KOBEWEL S Series MMA/TIG Inverter Welding Machine (Made in Japan)

HIGHLIGHTS:

The KOBEWEL S Series MMA/TIG Inverter Welding Machines are engineered in Japan to deliver reliable welding performance across a wide range of professional and industrial applications. The series spans six models from 160A to 400A output, giving users a configuration to match light, medium, and heavy-duty welding requirements — all built on a common foundation of Insulation Grade F and IP23 ingress protection.

S160i is the entry point of the series, delivering a rated output of 160A at a 100% duty cycle from a single-phase 220V/60Hz supply, in a compact 11kg unit suited to light-duty stick welding tasks.

S200i steps up to a rated output of 200A, also at 100% duty cycle, running on a single-phase 220V supply. For installations requiring power flexibility, the S200iD is the dual-voltage variant of the same machine — sharing identical output specifications to the S200i, but wired for 220V/440V dual power supply input.

S250IE is the Digital Type model of the series, delivering a rated output of 250A at a 100% duty cycle, and is rated for electrode sizes from 1.6–6.0mm across material thicknesses of 1–14mm, with TIG capability supported via an optional air-cooled torch (sold separately).

S350i moves into heavy-duty territory with a 350A rated output on a 220V three-phase supply, supporting material thicknesses up to 18mm with electrode welding and up to 10mm with TIG (optional torch required).

S400i tops the range with a 400A rated output and flexible 220V/440V three-phase power input, supporting the same 1.6–6.0mm electrode range and up to 18mm material thickness as the S350i, in a heavy-duty 38.5kg chassis built for the most demanding industrial welding tasks.

FEATURES:

• Made in Japan – Engineered in Japan across the full S Series lineup.
• 6-Model Power Range (160A–400A) – A configuration to match light, medium, and heavy-duty welding requirements.
• 100% Rated Duty Cycle – All six models in the series are rated for 100% duty cycle at rated output.
• Digital Type Model Available (S250IE) – S250IE is the Digital Type unit in the series, distinguishing it from the other models in the lineup.
• Dual Voltage Option (S200iD, S400i) – S200iD and S400i offer 220V/440V dual power supply input for flexible installation; S200i, S160i, S250IE run on standard 220V single-phase, and S350i on 220V three-phase.
• Insulation Grade F – High-grade motor/transformer insulation across all models for reliable continuous-duty performance.
• IP23 Protection Rating – Ingress protection rated for demanding job site and workshop environments.
• TIG-Capable Models (S250IE, S350i, S400i) – Rated for both electrode (MMA) and tungsten (TIG) welding, with an air-cooled TIG torch available as an optional accessory (sold separately).
• Standard Accessory Kits Included – Each model ships with a welding helmet, electrode holder, ground clamp, terminal lug, and copper welding cable (specific ratings vary by model — see accessories table).

*TIG Torch not included on TIG-capable models — sold separately.
