WSME-315S:Suitable for thin to medium aluminum parts and conventional TIG/Pulse TIG operations. Recommended for bicycle manufacturing, aluminum furniture fabrication, general pressure vessels, and pipeline installation.
WSME-400S:Balances thin and medium-thick plate welding with strong versatility. Recommended for pressure vessel manufacturing, general shipbuilding supporting industries, and petrochemical equipment.
WSME-500S:High-current output, suitable for long-duration continuous welding of thick plates and heavy-duty AC/DC TIG/Pulse TIG operations. Recommended for nuclear power installation, large-scale shipbuilding, heavy-duty pressure vessels, and automated welding production lines.
WSME-630S:Maximum power output for extra-thick plates and extreme heavy-duty welding applications. Recommended for large-scale shipbuilding, heavy equipment manufacturing, and large aluminum structure welding. Optional II(a) type synchronization function is available for dual-side arc welding processes.
Q1: What welding modes does this welder support?
A1: It supports AC-TIG, DC constant-current TIG, DC pulse TIG and MMA welding. AC-MMA function can be customized for base models.
Q2: Is parameter adjustment convenient?
A2: Adopt full-digital high-precision constant-current control. Parameters including current ramp-up/ramp-down, pulse frequency, duty cycle, pre-flow gas time and post-flow gas time can be precisely preset for easy panel operation.
Q3: What are the functions of AC frequency and cleaning width?
A3: AC frequency adjusts arc shape; cleaning width removes oxide film on aluminum surface during aluminum welding. Both can be adjusted independently to suit different aluminum alloys.
Q4: What is composite pulse?
A4: Composite pulse allows adjustable composite pulse frequency and width to further optimize weld bead formation, ideal for high-standard aluminum and thin-sheet welding.
Q5: What is the function of VRD anti-electric shock?
A5: It reduces no-load voltage to a safe level of 18V and improves operator safety when working in humid environments.
