What is Duty Cycle in Welding and How is it Calculated?


Duty cycle refers to the period you can run your welding machine at the recommended amperage. It is usually measured in ten minutes. For example, at 200 amps with a 30% duty cycle, you can run the welding machine for 10 minutes. In the first 3 minutes, run the machine continuously while maintaining 200 amps. […]

How to Weld Plastics

TANKCO Plastic Welding Repair Kit

Plastic welding is the process of joining softened thermoplastics surfaces using heat. When compatible thermoplastics are subjected to heat, they create a molecular bond that subsequently leads to plastic formation. During production, you have to press the surfaces, subject them to heat and pressure, and then cool off. The heating techniques used are responsible for […]

What is Flux-Cored Arc Welding? Understanding it Thoroughly


How Does It Work? Flux-cored welding uses the same equipment as MIG welding. This includes welder/inverter, wire feeder, semi-automatic welding gun, and ground clamp. Since the power source is based on CV (constant voltage) which can be adjusted, this means that the arc length will stay constant throughout welding. The overall current can be changed […]

What’s the Best Gas to Use for MIG Welding?


MIG welding utilizes a hand-held gun with a spool-fed cable electrode and a gas nozzle that releases a gas stream to the welding site. This gas stops nitrogen and oxygen contact and other ambient gases with the weld bead. It makes sure that there are strong and consistent results. Contamination can result in a poor […]
