Mobile welding Toronto – High-rise welding in construction of High–Rise Building


Welding on a construction site of high-rise apartment buildings face the following challenges:

  • CWB & WSIB requirements
  • Lack of 220v electrical power
  • Inability to effectively extend the welding leads from the ground level to the level above the 3rd floor
  • Necessity of power generation at least 130A during welding process
  • High cost and unreliability of rental units
  • Scarce space for large generator-driven welding unit
  • Difficulties dragging heavy welding cables through the construction debris and scaffold supports


JW Portable Welding & Repairs specializes in mobile & portable welding services needed in construction of high-rise buildings. Further specialization involves modifications of platforms, stair cases and handrails on higher levels. The tools we have at our disposal include:

  • the main unit, diesel driven Lincoln welding machine (includes 800ft of welding cables)
  • torch unit (400ft hoses)
  • self-propelled welding machine that can be lifted by the crane and is small enough to travel between scaffolds
  • portable machine operating at 110V
  • portable machine operating at 220V
  • portable set of torches


JW Portable Welding & Repairs is CWB and WSIB certified. We use our own, well maintained and modified welding machines. Our relatively light, generator driven, portable welding machine is especially useful as it can be lifted by two men to be carried down the stairs or hoisted by engineered hookup to be placed on the highest floor of the high-rise building. The machine is equipped with large size casters that allow mobility through the construction debris and is small enough to squeeze between the scaffolds’ supports. The welding cables are light and our welders move them quickly to the desired location.


Project Expectations:

  • Project must be significant enough to warrant 10 hours of work per day with at least 1 full day of work
  • Client pays for travel from London to the Site as well as accommodation if necessary


During the initial inspection, we determine the details of technological requirements and safety in order to ensure a safe and efficient working environment.
