Liquefied-gas Cylinder Background Info

Situation

June 2015Factory A is facing the following issues when using its Submerged Arc Welding Machines:

1. Pass rate: 40%-50%

2. Production lead-time: 100s-120s/cylinder

3. Welding current: >400A

4. High power consumption.

Low Pass Rate Low Productivity

High Energy Consumption

Our Solution

July 2015Factory A purchased 10 JOINT PULSED

MIG Welders.

1. Welding current is 300A-330A

2. Lead-time: 65s- 70s per round.

3. Pre-gas time: 10s

Post-gas time: 3s.

Low Heat Input Constant Output Eliminate Burnthrough Spatter-free Welding Short & Concentrated Arc

Performance with Joint Pulse MIG Performance with Other Chinese Brand Pulse MIG
