Bossweld Powerpulse 250PFC MIG/MMA/TIG Inverter Welder with Dual Pulse Functions and Synergic Programs
The POWERPULSE 250 is a new inverter-based MIG/MMA/TIG Welding machine with Synergic Programs and Dual pulse functions.
The MIG function allows you to weld with gas-shielded wire applications giving excellent, professional welding results. Easy stepless adjustment of voltage and wire feed coupled with integrated digital meters allows easy setting of welding parameters.
The POWERPULSE 250 features MIG welding with Synergic welding programs designed for ease of use with your selected gas mixture. The operator selects the gas mixture and wire diameter they are using and then simply starts welding. Once this is done the operator can make fine adjustments to the voltage for even greater control of the weld pool.
MIG

- Simple to learn
- MIG wire is fed through the gun to create the weld pool
- Gas or flux prevents oxidation in the weld
- Weld with or without gas
- Point and pull the trigger
- Great for maintenance, small projects & automotive repairs
METAL TYPES
Mild steel, stainless steel & aluminium
The stick welding (MMA) capability delivers easy electrode welding with high-quality results, including cast iron, stainless steel and low hydrogen.
STICK

- Easiest process to learn
- Best choice for quick repairs
- Slower than MIG welding
- Forgiving in dirty/rusty environments
- Not recommended for thin sheet metal welding
METAL TYPES
Mild steel, stainless steel & cast iron
The added Lift-Arc DC TIG capability delivers perfect arc ignition every time and a remarkably smooth stable arc produces high-quality TIG welds. TIG functionality includes adjustable down slope & post gas as well as being gas solenoid-valve equipped.
Arc welding with the POWERPULSE 250 machine is suitable for all positions of welding for various plates made of stainless steel, carbon steel, alloyed steel etc. Applications apply to pipe installation, petrochemicals, architecture equipment, car repair, bicycle repair, handicrafts and common steel fabrication.
TIG

- Gives a better weld finish
- Accurate heat control
- Considered the most challenging process to learn
- Good way to weld thin material
- Argon gas is required
METAL TYPES
Mild steel, stainless steel & aluminium
An additional feature is the spool gun-ready function that allows the simple connection of a spool gun for the use of thin or softer wires that don’t have the column strength to feed through MIG torches, such as aluminium wire. In the JOB mode, 100 different JOB records can be stored and called , improving the quality of the welding process .
The POWERPULSE 250 machine has built-in automatic protection functions to protect the machine from over-voltage, over-current and overheating. If any one of the above problems happens, the alarm lamp on the front panel will light up and output current will be shut off automatically for the machine to protect itself and prolong the equipment's life!
FEATURES
