Preheating stage Allows positioning on the joint and preheating of the metal to be welded. PAC SYSTEM arc striking device Pre-gas Up slope Makes it possible to reach the welding current level progressively. Welding Contact Slope down and post-gas Arc on Down slope Avoids the crater (shrinkage cavity) at the end of the bead when welding stops. End setting Allows slower cooling of the weld pool and selection of a “lighted arc” welding cycle, which is very useful when welding in position. HF arc striking device Pre-gas HF striking device Post-gas Protects the weld pool and tungsten electrode...
