Welding equipment & technology
Power sources, characteristics, inverter technology, shielding gas, and the welding circuit — the hardware every good weld bead builds on.
Power Sources & Characteristic Curves
The power source is the heart of every welding system: it delivers current and voltage. But not every source regulates the same — TIG and stick need a drooping characteristic, MIG/MAG a constant one. Whoever understands the difference understands why their arc behaves the way it does.
Analyse & Artikel →Welding Inverter
The inverter has replaced the heavy transformer: instead of transforming the mains current directly, it first converts it into high-frequency AC. That's why modern welding machines are small, light, and precisely controllable — the standard in every workshop.
Analyse & Artikel →Duty Cycle
The duty cycle tells you how long a welding machine can run at a given current before it needs to cool down. It's shown as a percentage on the nameplate — and if you ignore it, you'll run your machine into thermal protection or destroy it.
Analyse & Artikel →Shielding Gas & Gas Supply
The shielding gas displaces air from the weld pool — without it, every weld bead gets pores and mill scale. To make sure the gas arrives clean and constant, you need a well-thought-out chain: cylinder, regulator, flowmeter, solenoid valve, and nozzle.
Analyse & Artikel →Polarity, Ground & the Electrical Circuit
The welding current flows in a closed loop: machine, torch, arc, workpiece, ground cable. Every weak link in this chain — cable too thin, wrong polarity, poorly placed ground — takes its toll on the arc. These are the most common workshop errors.
