Deca: Professional Welders and Battery Chargers

Why choose a Deca Welder?

Deca has democratized professional welding. Whether you're a hobbyist or a blacksmith, you'll find the right machine:

• MASTRO / MOS Series (Inverter MMA): The best-selling. Small, lightweight, and powerful. They weld with rutile, basic, and stainless steel electrodes. Ideal for quick maintenance and working at heights.
• DECASTAR Series (NO GAS Wire): Perfect for beginners. They use flux-cored wire (without a cylinder) for welding outdoors or on thin sheets of metal without piercing them.
• Synergistic Systems: The most advanced machines automatically adjust the parameters. You set the metal thickness, and the Deca decides the wire speed and current.

Why choose Deca Chargers?

Not just charging, but battery care.

• CLASS Series (The Wheeled): The classic workshop "mules." Sturdy, reliable, with a Quick Start function for jumping trucks and tractors with a flat battery.
• FL / SM Series (Electronic): Modern "Pulse" chargers that can remain connected for months (ideal for motorcycles or vintage cars) and recover sulphated batteries.

Frequently Asked Questions (FAQ)

1. Can I use the welder with a generator?
Only if the welder is specifically approved for use with generators (they usually have voltage stabilization systems of +/- 15%). If you connect a standard inverter to an unstable, low-cost generator, you risk burning out the circuit board.

2. What is the difference between Flux Cored Wire and Gas Wire?
Flux-cored wire (Flux) already contains a powder that protects the weld, so a gas cylinder is NOT required (it's cheaper, but produces smoke and slag). Solid wire + Gas (Argon/CO2) requires an external cylinder but produces a very clean, slag-free, and aesthetically perfect weld.

3. Are Deca chargers suitable for lithium batteries?
Warning: Classic models are NOT compatible. You must choose SM series models that specify compatibility with LiFePO4 (Lithium) batteries in the manual. Using a lead-acid charger on lithium can be dangerous.
