Would like to know how leads hook up


for normal wire on gas the + wire is the hand electrode
the - terminal ( clamp )goes to earth on the job
when using gas-less wire in a mig the wires are connected in reverse
when using a stick hand piece in the mig the stick hand piece is on the + terminal , the same as gas less wire
all of this would be in your user hand book or can be down loaded for your machine

I have a mastercraft arc welder that turns on but won't arc the overload light is not on or enything


I'm not familiar with this model and I don't know it's age, but as a general check item on any welder, make sure your welding leads are in good shape and that your earth clamp is actually connecting to it's lead. They can burn and tarnish with use and fail to connect. Check likewise the lead connection into the electrode holder. Check their attachment to the welder unit too. There may be a thermal overload protection fuse/device/switch inside the unit which may need to be reset/replaced if you've worked it heavily recently.
If the welder is TOTALLY silent when you switch it on, it may indicate a transformer failure for some reason, usually there is a little bit of buzz or hum. Within safe limits (bear in mind there are dangerous high voltages inside the welder) you might use a simple multi-meter to check that you are getting transmission of power from A to B throughout the unit to the work piece, and that you've got adequate voltage arriving at the work. More safely, with input power totally switched off and unplugged, you can use a multi-meter to check continuity of circuits through the welder to make sure there isn't a break in connection somewhere from a component fault or failure.

Welder is not sending strong arc


maybe its your volts too. make sure you are grounded properly and clean from debri's, strike the electrode like a match and keep the arc close to your work-piece. dont go too fast and make sure your not wearing to strong of a lens in your hood. gold lens number 10 are the best for 7018 rods.

Some proplems face in welding aluminum


Are you asking about what the problems would be? First for mig welder, you can't push small aluminum wire through a very long cable. You need a teflon liner for it to work at all. A spool gun works better. Be sure to use correct gas for aluminum. Usually 100%argon, but some people use Argon/helium or helium. Use direct current reverse polarity (electrode positive) from constant voltage (CV) power supplies. If shallow penetration is required (i.e. for weld surfacing and cladding) straight polarity (electrode negative) can be used

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

Not forming a continuous bead on the inside of a 3'' carbon steel. set amps at 85/ 90 argon at 10, what am i doing wrong. please help me


I need more info, you are Way too vague.

What type of weld are you trying to do? A Fill weld?

Are you trying to fill a V in-between two pieces of hard steel, (Carbon), that is 3 inches thick?

1. If you are, the electrode should be held at a 90 degree angle to the metal. Straight up, and down.

Moving the electrode too fast will cause a intermittent bead. Slow down. TIG welding takes time. It isn't like ARC welding.
If the electrode burns off to one side, you don't have the electrode in the correct position.

2.Too little heat, (Amperage) will make a 'Cold' weld, and you won't have the penetration that you need. Too much gas (Argon) will do this also. Too little gas, and you'll burn through.

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.

Miller syncrowave 200 makes buzzing noise from spark gaps.


Odd noises other than the normal sound of the spark gap working are often the result of dust and junk inside the case of your welder. That it also bogs down when it gets warmed up (fan comes on), also points to a need for some "annual maintenance" stuff being done.

Completely isolate the machine from the building power supply, pul the plug, open the circuit breaker, do whatever it is that makes the machine have no connection to any power.

Take off the covers with a 10mm or 3/8 inch socket (can't remember which)

Use a shop vac to **** out all of the dust and debris out of the machine. Low pressure (40 psi) air can sometimes be helpful to dislodge caked on dirt. Avoid any metal tools near the capacitor bank inside the welder.

Wipe off the fan blades.

Clean the spark gap electrodes by inserting and removing a matchbook cover, a business card, or a piece of white cardboard several times. Inspect the electrodes and adjust them according to the manual that came with the welder.

Check all of the power wiring connections for tightness by gently tugging on them. Look for signs of overheating on the power connections and on the internal connections to the welding terminals. Check the range switch for heating too.

With the cover still off, reconnect the power and turn the welder on. Look for obviously vibrating laminations on the main input transformer. If you see one buzzing back and forth, or if you notice lots of wear and tear on the varnish coating of the laminations, shut everything down and repair the loose laminations with some anti-fungal high voltage varnish.

Turn the welder off, disconnect the power, and put it all back together. Then turn the power back on and weld something, if htere is still a buzzing noise you'll need a Miller tech to solve the problem, you likely have a bad input transfirmer.

Regards,
Carl

TIG welder help


Choose the electrode to use for the project you are starting as well as the variety of alloys you'll use such as the 6061 Aluminum alloy electrode. Grind the electrode to a point. Try to create a tip and sharpen it to help it become more rounded as you weld. Place the electrode into an electrode holder with the tip about 1/4-inch away from the sheath. Choose the settings on your tig welder. The three main ones are AC, DCEP and DCEN. Choose AC for aluminum. Slide the "cleaning/penetrating" slider more to the penetrating side. Set the "air on" to five seconds and the "max amps" to 250. Turn on the gas. For aluminum, use pure argon. For steel, an argon and carbon dioxide mix. Scrub your welding table or flat piece of sheet metal with a wire brush to make it clean and flat. Gear up in full welding safety gear including hood, goggles, apron and gloves. Hold the electrode in your dominant hand and start your welding project. Check your settings every so often to make sure they haven't changed and adjust as needed.
