Question about ARC Welding Tools

Open Question

I'm repair a Lincon 400AS-50 Arc Welding machine, trouble is, start OK, there is no output from either the AC outlet or the welder output studs. However, I have gone through all the test and checks that was downloaded from the troubleshooting guide of Lincoln with the wiring diagram. All my test seems to be all right. I have chabge the flashing diode which was blown before repair, changed and still no sign of voltage...please I need the experts to assist me..thank you, Tim

SOURCE: Problems with welding with a Forney 180 amp. Arc Stick Welder

check your input power connections on the primary side of the welders transformer, then if its an infinite control welder check that control,otherwise if it's a plug- in selectable amperage check these connections,it sounds like the infinite control is getting dirty and not passing all the current it shows on the control, also double your O.C.V. on the secondary and see if its with-in welder specs

Stud welding makes more sense. Our stud welder systems each have a stud gun welder that spot-welds a series of pins onto the surface of the dented metal.

What settings do i use to arc weld.


Not sure what machine you have, but it should be DC straight (electrode negative or DCEN) and DC reverse (electrode positive or DCEP). The polarities have different characteristics. For example, if you're planning to TIG weld, you would either use DCEN or AC (if welding aluminum). For the general stick welding process, DCEP tends to give you a deeper weld. The welding rod you buy will have recommended machine polarity and amperage range settings, you should use the recommended polarity for whichever rod you're using because different rods are designed to weld under different circumstances. But, generally speaking, most welding rods for steel will work on DCEP without much trouble.

Changes between AC and DC voltage at the electrodes.



Q: What Type Of Stick Welder Works Best For All-Around Use?

A: A welder with an AC/DC output, whether its an electric arc machine like Miller\'s Thunderbolt or a gas engine drive like Miller\'s Bobcat.

DC welding offers advantages over AC for most Stick applications, including: easier starts; fewer arc outages and sticking; less spatter/better looking welds; easier vertical up and overhead welding; easier to learn "how to weld" and a smoother arc. DC reverse polarity (electrode positive) provides about 10 percent more penetration at a given amperage than AC, while DC straight polarity (electrode negative) welds thinner metals better.

Q: Does An AC Output Have Any Advantages?

A: Yes, if you need to weld on material that\'s become magnetized from friction, such as when hay, feed or water constantly rub against a steel part. A DC output won\'t work because of "arc blow," where the magnetic field blows the molten filler metal out of the weld puddle. Because an AC output alternates between polarities, it enables you to weld magnetized parts.

Lincoln electric ac/dc arc welder will not arc


Check the dial indicator. Sometimes if someone changes the amps while welding, there will be a break in the coil. It will work at a different setting as long as you are away from the break.

The settings for welding aluminium using a Tig200P AC/DC inverter


If you are using a remote then you would set the machine in standard for controlling output and also to AC output, HF tig, contactor and control in remote position. I don't know if this helps or not but I pulled it from an owners manual.


1/16" (.062) - pre-flow .1 sec., hot start 20, amperage 70, Hz 100, balance 20%, post-flow 6.0 sec.

For pulse settings - set pulse width 60%, peak current 100, background current 30, Hz 1.0

1/8" (.125) - pre-flow .1 sec., hot start 20, amperage 150, Hz 80, balance 20%, post-flow 6.0 sec.

For pulse settings - set pulse width 60%, peak current 150, background current 50, Hz 1.0

I have an ancient 125 amp AC arc welding machine on which the current is varied by moving the negative lead from to different terminals. However the terminals are in pairs and joined by slotted metal...


Hi:

Since you did not mention here brand or model of welder; I'm pretty sure that your machine it's an AC/DC machine, the series of slotted plates means that the machine will output 50 amps in AC or 80 on DC. 60 in AC or 125 in DC.
If you want to work with lowest amps available, just put the selector on AC and connect your cables to the 50/80 amp side.
You should have a selector lever to switch back and forth from AC to DC in front of the unit.

Hope this work for you.

My tig welder wont arc unless I touch the metal with it


my guess would be the type of welding machine you have.usually there is extra switch which says start control also continious cycle , sometimes smaller machines dont have these switches to allow a wider variety of tweeking the welder ,also its ok if you have to touch the base metal cause thats what starts the contact with the work peice ,keep a arc after touching about 1/4 inch away from work peice ,also a good steady hand rest will make a good welder in any situation this should allow the arc to remaim stable with a comntinious weld arc puddle. happy welding
