| Model Number | TIG Welding Torch |
This QQ‑150 TIG welding torch has two connector options: cross‑valve connector and local‑style hand‑valve connector. Complete with canvas‑wrapped integrated cable‑hose assembly.
it resists abrasion in workshop and outdoor working scenarios. The lightweight torch handle delivers comfortable grip to lower operator fatigue for long‑time welding.
Excellent internal conductive structure realizes stable arc striking and smooth welding performance.
It fits thin‑plate welding for stainless steel, copper and various alloys, extensively applied in workpiece fabrication, equipment repair and field welding jobs.
Usage Instructions
1.Connection:Align cross‑valve connector or local‑style hand‑valve connector with the corresponding port of TIG welding machine, tighten firmly. Hook up argon gas pipeline to torch gas inlet, make every joint tight to avoid gas leakage.
2.Gas adjustment:Open argon cylinder valve, set gas flow rate based on workpiece thickness; 8‑12L/min is common for thin‑plate welding.
3.Tungsten‑electrode mounting:Fit proper tungsten electrode, adjust its length so that 3‑8mm sticks out from ceramic nozzle.
4.Welding operation:Power on the welder. Adjust built‑in manual valve on torch to control argon supply. Strike arc and keep suitable clearance between tungsten electrode and workpiece to perform welding.
5.Post‑welding handling:After welding, close the torch‑mounted gas valve firstly, wait a few seconds then cut off welder power. Coil the torch hose tidily, prevent sharp parts from scratching or compressing the cable‑hose.
