Tools and machines for Thermit® welding

In addition to the consumables, we also provide special machines, devices and accessories for performing the various Thermit® welding processes for all types of track, e.g.

  • Flame cutting and preheating, autogenous technology
  • Aligning the rail joint
  • Work equipment for performing the various Thermit® welding processes, e.g. mould shoes, slag pans, clamping devices, preheating burners
  • Machining the rail joint after performing a Thermit® weld 

You can find a comprehensive overview in our product catalogue.

Gas cylinder warmer for propane

Increase reliability at low temperatures for Thermit® welding processes


  • Uniform heat transfer
  • Prevents gas cylinders from icing up at low outside temperatures
  • Guaranteed long service life and reliability even under harsh construction site conditions
  • Oil, dirt and grease retardant, weather resistant
  • Optimum fit and easy to use
  • Retainers for increased stability
  • Overheating not possible


  • Suitable for use together with 19 kg/20 kg and 33 kg propane cylinders
  • Sturdy industrial design made from high grade materials
  • Parallel heating band with positive temperature coefficient and dynamic power output
  • All-round fabric straps with quick release fasteners and additional retaining elements
  • Integrated cutout


Automatic preheating of the Thermit® weld

By automating the preheating and working without compressed oxygen, the propane-air torch Smartweld Jet optimizes your work process. Due to the avoidance of execution errors and the documentation produced on site by means of the Goldschmidt Digital App, the economic efficiency of your welding activities increases. The data is uploaded directly to our database solution Dari® so that data can be analyzed and accessed globally. Smartweld Jet ensures safe and reproducible execution of the preheating process – guaranteeing high weld quality.


  • Reduced transportation and logistics workload through elimination of the oxygen bottles
  • Simplified handling, thus increased occupational safety
  • Relief of the welders due to discontinuation of the setting and monitoring tasks
  • Efficient quality control and documentation of construction and maintenance measures
  • Complete evaluation of Thermit® welding
  • Thermal protection of the casting mould


Petrol compressed air blower for preheating Thermit® welds


  • Preheat Thermit®welds without the need to use technical gases
  • No gas bottles on the track
  • Reduced preheating times compared to similar competitor products thanks to higher heat input
  • Can be applied in all Thermit® welding processes
  • Alternative solution to conventional preheating, e.g. for working underground


  • Offered as a kit with one preheating blower, one complete set of petrol and compressed air hoses, one preheating burner for petrol/ compressed air
  • Dimensions L x W x H = 926 x 404 x 615 mm (excluding handles and wheels)

  • 4-stroke petrol motor: 4.2 KW and 3.6 l tank capacity
  • Handles and wheels optional


Secure, precise ignition of Thermit® portions

The innovative Smartweld Spark ensures reliable and precise initial ignition of the Thermit® portions and is therefore an alternative to igniters which are considered to be hazardous substance.


  • Total elimination of as hazardous goods declared igniters for import and transportation
  • Significant increase of work safety due to omission of hot and open burning igniters
  • Applicable for all crucibles supplied by Elektro-Thermit
  • Service life of one charged battery for at least 20 ignition processes, which means more than one shift before recharging
  • Cost saving consumables


  • Initial spark using electrodes
  • Voltage < 60 V (according DIN 62135)
  • Shock proof and impact resistance frame
  • Integrated LED-lights as well as warning light & alert when ignition starts
  • Weight: 1.8 kg (without case); Dimensions: 340 x 220 x 75 mm incl. battery    
  • Offered as a kit in a convenient case incl. recharger, one battery,  1 pack/10 pieces single use electrodes
