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
