Welder Generator Parts
What are the Applications of a Generator Welder?
Every welding machine needs a power supply. Most of the machine depends on the electric power supplies available in most of the shops, garages, industries, and homes. A welder generator is having its own inbuilt power supply.
- The handy equipment where an electrical connection is not available. It is better utilized by farmers to repair tractors, combines, irrigation pipes, spreaders, seeders, fencing, hitches, and trailers repair.
- The welding generator becomes handy on a ranch for erecting fences & holding pens, trailers, wagons, and other equipment used in the ranch.
- The construction people make use of this welder generator for framing and steel support in the buildings.
- The industry where welding is carried out in an area where no external power source is possible, will need welder generators to construct, repair metal structures, and metal components.
- They may be a useful option for emergency power situations along with welding facilities.
- In conditions of natural disaster as tornadoes, hurricanes, ice storms, and floods have occurred, businesses, and homes, are left with no power for a longer period of time.
- A welding generator is armed with a fairly large fuel tank to run continuously for hours together under a continuous watt load.
- Few welder generators can offer you enough output power for the need of a house or small business. They can deliver the start of big appliances like a furnace, water heater, and air conditioner.
Engine Driven Welder and Generator Combo, Purchaser’s Advisory
PRINCIPAL ELEMENTS TO THINK ABOUT WHEN PURCHASING A WELDER GENERATOR COMBO
You have decided to shop for a unit in step with your project. Your purchasing considerations must include:
- Type of the engine and fuel
- Functioning versatility of the unit
- Power type AC or DC or Both
- Noise pollution level of the model
- Generator style for portability and size
Now we are going to be scrutinizing the features of those pieces of kit, your options, advantages, and shortcomings of all different parameters.
All the engine-driven power source utilizes one of these three fuels categories, named diesel, gasoline/petrol, and liquid propane (LPG).
Many of these small portable units consume gasoline. The gasoline engines give in lower fuel utilization. They are easy to start in even extreme frosty weather. The gasoline is more nominal than propane and diesel.
The extended period of welding jobs may need a diesel engine as this fuel offers the long run time than propane and gasoline. In the situation of an easy supply of diesel at the site, the diesel welding generator will be the first choice.
Propane is found to be an expensive fuel but has few benefits like it burns clean, can be kept longer, and can burn in not quite a ventilated area.
Equipment’s Design and Weight
Thumb rule is more the power of the equipment, the heavier and bigger is its size. This is because of more components to make it more powerful. The design of the machine affects significantly the weight, size, and portability.
There are two designs available one is open/ tube frame type, and the second is the enclosed case of the machine. The open type of welders is lighter and compact than the enclosed one. But enclosed type welders furnish powerful protection to the engine better than an open frame type welder.
Suppose you are having welding jobs at many locations then portability becomes of paramount importance. The powerful unit should have transportability to mount it on your truck back for a meaningful welding job.
The tube frame type designs are lighter than enclosed cases and become easy to lift by hand or crane. Some designs have added wheels for portability.
The process and project need to decide the required power output. Bigger the project more is the power required. DC Power output is the consideration of your project.
You may need AC power output for your project needs. Your need may be overhead light, grinder, drill machine, and cutting equipment. Time to calculate total DC power and AC power requirement as per your project before you settle with a welder generator purchase.
Duty Cycle of the Generator Welder
The duty cycle shows how long you can run the equipment at a given amperage in a 10 minutes cycle. Suppose your welder’s duty cycle is 60% at 220 amperes, you must pause your welder for four minutes after six minutes of uninterrupted welding.
Generally, the duty cycle goes up when the amperage of the welder goes down. It means at lower amperage it may carry the welding for a longer period of time.
Cost and Payment Terms
In any purchase, the price tag is always the first consideration. But it should never be the only consideration as you may end up with substandard products and restricted functionality. Look for the welder where payment terms are on equated payments for a period.
The welder power combo is slightly at a higher price than an electrical welder. You can use it away from your shop, may be in the field, ranch, and farm. It is advisable to spend more on better amperage, better fuel efficiency, and a better brand. You end up saving on running the equipment and spares replacement in the long run.
Noise Pollution Level
Welding generator units are louder than traditional welders. If you are welding in a remote area or on a farm, then never compromise on power in keeping the noise level below 100DB. But if you work in an apartment complex, then the noise level is a significant factor.
If your work warrants you to operate in other homes, choose the hunt that produces a noise of less than 90DB, which is louder than a vacuum cleaner but the same level as the city traffic.
DC/AC Power Type
DC and AC are the polarities of the current that the welder generates and run through electrodes. DC is electricity that flows in a direction that has a voltage with a harmonious polarity. Instead, AC is the electricity that switches directions, a periodical reversal of voltage.
DC remains the most popular type used as it produces a smooth and stable arc. These DC machines are very nominally priced and easy to operate.
Accessories and Fitments
Once you are buying new equipment you may require some accessories for the equipment and for the job you are undertaking. The commonest accessories include electrode holder, extension cables, remote control, keys, and spanner.
Confirm with the supplier fitment list and try to buy the same.
Find out the warranty period before shopping for the generator welder. The manufacturer of the welding generator provides a warranty for engine and batteries separately. Generally, the warranty agreement is for 2-3 years.
Most of the companies ask you to drop the machine which needs any service and repair. In Asia, an economical model of Cruxweld offers you warranty, which is great worth for its cost.
Proposed Multi-Process Items
A welder power combo bears significant benefits of location independent. You are free to work anywhere, fields, seashore, roadside, and rooftop even. Now you are in a situation when you are out of fuel and even do not have electrical supply nearby. A filled fuel canister serves here as backup fuel storage.
Welding Hose Pipe
Once working on your project and you are to reach the area far away. The small hoses make the movements of the welder restricted and difficult. Best quality welding hoses of 50-70 feet extra makes the unit more mobile and more productive.
When you have shortlisted and purchased a unit, then you always wanted to make the clean and neat welding. The good pair of electrode holders will help to make the tidy welding. Extra pair of electrode holders may remain handy.
Protective Shield for Unit
Sufficient protection of the welding machine requires during the downtime. A weather cover is essential to prevent the accumulation of dust & corrosion by keeping the moisture at bay.
This cover not only improves the life span of the unit but improves its performance to its maximum. Any deterioration in the equipment will reduce the duty cycle and increase the chances of defects.
Working alone and moving the heavy machine alone waste lots of energy and time. You need high-quality running gear or wheels for bulky and heavy welder generators.
The gear and wheels make transportation, adjustment, positioning effortless. This exercise will prevent any personal injury and damage to the equipment.
The welder generator combo with sufficient power will be able to run other tools like cutter, grinder, drills, and light. Everything you wish to operate, you need good quality extension cables for it.
A sufficient length and excellent quality leads will save your time if only few people are working on a project.
Electrodes Identification – A.W.S. Standards
There are few dazzling welder generators available in the market, and we have reviewed the top six welder generator combo and summarized how much they can do for you.
