QTB-200 MIG Welding Torch

The QTB‑200 MIG welding torch is air‑cooled light‑to‑medium duty gas‑shielded welding torch with OTC‑style connector.Rated 200A for CO₂welding and 180A for mixed‑gas welding at 60%duty cycle,it supports welding wire diameters of 0.8 mm‑1.2 mm,widely matched with OTC‑type MIG welding power sources for general‑purpose semi‑automatic welding work.It integrates current conduction,wire feeding guidance and shielding‑gas delivery,suitable for thin‑and‑medium plate production,repair and on‑site fabrication tasks.

The torch assembly consists of ergonomic insulated handle,copper‑alloy swan neck,complete front‑end consumable set,flexible integrated cable and dedicated OTC rear connector.The heat‑resistant handle shell provides reliable electric‑shock protection against welding spatter,thermal radiation and mechanical knocks.Responsive trigger switch ensures stable arc start‑stop,avoiding mis‑firing or intermittent arc during continuous manual operation.The curved swan neck offers good accessibility for flat welds,corner joints and narrow working positions.

The outer cable adopts wear‑resistant,oil‑proof and anti‑aging rubber jacket.Spring strain relief sleeves are fitted at both handle and swan‑neck joints to reduce cable cracking caused by frequent dragging,bending and twisting on‑site.High‑density stranded copper conductors guarantee low‑resistance current transfer.Full‑range matching consumables include gas nozzles,contact tips,contact tip holders and insulators.All spare parts follow QTB‑200 dimensional standards with good interchangeability.Worn‑out components can be quickly replaced without special tools to minimize workshop downtime.

Compatible with solid wire and flux‑cored wire for carbon steel,low‑alloy steel and thin stainless‑steel sheets.Typical applications cover sheet‑metal processing,light steel‑structure fabrication,hardware manufacturing,machinery maintenance and field installation.3 m,4 m and 5 m cable lengths are available to satisfy different working‑distance requirements.

During daily use,avoid heavy impact to the torch front end.Regularly clear spatter deposits inside gas nozzle,check connector tightness and consumable wear.Replace cracked insulators or heavily eroded contact tips promptly to prevent short‑circuit and torch damage.

Quality QTB‑200 MIG welding torch delivers stable arc performance,smooth wire feeding and effective gas shielding.It reduces spatter and welding reject rate.For small‑to‑medium workshops and engineering contractors,it is a cost‑effective reliable manual welding tool for light‑and‑medium‑load production.
