1. What preparations need to be made before using a cold welding machine?
The core preparations before using a cold welding machine include equipment inspection, environmental preparation, material handling, and protective measures Equipment inspection • Power connection: Confirm that the input voltage (220V/380V) matches the equipment nameplate, and the grounding wire must be reliably connected • Gas system: Check that the pressure of the argon gas cylinder is ≥ 0.5MPa, the gas pipe is not aging or leaking, and the flow meter adjustment range needs to be within 8-15L/min. • Welding gun status: Control the tungsten electrode extension length within 3-5mm, and check that the ceramic nozzle has no cracks. 2 Work environment - Clear flammable materials within a radius of 1.5 meters, equipped with 2 or more 4kg dry powder fire extinguishers - Environmental humidity should be less than 70%, temperature should be greater than 5 ℃ (low temperature can cause protective gas condensation) - Fixed equipment should be installed on a cement base, and mobile equipment should be locked with casters Material processing - The welding area of the base material needs to be polished with an angle grinder to a metallic luster (Ra ≤ 12.5 μ m) - Acetone should be used to remove oil stains before welding stainless steel, and stainless steel should be brushed to remove missing and oxidized layers - Welding wire should be sealed and moisture-proof, and the surface oxide film should be removed with sandpaper before use Safety protection - The operator must wear an automatic dimming welding cap (shading number DIN9-13) - wear flame-retardant work clothes, leather hand lifting cover with a length covering the forearm 2/3- set up a warning

2. What things need to be checked at gas stations
The daily and regular inspection items of vehicle gas stations are divided into three core areas: safety, equipment, and operation, which need to be strictly implemented in accordance with industry standards. Some high-risk inspections need to be operated by certified professionals.
. 1. Safety inspection items - Combustible gas leakage detection: Focus on checking the positions of gas dispensers, gas storage wells, pipeline interfaces, valve flanges, etc., use portable combustible gas detectors to detect, inspect every 2 hours, and check every 4 hours for night duty - Fire protection facility inspection: confirm that the pressure of dry powder fire extinguishers and carbon dioxide fire extinguishers is normal and effective, the fire sand pits and fire hydrants are unobstructed, emergency lighting and evacuation signs are intact and usable - Lightning and static electricity detection: check whether the resistance value of the grounding pile meets the standard of ≤ 10 Ω (data from the 2022 version of the "Design and Construction Standards for Automobile Gas Stations" GB50156-2012), Once a year, a third-party organization needs to be commissioned to inspect the safety warning signs: check whether the signs of no fire, speed limit, gas filling instructions, etc. inside the station are complete and clear,
