Stick Welding Can Benefit from Pulsed Welding Current
4 August 2021
With considerably more productive welding processes such as MIG/MAG taking over the welding industry, the role of stick welding (MMA) has become smaller in recent decades. This is why the majority of welding equipment manufacturers have focused their most significant efforts on MIG/MAG welding rather than stick welding, and introduced new features made possible by new power source technologies.

What to consider when buying a welding machine?
Once a welding machine has reached the end of its life cycle, or a company expands its operations, it's time to find a new best friend for the welder. There is a wide range of welding machines on the market, and in many cases, comparing different brands and models is challenging. What kind of things should be considered when purchasing a welding machine?

Stable arc ignition improves welding quality and reduces costs
In MIG/MAG welding, arc ignition plays a key role in welding quality. Any instability will result in the post-weld cleaning of spatters, which eats up resources and hinders productivity in industrial environments. Available in modern welding equipment, new ignition-enhancing technologies offer additional control of the arc and support the craftsmanship of welders.

Safety that keeps up with welders' challenges and changing risks
Welding safety has become increasingly demanding. The hazards at the arc remain constant, but modern working conditions mean exposure can accumulate over longer shifts and in tighter indoor spaces. As a result, welding PPE needs to be treated as both protection for the welder and proof of compliance. At Kemppi, welding safety PPE is designed and validated in practice through clear requirements, welder-led feedback, and verified compliance with EU PPE Regulation 2016/425, CE marking processes, and relevant EN standards.
