KR-200/350/500 Heavy Industry Thyristor CO2 MAG Gas Shielded Welding Machine MIG Welding Machine

Overview of KR-200/350/500 Heavy Industry Thyristor CO2 MAG Gas Shielded Welding Machine MIG Welding Machine

Thyristor is a solid-state semiconductor device composed of four layers of alternating P- and N-type materials. It functions as a bistable switch, conducting current only when triggered by a gate signal, and remains conducting until the voltage across it drops below a certain threshold. Thyristors are widely used for controlling high-power electrical circuits, offering efficient and reliable performance in various industrial and electronic applications.

The KR collection welding machines take care of heavy industrial jobs. They collaborate with CO2, MAG, and MIG processes. These are difficult machines built for requiring workshops. 3 versions exist: KR-200, KR-350, KR-500. The numbers reveal their power output in amps. Select the version matching your typical welding density and job needs.

All models utilize reliable thyristor control innovation. This gives secure welding arcs and regular efficiency. Power input is 3-phase 380V. This fits commercial settings. Outcome welding current adjusts across a vast array. The KR-200 provides 40-200 Amps. The KR-350 offers 60-350 Amps. The KR-500 delivers 100-500 Amps. Outcome voltage likewise adjusts for each and every version. This makes certain proper arc qualities for different products and cords.

Obligation cycle issues for continuous procedure. The KR-200 runs at 200A for 60% of a 10-minute cycle. The KR-350 performs at 350A for 60% task. The KR-500 handles 500A at 60% task. Greater task cycles mean much less downtime air conditioning. The devices utilize forced air cooling. Fans kick in instantly to stop getting too hot. Built-in thermal security includes security.

The devices are literally durable. Size enhances with power. The KR-200 measures around 700mm long, 400mm wide, 700mm high. Weight is about 150kg. The KR-350 is bigger, regarding 800mm long, 450mm vast, 750mm high. Weight nears 200kg. The KR-500 is the biggest, roughly 900mm long, 500mm vast, 800mm high. It considers concerning 250kg. They need sturdy positioning. Connection cords are conventional commercial length. Wire feeders are commonly sold individually.

5 FAQs of KR-200/350/500 Heavy Industry Thyristor CO2 MAG Gas Shielded Welding Machine MIG Welding Machine

Here are 5 FAQs for the KR-200/350/500 Welding Machine:

What power supply does this machine need?
Check the specific model’s rating plate. The KR-200 often uses 220V single-phase. The larger KR-350 and KR-500 models usually need 380V three-phase power. Using the wrong voltage damages the machine. Always verify your workshop power matches the machine.

How thick metal can it weld?
The machine handles different thicknesses. The KR-200 welds steel up to about 8mm. The KR-350 handles up to 12mm. The KR-500 manages the thickest steel, up to around 20mm. Actual thickness depends on wire size and your welding technique.

What gas does it use?
This machine performs MAG/MIG welding with shielding gas. It uses CO2 gas alone. It also uses mixed gases like Argon/CO2. The gas type depends on the material and the weld quality you need. Always use the correct gas for your job.

Is this machine easy to move?
No, it’s heavy. The KR-200/350/500 are industrial machines built tough. They have sturdy frames and large transformers. They are designed for fixed workshop use. Moving them requires equipment like a forklift. They are not portable.

Does it need special maintenance?
Yes, basic care is essential. Keep the machine clean and dry. Dust and moisture cause problems. Regularly check wire feed rollers for wear. Inspect the welding torch cable and liner. Blow out dust from the inside with compressed air periodically. Good maintenance prevents breakdowns.
