the dents, welded the case together, JB-welded the broken rotary amp switch base, installed new leads, re-assembled it and it works like a new unit. Total cost, $75.00 for 26 feet of new leads and four hours time. I had a ground clamp and stinger in the spare parts stash and I'll make a new knob for the AC/DC rotary switch. That welder new sells for almost $700 here on the island. I don't really need another stick welder, so I'll probably give it away to someone who can use it. I just hate to see something that can be fixed get tossed in the landfill.

Hey Rich, Thanks for all

Hey Rich,

Thanks for all this valuable info! I wasn't sure if I should accept this gift...only 'cause they didn't know what they were giving away-not welders! And I didn't know if it was something that could be fixed easily and for minimal expense. Sometimes it's just better to buy a new one, but in this case I'll take your advice on it and see if we can get this beauty fired up! I'm excited about it and have been wanting to get back into welding for some time now. I love jewelry, but I've got the itch to do something a little bigger in scale. I thought jewelry stands were a good place to start!

Thanks again!

I'll keep you posted on what happens next...

I would suggest having

I would suggest having someone with electrial knowledge look at your breaker panel and see if there is room for a 50 amp breaker. If so, run wires to a conviently located outlet box. If there is a plug on the welder, the box would match that. Maybe if you need to replace the dsmaged cord with something new and longer, it would be good to have new connectors for better reliability. Old connectors can get hot and burn.
Your plan to weld outside is good. Many insurace companies will not cover inside welding.

Hey thanks Don, I will

Hey thanks Don,

I will definitely consult someone with electrical knowledge, and I'll be looking into getting a welding curtain to place around me.

Thanks!

Jamie, A welding curtain is

Jamie,

A welding curtain is a good thing to have if you're going to be welding where passersby might get inadvertently exposed to arc flash. Keep in mind though, a welding curtain can also act as a windbreak, which is a two-edged sword. On the one hand it can help with vagrant breezes that may cause poor welds due to blowing the shielding gas away (more of an issue with MIG and TIG than with stick), and on the other hand it can trap the fumes from welding, resulting in an unhealthy atmosphere for the weldor. Things to consider.

When/if you set up a dedicated circuit for that welder, be sure that the wire and breaker you use are compatible, that is, don't try to use #10 wire on a 50 amp breaker. #10 can carry only 30 amps at 110 volts and if run on a 50 amp breaker it would melt before the breaker tripped. It's okay to use a breaker that is under-rated for the wire, but never use wire that is under-rated for the breaker it is on. If you do a Google search for "ampacity charts" you'll find charts showing what gauge wire can handle what amperage load at given voltages and distances.

Enjoy your new toy - errr, tool.
