TIG WELDING OPERATIONS

For TIG welding and TIG pulsed arc welding, you must use a TIG torch ref. 06131 conn For TIG welding and TIG pulsed arc welding, you must use a TIG torch ref. 06131 connected to the euroconector
TIG adapter ref. 56210 (all models) for SR17 and SR26 TIG torches. In this case, the torch has to be connected directly TIG adapter ref. 56210 (all models) for SR17 and SR26 TIG torches. In this case, the torch has to be connected directly TIG adapter ref. 56210 (all models) for SR17 and SR26 TIG torches. In this case, the torch has to be connected directly
