this welding torch is a special trolley designed for tig welding of medium-thick-wall and large-diameter pipes and tubes. it is suitable for all-position welding of 3~20mm wall thickness pipes. can weld carbon steel, stainless steel, duplex steel and other materials. you can choose to use filling wire or self-fusing cold wire or hot wire. the self-contained integrated wire feeder can realize unwinding wire feeding, and is equipped with a standard 5kg wire reel; it has the function of automatic arc length yaw. it can be used with i-arc400 programmable welding power source, which can precisely realize tig all-position welding, with high reproducibility and ideal welding effect. mainly used in oil pipelines, marine engineering, ships, nuclear power and military industries.
cold wire/hot wire tig dc/pulse all-position automatic welding crawling trolley for large diameter pipe and pipe;
pipes with different diameters are equipped with different positioning guide rings, and the guide rings are driven by rack and pinion;
self-contained integrated wire feeder realizes unwinding wire feeding;
automatic arc length tracking, yaw cover function;
the efficiency of hot wire welding is 3~5 times higher than that of cold wire welding;
the groove form of the workpiece can be v-shaped or u-shaped;
suitable for welding carbon steel, stainless steel, duplex steel and other alloy materials;
