Welders

Welders in the power family join metal at industrial duty cycles. Multi-process machines dominate the class, with engine-driven units for line-power-free sites.

Cómo funciona

The power source shapes current to the process — constant current for stick and TIG, constant voltage for wire — with output range setting weldable thickness and duty cycle setting sustainable output. Engine-driven units generate their own current and typically export several kW of 120/240 V auxiliary power besides.

Tipos y variantes

Multi-Process Welder: Welder that runs MIG, TIG, and stick processes from one power source.
Engine-Driven Welder: Welder-generator that welds and supplies auxiliary power without line electricity.

Cómo elegir

Site power decides the family: shop and powered-site work favors multi-process inverters for flexibility and arc quality; pipeline, structural, and remote work runs on engine drives. Output amperage follows material thickness, and duty cycle at working amperage — not peak output — is the spec that governs production.

Preguntas frecuentes

What is a multi-process welder?

One power source running stick, MIG, and TIG by mode selection — one machine covering repair, fabrication, and finish work that once took three.

Why choose an engine-driven welder?

Independence. It welds at full output with no line power and feeds grinders and lights from its auxiliary outlets — the field-erection and pipeline standard.

How does duty cycle limit production welding?

It states welding minutes per ten at an amperage — 60 percent at 250 A means six minutes arc-on, four cooling. Sustained production needs a machine whose rating exceeds the planned arc time.
