The ELMA CM VISION Alu industrial manual welding gun in combination with the ELMA VMC VISION Alu control cabinet provides an efficient and reliable spot welding system for joining aluminium in the industrial sector.
The design of the complete system follows the Keep it small principle and, in addition to an optional external water recooler, consists of only these two components - no additional equipment or mechanical devices such as circulating processing belts or cap cleaning systems are required.
In addition, 16 mm standard electrode caps (copper chrome zirconium) can be used. In addition to the "VISION AV Alu" welding programme for aluminium, the system is also supplied with the familiar welding programmes for high-strength and ultra-high-strength steels.

User information
Positive welding results have so far been achieved with the aluminium material classes 5000, 6000 and 7000.
In view of the large number of aluminium alloys on the market and the complexity of the aluminium spot welding process, ELMA-Tech cannot guarantee at this time that the aluminium welding process presented in this information will allow every aluminium alloy to be welded reliably with the same maximum number of spots.
Only after welding tests have been performed, precise statements can be made whether a certain aluminium alloy or aluminium joints can be reliably spotted.
