Welders

As of 2023, welders in Jamaica typically earn between JMD 60,000 to JMD 150,000 per month, depending on their experience, skill level, and the industry they work in. Entry-level welders may start on the lower end of this scale, while those with specialized skills or certifications can earn higher wages. Additionally, factors such as location and the demand for welding services can also influence earnings.

can weld aluminium with a mig or tig welder

A TCU4a weld is a Corner Jount (TC), Unlimited Thickness Full Joint Penetration (U), Single Bevel Groove (4), and (a) is the welding process.

maybe 10 amperes

I have been a welder for over 11 years. For the last 6 years I have been an aluminum tig welder exclusively. A good tig welder can expect to earn $20-30/ hr. A good entry level salary would be $12-18/ hr. There are some positions, such as the aerospace industry that may pay a lot more, and conversely, there are small fabrication shops that pay a little less. The small Fab shops are a great place to learn the skill due to the wide variety of work they perform. After a few years in a Fab shop, you'll be ready to move on to the higher paying jobs.

They have to go to school a long time but there are a lot of breaks. The new students can't hold their breath very long.

The first welder is John Doe.

Welders wear hoods that has a lenses in them that protect there eye's from any harm includeing UV trust me im a welder

in a laboratory

The life expectancy of a welder is their exsperince, faith & way of life. No job takes life faster than others, god determines this only. You can be the safest welder in the world but, a tree could still be blown by the wind which falls right on the safest!

That depends. Tubing as thin-walled as in nice bikes can't be bought from a regular hardware store, you'd have trouble finding even nice Cr-Mo steel there.

Your best bet for building a decent bike is to buy a tube set specifically intended for bicycle frames from an online vendor.

You might be able to find something half way decent from someone selling tubing for roll cages and one-off race cars - but that would still leave you with the issue of head tube, seat tube, steerer tube and bottom bracket having to be of very specific dimensions if you want to be able to use stock bicycle components in the final assembly.

Pretty much the only way around not having to buy a tube set is to buy another bike, cut it apart and use it as a donor for bottom bracket, head tube and seat tube.

I've built an experimental bike once using conduit pipe for the frame, it's thick enough to be welded with a wire-feed arc welder (forget about stick!) but it's really a poor material and not well suited for a serious bike.

If you go for a tube kit, which I strongly recommend, I'd also recommend you to go for brazing rather than welding. It'll add less thermal stress to the seams and give you a better shot at a good result. Besides, such a frame can be taken apart and corrected if it should end up lopsided.

You have the choice between a lugged frame and a fillet brazed frame. IMO fillet brazing is a bigger testament to builder's skills, while lugs leave more room for artistic decorations. Lugs also helps hold the frame together during fabrication, which can help avoid warping of the frame.

If you really insist on actually welding, then TIG would be my first choice.

Yes it can. I use flux core wire because there is no need for gas with flux wire.

its part of the engine but works in conjunction with the PC board.

Don't know exactly what you are asking. Most MIG welders can be used for flux cored, or bare wire. Polarity doesn't change, same for both.

incorrect bare wire with gas and flux cored run different polarity i think what hes asking is how do you change polarity if there is no switch and the answer is usually on most welders in the wire spool compartment there are 2 lugs one with a ground wire and the other with a jumper wire to the wire feeds drive roll assembly. to switch the polariy just reverse the connections on the lugs.

Is this a gasoline or diesel powered unit? If so the lag time between striking an arc and establishing an arc makes it difficult to use for TIG. If not, any DC supply can be set up for TIG. Not for aluminum... Check with your welding supplier.

That may be a difficult item to find. Try joining a welders discussion forum. Welders are resourceful and knowledgeable in their craft.

For output, either one. Most machines produce Direct Current DC. It is much easier to use and most electrodes can be used with DC. Almost all use Alternating Current AC for a power source - input. Hope this helps.

You can rent these machines at a welding supply company as Airgas or Modern Supply. Sometimes PVC pipe outlets or rubber and plastic distributors will have them.

MIG Small machine like Lincoln SP 135 is nice.

If the feed is too fast it will push your hand away from the work. If the feed is too slow the wire will burn back to the tip.

Set your wire speed to your voltage setting by ear. When you hear the sound of bacon sizzling in the pan you are set. If you hear a lot of popping the speed is to fast. If it is to slow you will have trouble keeping the arc going. If you are welding at 23 volts start with a wire speed of about 140 IPM (Inches Per Minute). That's ball park, since every machine and every person is different.

That depends on the diameter of your rod which depends on the thickness of the material you are welding. An e-7018 1/16" rod start at about 70 amps. A 3/32 rod start about 90 amps. A 1/8 rod start at about 110 amps. These are ball park ranges and you will need to adjust to suit. When the scale from your test beads chips off easily you are exactly where you need to be with the heat.

Most welders have a serial number and date of manufacture stamped on the name plate. It should be on the front or the rear of the machine.
