Welding and Industrial Equipment Hire decisions begin with the task, not the badge on the machine.
01 / Welding and cutting equipment
Hire fleets include MIG welders for steel fabrication and repair, TIG welders for stainless steel, aluminium and precision work, and stick (MMA) welders for structural and site work. Multi-process inverter welders combine several processes in one unit. Engine-driven welder-generators provide welding power and auxiliary power on sites without mains supply, and are common on pipelines, farms, mines and construction sites. Wire feeders, spool guns and water coolers are hired as accessories for specific processes.
Plasma cutters cut steel, stainless and aluminium quickly and cleanly. Oxy-acetylene cutting equipment is widely used, though gas cylinders are usually supplied by gas companies rather than hire companies. Other equipment includes gougers, induction heaters and pre-heat equipment for heavy sections, magnetic drills for holes in steel, and bevelling and pipe-cutting machines. Industrial welding shutdowns may use specialised orbital welding or heat treatment equipment.
02 / Compressors, air tools and general industrial equipment
Portable diesel air compressors power pneumatic tools, sandblasting, drilling and pipeline testing, and are rated by air delivery and pressure. Electric compressors suit workshops. Air tools include jackhammers, needle scalers, rattle guns, grinders and chipping hammers. Air receivers, dryers, aftercoolers and filters improve air quality for painting and sensitive equipment. Size the compressor based on the tools' air consumption and duty cycle.
The wider industrial range includes hot and cold water pressure cleaners, industrial vacuums and dust collectors, abrasive blasting pots, diesel and electric heaters, dehumidifiers and drying fans, and confined space equipment such as gas detectors, ventilation blowers and tripod retrieval systems. During plant shutdowns, contractors often need dozens of items delivered at once and returned on a tight deadline, so many suppliers put together shutdown packages with a single delivery schedule, an on-site container store and a person to manage issue and returns across shifts.
03 / Choosing the right welder
Welder selection depends on the process, material type and thickness, welding position, duty cycle and power supply. Thicker materials require higher amperage, and continuous welding requires a higher duty cycle. Check the power supply available: single-phase units suit smaller jobs, while larger welders need three-phase power or an engine-driven welder. Portability matters for site work, where compact inverters or engine-driven units are more practical.
Consumables such as wire, electrodes, contact tips, nozzles, tungsten and shielding gas are usually supplied separately, and the wrong wire diameter or drive rolls can stop a job on day one. Confirm the gas mix and regulator type for MIG and TIG work, and check lead lengths if the welder will sit at ground level while welding happens up a structure. For structural steel, pressure piping and other code work, both the welding procedure and the welder may need qualification under the project specification, so settle those requirements before choosing equipment.
04 / Safety: fumes, hot work and electrical hazards
Welding fume is a recognised health hazard, and Safe Work Australia and state regulators publish guidance on controlling exposure. Galvanised, painted and stainless materials can produce particularly harmful fumes. Practical controls include portable fume extraction units positioned close to the arc, on-gun extraction for MIG work, general ventilation and suitable respiratory protection, often a powered air-purifying respirator for sustained welding indoors. Welding in tanks, vessels and pits brings confined space requirements such as atmospheric testing and forced ventilation, and a hire supplier can often provide the extraction and gas monitoring equipment together with the welder.
Hot work permits are commonly required on industrial and construction sites, and fire watch, fire extinguishers and removal of combustibles are standard precautions. Electric shock is a risk, particularly in wet or confined conditions, and welders should use equipment in good condition with appropriate earthing and voltage reduction devices where required. Eye and skin protection from arc radiation are essential for welders and nearby workers.
05 / Costs, transport and supplier considerations
Welding and industrial equipment is typically hired by the day, week or month. Beyond the rate, costs can include delivery to site, fuel for engine-driven welders and compressors, consumables, replacement torches or liners, and damage to leads that have been run over or burnt. Some engine-driven units carry a charge per engine hour above a weekly allowance, so check the hour meter reading on delivery and return. Ask exactly which accessories are included, such as earth clamps, electrode holders, regulators and air hoses, and request bundled pricing when hiring several items for a shutdown.
Industrial hire suppliers are best judged on the condition of what arrives. Welders should come with current electrical test tags, undamaged leads and functioning voltage reduction devices where fitted, and compressors should have serviced filters and current pressure vessel inspections where applicable. A supplier who can advise on duty cycle, compressor sizing and fume control is more useful than one who simply quotes. For remote and shutdown work, confirm how quickly a failed unit can be swapped, whether a technician can attend site, and whether spare units can be held on standby during critical periods.
Field checklist
- Confirm the welding process, material type and thickness.
- Check available power supply or choose an engine-driven welder.
- Size compressors by tool air consumption and duty cycle.
- Arrange consumables and shielding gas separately.
- Plan fume extraction and hot work permit requirements.
- Check electrical test tags and voltage reduction devices.
- Clarify engine hour charges and included accessories.
Frequently asked questions
What welder should I hire for site work?
For site work without mains power, an engine-driven welder-generator is often the best choice, providing welding and auxiliary power. For site work with power available, a portable inverter welder may be easier to move. Choose based on the process, material and thickness, and confirm leads and accessories are included.
What size air compressor do I need for a jackhammer?
It depends on the jackhammer's air consumption and working pressure, which are listed in the tool's specifications. Compressors are rated by air delivery, and the compressor should exceed the tool's requirements with some margin. Ask the supplier to match a compressor to the tool.
Do I need a hot work permit for welding on site?
Many construction and industrial sites require a hot work permit for welding, cutting or grinding, to manage fire risks. Permits usually require removal of combustibles, fire extinguishers and a fire watch. Check with the site's principal contractor or facility owner.
Is shielding gas included when hiring a MIG welder?
Usually not. Shielding gas is typically supplied in cylinders by gas companies under their own rental arrangements, while the welder hire company may supply a regulator and flowmeter. Confirm the correct gas mix for your material and process, such as an argon-based mix for MIG steel or pure argon for TIG, and arrange cylinders before the welder arrives on site.
