BRIEF INTRODUCTION

Power drills are one of the conventional tool types that are often found in any industrial workshops or even in the household. They are common tools for sheet metal fabrications or repairs, woodworking, and electrical and general household applications. The applications of power drills start from affixing fasteners to cutting sheet metals.

Before power drills come into the market the drills used are powered manually by operator force. In order to operate them, the force was applied axially on the drill and it was a kind of hectic task for tool users. They are even used for drilling metal types and yet not effective as power drill types. The efficient drilling tool for large-scale productions was made more complicated those days.

The traditional tool types used in past include tools such as Eggbeater hand drill, Breast drill, brace drill, crank drill, etc. It’s rare to find these with the high-tech tools in the market now.

On the other hand, the evolution of power drill types made it more efficient and no need to apply force manually as they are operating either electrical or pneumatic sources. Nowadays these tools are equipped with customized accessories that enable them to use as versatile tools in many engineering applications.

POWER DRILLS TYPES

Currently, different power drill types in the market are customized per application in different industries. But generally, all the power drills are falling under one of these types mentioned below.

Standard Electric Drills
Pneumatic Drills.
Heavy Duty Drills.

STANDARD ELECTRIC DRILLS

These are multitasking tools that are falling under power drills with high portability and easy handling. They do not need physical exertion to operate like traditional drills. Standard Drills are divided into cordless and corded types depending on the power source. The corded types need to plug into an electrical supply unit and it does limit the distance but you can use an extension for quite a distance use. When it comes to working for long periods or with higher power requirements corded types are the best ones. The most standard drill types are in the range of 500-1000 wattage and if the wattage is higher, it works less compared to other ones.

The cordless is portable and powered by batteries. The battery types used for cordless drill types are NiCad, NiMH, and Li-Ion. Normally Li-Ion Batteries give more power and endurance than prevailing NiCad and NiMH batteries used in battery-powered drills.

HIGH TECH TOOLS

The following types of high-tech tools are commonly used in welding, sheet metal, and soldering applications.

WELDER (WELDING MACHINE)

Welding machines (Welder) are the primary tool type that is used in all arc welding processes. It outputs adequate power (either AC or DC) to the welding electrode thus providing the best welding arc characteristics with maximum efficiency. It is necessary to choose the best welder for your welding applications unless the quality welded part cannot be obtained.

The welder types are found in either DC or AC power output. Normally AC power is used for higher temperature ranges, position welding, and mainly aluminum welding. The welding quality of AC types is not optimal as the delivery of heat varies with current variations. These AC machines are widely used as it is cost-effective and do better welding at positions or points. On the other hand, DC machines give you a smooth welding experience as they give a constant current allowing you to have homogeneous chords with high welding stability. Not only that DC machines provide you the adaptability in different welding processes such as TIG or Argon. When buying a welding machine, it is always good to go with DC comparing the above discussion.

The output of welding machines normally ranges from 5-1500 ampere and volts 10-40. Based on power output type, polarity, and function the welding machines are classified into different types such as Welding Transformer (AC type), Welding thyristor, Welding rectifier, Converter, Welding analog power supply, etc. Apart from analog controls nowadays you can find digitally-driven machines that will ease switching into parameters like current, voltage, arc length, type of current, and pulse current output.

When choosing a welder, you should consider these factors. At first, you should decide what processes you are capable of. That means if you are a beginner, you should probably go for the MIG welder type and if you are a professional welder your best choice would be the high-tech TIG welder type. TIG welding machines are quite used in the aviation and automobile industry where thin metal welding is prevalent. As discussed above DC power welders are the ones you should consider for a long-time business and always used the quality products which are recommended by your industry requirements.

Normally in the aviation Industry welding is considered one of three repair procedures where the metal can be joined without fasteners. The welding machines need to be selected to satisfy the requirements for the type of welding being undertaken. Apart from that, the welder who has been trained in welding processes for each metal needs to use the welding equipment manufacturers’ information to decide the equipment good to go for the welding.

Here are the welding machines types which are often available in the online market that can be recommended based on the above for professional welding applications.

SOLDERING STATIONS

High-tech soldering stations are widely used in professional soldering applications mainly for temperature control rather than using soldering iron only for soldering tasks. The soldering iron cannot control the temperature as it only heats up to a specific temperature. Through temperature control by a soldering station following advantages can be obtained.

To keep solder tip temperature as low as possible to avoid oxidizing before using it for the soldering task.
Controlling temperature prevents damage to the components you are soldering. Some electronic components are very heat sensitive. Holding the tip against the lead for long will transfer heat into the semiconductor and cause it to damage.
Quick tip heating – With a temperature-controlled tip, you can apply a lot of currents, heating the tip to temperature quickly. Once at temperature, the current is reduced to prevent the tip from overheating which will ruin the tip very quickly.
Temperature recovery – When you touch a tip to the metal you want to heat, this removes heat from the tip. The controller will sense this and apply more current to bring the tip back up to the desired temperature.
A temperature-controlled tip allows you to leave the tip hot between uses. With a simple uncontrolled iron, the tip will burn up if you leave it for long.

When considering the above you will probably buy a soldering station for your professional applications unless it causes more disadvantages including higher power consumption due to the inability of temperature control.

A high-tech soldering station provides the above-mentioned advantages with ease and a comfortable manner. Apart from that, you will get a digital screen with safe modes, an additional hot air gun for rework, shrink tube applications, and for cleaning the work area after soldering.

As stated earlier, you are the one to choose the perfect soldering station that will suit your capability. You need to consider the wattage, quality, and safety features after choosing the desired unit. Higher wattage means higher power to work for long times. The build quality is also essential for any periodic checks for the maintenance in the manuals. The soldering stations are usually two types ESD safe & non-ESD safe which represent the measurement of electronic discharge when an object with different potential gets close. It is good to have ESD-safe stations as it avoids the forming of static charge on iron and station when soldering applies.

Properly maintained stations can be last for years without replacement. Check whether the high-tech soldering irons come with accessories sets including soldering tips, sets of tweezers, a de-soldering pump, a cleaning sponge, etc. Normally stations come with the above sets but keep in mind to buy the whole pack otherwise you will need to waste money buying individual items separately.

Following high-tech soldering station can be recommended for industrial soldering applications. It covers all the aspects discussed above including wattage, quality, and design standards.
