Question about Welding Tools

What electronic part is damaged?

Welding starts when switched on but when you strike the electrode on the surface to be welded, arc starts but stops as soon as you strike the surface. i noticed that the high temperature indicator is on. turned off the machine and restart, the same thing happens.

Does the electrode stick to the metal? In which case your problem is with the elctrode or your method of striking the arc.

SOURCE: My welding machine will not weld?

Hi, put the setting on 150 amps, and see if the welder welds. do you have a gas or electric welder?
some welders have a reset botton in front. tell me how many amps your welder produces.

If this doesn’t work for you please write back. Thanks,

SOURCE: puk 111 welding problem

Mine was doing the same, spoke with the technitions and they told me to undo the connector from the hand piece to the machine at the machine, you then need to disassemble this connector and look to see if one of the white wires is dissconnected, if so you need to carefully push the gold plated pin out the back of the connector towards the cable, solder the wire back on and reassemble and it should work.
If not contact the head office and they were very helpfull.
Cheers Robert

SOURCE: welding machine wont start

there might be a low oil shut down switch that is open, look for it and jump it out, and then try to start it

SOURCE: hey i have a PRO 165AMP AC ARC WELDING MACHINE

Try cleaning the ground ******** both ends and try cleaning the rod holder, if eather has burn marks on it it will not burn, let me know if this does not help. Most tims it's the ground connection.

What polarity do I use for tig welding aluminum, and what color electrode for miller hf-p dial arc


Jackie, watch the linked videos on tigging aluminum. "I hope this helped you out, if so let me know by pressing the helpful button. Check out some of my other posts if you need more tips and info."

Tip

Sharpening electrodes when tig welding in DC


Use the smallest tungsten possible, ie 1/16" welds up to 115amps. Hold the tungsten straight up the face of the grinding wheel so the striations go up the tungsten. This encourages the arc to go straight down the electrode thus avoiding arc wonder on lower amperages. It also helps to make the point as long as possible to encourage a finer arc. Happy welding.

What are 4 common welding processes?


There are four common welding processes utilized through out the work industry today. They are :
(Stick Welding or SMAW) Shield Metal Arc Welding
(Mig Welding or GMAW) Gas Metal Arc Welding
(Tig Welding or TMAW) Tungsten Metal Arc Welding
(FCAW) Flux Cored Arc Welding

There are many many welding processes, however these are the most common. The type I am going to discuss briefly today is SMAW. The most economical and cheapest way to learn if welding is for you or not is to start with stick welding. It has the least amount of variables that can go wrong for a beginner. It is not fast paced like mig or flux core, so you have time to watch the molten puddle to see what it is doing and make necessary adjustments to correct the size, shape, and contour of your weld bead. The hardest part for a beginner is to keep the electrode from sticking to the work piece. Thus is the reason it got the name of "stick welding". There are three common ways to strike an arc in SMAW. Tap Start, Scratch Start, and the last is to place the electrode upon your fingers like a pool cue, and shoot the rod like your playing pool.

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.

If I turn the ac dc switch while what dose it do to the wielder. Now im not getting any juice to wield .thank you


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.

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

Miller S-54D 115V digital wire feeder that does not weld right.


Hi Kevin,
Causes of poor penetration: Travel speed too fast, welding current too low,
poor joint design / and or preparation, electrode diameter too large,
wrong type of electrode, excessively long arc length.
Solutions: Decrease travel speed, increase welding current, increase root
opening or decrease rootface, use smaller electrode, use electrode with deeper
penetration characteristics, reduce arc length.

I have a problem with **** inclusion in my welds. I am using 3/32 6013 electrodes on a small AC unit. I am welding 1/8 inch mild steel plates in a 2F configuration. When I start the weld I produce is...


A number of things can cause "****" inclusions, poor Technique, bad fit up, Amperage too low, Electrodes damp---etc. Firstly you are using AC-- Check the Electrode carton for the correct ampage, then check the set up, this is the electrode use AC or DC, most 6013 work better on AC terminal setting dont matter + or -- earth.
If you weave too wide you will loose the fluidity on the weld metal, meaning you will be welding over the ****.
before welding the bead, start and iniciate the weld pause a second until the arc is established then move off.

Plasma cutters problem


Depending upon the design of the torch (e.g., orifice diameter), electrode design, gas type and velocities, and the current levels, several variations of the plasma process are achievable, including: * Plasma Arc Welding (PAW) * Plasma Arc Cutting (PAC) * Plasma Arc Gouging * Plasma Arc Surfacing * Plasma Arc Spraying
