A Quick Insight Into The Working Of Stick Welding Machines

Being traditional in nature, Stick welding machines have been extremely popular all around the globe. Large industries and MSMEs have been using these equipment due to their low cost and convenience. Let’s have a look at further details.

Also known as arc welding, this machine joins metal to metal by using electricity to create enough heat to melt metal. The melted metal when cooled results in the binding of the metals. This process uses a welding power supply to create an electric arc between metal stick and the base material to melt the metal at the point of contact. You can use these welders directly as well as via alternating current for such purpose.

Working of Stick Welding Machines

The AC Welding machine has a step-down transformer to reduce the input voltage of 220-440V to 80-100V. The DC welding machine consists of an AC motor generator set. It may also contain diesel petrol engine generator set or transformer rectifier welding set. 

AC welding machines work with a power supply of about 50 Hz to 60 Hz and have an astonishing efficiency of 80 to 85 percent. The energy meter denotes an expenditure of deposited metal is 3 to 4 kWh for Alternate Current welding while 6 to 10 kWh for Direct Current welding. The power factor for the AC welding machines ranges from 0.3 to 0.4 while for the DC welding, it stays somewhere around 0.6 to 0.7.

One major disadvantage these hold is the exposure of the user to high-frequency ultraviolet radiations. As a result, the machines require the highest level of protection to the welders while working.

Get the best Stick welders on rent or lease at Red-D-Arc

Also known as Shielded metal arc welding, stick welding is a versatile yet simple welding process. The stick welders can weld various materials like stainless steel, cast iron, carbon steel, ductile iron and even high alloy steels. You can use these portable and cost-effective stick welding machines to weld materials of almost any thickness above 1.5mm. The flux coating itself provides the shielding gas on the welding electrode itself, hence the welder does not require any additional shielding gases with stick welders.

Applications

Stick welding machines find their use in assorted applications across small and large scale businesses, like:

• In steel structure construction
• Steel fabrication
• Underwater welding

Five Tips for Stick Welding

Stick welding is the oldest known welding process and has always been a favourite among welders because of its many advantages.

The Equipment

In this process of joining, an electrical current is used to fuse the metal by melting the tip of the stick or electrode. The core of the electrode melts with the metal and the outer surface and the flux acts as a shield arc which prevents contamination of the weld.

Tips

See below for the top five tips to help your stick welding equipment perform better:

1. Stick welding does not require you to prepare your surface before hand
2. Ensure the correct power settings are programmed
3. Metals should be iron or steel and thicker than 18 gauge
4. Electrodes should be changed regularly for better results and less spatter. 7018 (vertical welding), 6011, 6010 are most commonly used
5. Keep the arc length consistent

To sum up, stick welding can make, mend, and maintain buildings, pipelines, bridges etc. Although considered old, it is still widely prevalent for its affordability, portability and wide range of work. Therefore, if you want precision in your welding efforts, this equipment is a good option.
