Pulse MIG Welding

Pulse MIG is ideal for metals and applications where controlling heat is difficult when using standard MIG process, and/or where high weld quality and appearance is desired.

Pulse MIG welding Aluminium
Aluminium is a high thermal conductor (which means that heat is quickly transferred away from the weld pool), with a relatively low melting temperature. Pulse MIG process allows the operator much greater thermal control to apply enough heat for a successful weld, whilst avoiding distortion or burn-through.

High Frequency TIG Welding

With this cutting-edge setup, you'll be confidently ready to tackle any welding challenge. The High Frequency Start TIG mode gives welders a powerful advantage at difficult joints – enabling them to perfect more advanced techniques and create precise seams with non-contact ignition that works from even the most challenging angles.

Plasma Cutting

If you're looking for a top of the line plasma cutter that can handle cuts on almost any type of conductive metal, look no further than SSimder SD-4050 Pro. With the ability to cut up to 3/4" (20mm) thick stainless steel, copper, or aluminum pieces with ease and speed, this powerful machine allows you to perform large jobs in a short period of time.

Gas Metal Arc Welding

Unleash the power of precision welding with the SD-4050 Pro MIG Welder! You'll be able to customize your experience by selecting from either CO₂ or mixed gas.
