As one of the largest manufacturers of plasma cutting, tig/stick, arc welding equipment in the world, Lotos Technology is proud to offer an extensive selection of industrial plasma cutting and tig/stick welding machine with the CT520D. Lotos CT520D is a THREE-IN-ONE Digital Inverter Plasma Cutter (50A) / Tig Welder (200A) / Stick (MMA) welder (180A). You would have to purchase 3 separate machines to do what this ONE machine can do! Using this portable plasma cutter is cheaper than Oxyacetylene after just a few cuts. Less cleaning, less maintenance, less noxious gases, less hazards, simply less overall work and a better, cleaner cut. The torch trigger can be moved for a custom fit. It can be used in finger or thumb positions. The torch head is adjustable for tight spaces. High Frequency DC Plasma cuts thicker materials than standard DC plasma cutters. High Frequency Plasma cut faster with less distortion in the work piece. The Tig welder from this CT520D is clean and strong. This Tig welder is easier to use than any other Tig welder on the planet! An ARC (Stick) welder is a necessity in any industrial shop or home workshop. There are welding jobs that simply require ARC or SMAW (Shielded Metal Arc Welding). With arc welding, no shielding gas is required. Stick welding is cheap and effective: fill the large gaps and holes, weld the cast iron and weld the extra thick steel with the stick. For this Lotos 2011 latest model, we add the aluminum stick welding feature. It is patent pending.

Here are some more information for Welder Stick:
Welder Stick

Underwater welders and those who are qualified to weld , inspect welds, or teach welding overseas in countries like Iraq and Afghanistan generally  make more money than any other welding job. But aside from underwater welding and overseas welding jobs, a skilled welder with his own rig and who can pass any welding test has a better chance of the highest pay. There have even been reports of pipe welders with their own rig making $100 per hour at times.

But not everyone is ready to run their own rig. Some welders just prefer to make a good hourly wage using someone else's materials and equipment without the responsibility and headaches that come with running your own welding business.

For those welders who fall into this category, here is list of the best paying welding jobs:

  • UAW Union Journeyman Tool and Die welders can make up to 30 dollars an hour.
  • Certified union pipe welders with the UA (United Association of pipefitters and plumbers) this includes pipeliner welders (even though they are definitely a different breed) are among the highest paid welders.
  • Certified union  boilermaker welders make a good hourly wage.
  • So do Certified union shipyard welders.
  • Aerospace/Aviation welders who work for an Airline command a good wage ($25-30 per hour plus benefits)

How much  welding jobs pay all depends on demand, location, and how strong the union contracts are. Right to work states tend to pay less.

Some other high paying welding jobs are:

Building and metal trades such as in the Ironworkers, Millwrights, and sheet metal workers. (and even the Carpenters and Electricians have some welders.)

You may have noticed the word "union" sprinkled in an awful lot. There is a good reason for that...It is because some things never change. Union jobs pay better. Plain and simple. If you want to get the highest paying welding jobs, do what you need to to get in the union.  Sure, you may have to travel, work in remote areas, work in rough conditions, and sometimes even around some rough people.

Having said that, its still worth it.

Welder Restoration and the Importance of OCV

The phrase OCV is an acronym for Open Circuit Voltage. It is the unloaded DC voltage that is current at the Weld output terminals of a Welder. This voltage typically averages between 60-90 VDC in Stick (SMAW) mode of operation. The a single exception to this (in which an AC voltage is current) happens when dealing with a Transformer based Stick Welder (frequently called a Buzz box) which has no DC rectification of the transformers secondary voltage. In other modes of operation (Weld processes) such as MIG (GMAW), or TIG (GTAW), the OCV will be various to that specified in Remain mode. The Weld procedure that is selected is centered on the performance of the Welder. Not all Welders are capable of several processes. For instance, simpler Welders have Stay mode of operation only.

When Problems Shooting an SCR (Silicon Controlled Rectifier) primarily based Welder, an OCV measurement offers a beneficial device towards an efficient repair. The initial step in this procedure is to talk to the Welders Support Manual. The Specifications web page will show the Highest OCV for the selected Weld procedure. Report this voltage!

Next, consult the Schematic to reveal the quantity of SCR's in the layout, and the efficient amount of switched existing paths. Report the quantity of present paths! In this situation, a present path is a branch from the Transformers secondary winding, via an SCR (Anode to Cathode), and culminating into a current node prior to filtering by the output Inductor (Reactor). The present node normally has multiple branches feeding into it with one dedicated output.

Utilizing a DVM (Digital Volt Meter) measure the OCV of the Welder. If it is close to the Highest OCV then this signifies that all SCR's are firing (triggered from an applied gating voltage), and would be an ideal circumstance. If not, divide the Maximum OCV by the quantity of switched existing paths. This amount represents the Voltage that each SCR or existing path provides as component of the layout. Subtract this worth from the Highest OCV. If the value (Voltage) equals the Welders measured voltage then one SCR or existing route is faulty. If not, carry on this method for the variety of present paths that are staying utilized.

An illustration of this is a Welder with a Highest OCV of 60V created by synchronously firing three SCR's. The measured OCV from this Welder is only 40V.

60-(60/three) = 40. This would indicate a difficulty with a single of the SCR's or a triggering matter. As you can see, this method is capable of pointing the Fix Technician in the direction of a speedy fault resolution.

Up right up until this point, the measurements that have been used (namely, OCV) occurred with no opening the Welders situation. The following paragraphs refer to part place Useful Analyze procedures. To move forward with this, the elements (SCR's, IGBT's or MOSFET's) must be eliminated from the suspect Welder earlier to carrying out these steps. For security causes, below no circumstances ought to the elements staying tried be electrically connected to any other devices or Power Supplies apart from the Analyze Products becoming applied to determine component defects. If you are not experienced in Electronic Restore, and don't have a solid electric background do not attempt any kind of electric restore on this kind of products. Within a Welder, there are Substantial voltages current that can Kill. This warning is not to be taken lightly! In other words, if you are not a qualified Electronics Technician, Electric/Electronics Engineer, or Electrician then treat this info as reference material only. Refer your restore to competent personnel.

The SCR's must then be individually tried out of circuit utilizing an SCR Tester or Ingredient Analyzer. This sort of Analyze Gear is able of triggering the Gadget-Below-Analyze. A DVM will not. Another essential concern is ESD safety of the SCR throughout this screening phase. Select Check Gear that grounds (or connects) all SCR terminals to the exact same probable whilst completing Useful Test. If there is no possible distinction (voltage as a function of charge) among the SCR's terminals, there is no probable for ESD destruction!

When Problems Shooting an Inverter primarily based Welder, a reduced OCV normally shows a Switching concern with the Welders IGBT's (Insulated Gate Bipolar Transistor), or MOSFET's (Metal Oxide Semiconductor Field Effect Transistor). This is typically induced by a faulty Gate Driver or Handle Board. The two of these issues are solved by means of board replacement, or element level restore.

When the measured OCV is at VDC (and the Welder isn't blowing fuses or Circuit Breakers) the Switching Parts should be tried for features (Out-Of Circuit).

An IGBT & MOSFET Tester or Component Analyzer ought to be employed to execute these tests. As with the SCR Useful Check Method, a DVM can not Gate these products. There are nevertheless some exceptions with MOSFET screening due to the substantial Gate input capacitance in some units. Also, as previously stated: a DVM does not supply any amount of ESD protection for the part even though undergoing Useful Test. If a long lasting, high quality restoration is attempted, ESD safety via good Check Products variety ought to be a main problem.
